Need to know what grade of material you have or if there is a certain element within your part? With X-Ray Fluorescence (XRF for short) analysis we are able scan the sample and provide positive material identification along with detailed element break-downs.

PMI - Positive Material Identification

One of the most common uses of the XRF scanning gun that SMS sees is for PMI (Positive Material Identification). Whether you need to verify that a material and the certification match or identify a piece of material that was separated from its certificate, with the XRF gun, we are able to quickly and easily scan a part/material/sample and identify the alloy.

Portable XRF Capabilities

Do you need us to come to your facility to test your material? SMS’s XRF capabilities are portable. We utilize a state of the art XRF device which we can take with us to your facility to test materials should you not have the ability to send them out. All of the data is captured in the device so we can go back to our lab and analyze the results and put together a formal report. While on site we can give you preliminary results through the digital display of the XRF device.

Material Types

While XRF in general can test for a variety of materials, SMS specializes in the testing and reporting of metals with our XRF device. Should you need tests done for non-metallic samples, we can do that at our facility, but not as a portable service. At SMS we can identify Magnesium through Uranium on the chart of elements with our XRF gun.

ASTM Standards:

  • ASTM E-1476 (Standard Guide for Metals Identification, Grade Verification, and Sorting)
  • ASTM E-572 (Analysis of Stainless and Alloy Steels)
  • ASTM E-1085 (Analysis of Low-Alloy Steels)

Tensile testing is a destructive testing method that measures and provides valuable information on the strength of a particular material, part, sample, weld or other items. The test is performed by increasing the load capacity on the sample until the point of ultimate failure.

A tensile test can be used to ensure a sample meets a minimum tensile requirement and/or to determine what the ultimate strength of the material/sample is.

At SMS we are able to test load capacities from 0 to 60,000 lbs through the use of three different tensile testing machines. Whether you have a small welded component or a large part we have the capabilities to handle your needs.

Bond Strength Testing

Have a coating adhesion that you need to test for strength? SMS can take a slug that has your coating applied to it just as the actual parts would and perform a tensile test where two slugs with the coating are adhered together with a specialized glue.

Compression Testing

A compression is utilized to determine the effects of a given material while being subjected to crushing forces. Samples are fixtured and compressed and depending on the customer requirements and/or specification being tested to, the deformation at given loads is recorded. Overall compression strength among other features can be determined.

Typical Tensile Test Reports Include:

  • Ultimate Tensile Strength
  • Ultimate Yield Strength
  • Elongation

ASTM Standards: ASTM E-8 (Standard Test Methods for Tension Testing of Metallic Materials)

The Scanning Electron Microscope (SEM) is a surface microscopy technique that provides the ability to gain very high resolution of samples. The SEM works by having the electrons directed across the surface of a given sample and when those electrons scatter the image is created. This highly focused beam of electrons is able to provide detailed portions of the sample that would not otherwise be obtainable with visible light thus providing for extremely granular 3 dimensional photos.

With our SEM equipment, Sturbridge Metallurgical can provide

  • SEM Imaging
  • Fractography
  • Energy dispersion spectrometer (EDS) with light element detection for composition analysis:
    • Parent Alloy
    • Residues & Stains

Microhardness testing is the use of mechanical force through a defined testing mechanism that makes an indentation on the material surface which is then measured to calculate the hardness of the given material. The hardness of a material is rated based on its resistance to deformation from the indent made.

The type of hardness testing that is used depends on the material and the surface area available for testing. Sturbridge Metallurgical Services offers the following microhardness testing services:

  • Knoop Hardness Testing
    • Most commonly used for thin or brittle materials that allow for only a very small indentation.
  • Vickers Hardness Testing
    • Can be used on most any material, most common hardness test.
  • Rockwell Hardness and Superficial Rockwell Hardness Testing (B, C, N, T, Y)
    • The most common hardness scale, can be used on a variety of metals such as steel and brass. The material type and the thickness of the material will determine which scale will be used (B, C, N, T, Y, etc).
  • Shore Durometer Testing
    • Used for testing of plastics and rubber materials.

All microhardness testing is done according to the current ASTM standards such as ASTM E18, ASTM E384, ASTM E2240 and/or our customer requirements for the particular test method being used.

ASTM Standards

  • ASTM E-384 (Standard Test Method for Knoop and Vickers Hardness of Materials)
  • ASTM E-578 (Standard Test Method for Linearity of Fluorescence Measuring Systems)
  • ASTM E-18 (Standard Test Methods for Rockwell Hardness of Metallic Materials)

SMS performs grain size analysis and rating per the ASTM E112 standard on either mounted samples or the raw parts themselves (field metallography).

Grain size analysis is used to measure the grain size of a metallic specimens. After a technician prepares the specimen by mounting a cross section and polishing it, they then use the proper enchant to reveal the grain structure.

With proper technique and application, an accurate assessment of grain size in the specimen can be used to verify the effectiveness of a manufacturing process, such as heat treating or tempering. Typically a finer grain size can increase hardness and improve yield strength.

Sturbridge Metallurgical Services has over two decades of experience leading failure analysis investigations in the Aerospace, Automotive, Medical, and Firearms industries. Our root cause analyses provide detailed yet clear conclusions and provide expert recommendations for corrective action. In addition we offer over 6,500 square feet of facility space for failure & litigation conferences.

We take a methodical and detailed approach when it comes to our failure analysis investigation and work to the ASTM specifications and/or customer specifications where applicable.

  1. Review & Discussion
  • The project starts with gathering information from the client (verbally, documentation and parts/components) to allow SMS the opportunity to gain as complete of an understanding as possible of the failure and any potential contributing factors that we may need to take into consideration.
  • Cataloging / Documenting
    • Upon discussing with the client and receiving available information and materials we identify, photograph and catalog all parts/pieces/components that can be sent to us for further testing/analysis. The project receives an overall job number and each component to be analyzed receives a sample identifier.
  • Sample Preparation
    • Samples are taken and prepared as necessary for the highest level of inspection/testing which may include cleaning, cross sectioning, hot or cold mounting, polishing, etching, etc.
  • Analyses
    • After samples are prepared accordingly they are analyzed as needed and the data collected based on the failure and the information the client and SMS are looking to gather. Whether it be on our Keyence, SEM or one of our Stereo Microscopes our mounted samples are made to allow for analysis on each piece of equipment.
  • Reporting
    • After all of the data is collected a detailed report is created noting the reason the customer came to SMS, the methodology taken to gather the results, any data and or images that support the results and our conclusions and/or recommendations.

When professionalism, thoroughness and quality matter to your case, Sturbridge Metallurgical Services is the place to contact for your Failure Analysis Investigation.

Do you need to know the life expectancy of your products wear surface or material? The Taber Abrasion & Scratch testing is an accelerated wear test that provides our clients with valuable information on their organic materials resistance to specific conditions and use over time.

Abrasion Testing

SMS follows the ASTM D4060 specification unless otherwise requested by our clients. Per the ASTM standard the typical load used during this test is 1000g per wheel, unless otherwise instructed by our clients to alter the load.

Flat pieces of sample material are provided to us and we run a set number of cycles. The samples are weighed prior to the test and after the test and the abrasion is determined by the amount of loss after the required number of cycles. Alternatively we can measure the thickness of the material and record the number of rotations until a specified thickness is achieved.

Scratch Testing

With the TABER® Scratch Tester we are able to evaluate resistance to shearing, scratching, gouging, marring, scraping and engraving on a variety of flat, rigid specimens. We are also able to test the relative homogeneity of materials, the adhesive qualities of protective coatings and the effects of age on similar materials.
