With over 45 years of metallurgical testing laboratory experience, EAG ensures the highest standard of quality for metallurgical evaluation.
Whether it is a multidisciplinary failure analysis, litigation support, quality control check, or method development, our experienced engineers and metallurgists can be trusted to provide valuable solutions with focused insight and reliable results.
Our laboratories are equipped to handle a variety of tasks with full documentation and traceability. We utilize a wide range of sectioning equipment to isolate areas of interest from a variety of sample types. We can handle anything from raw materials and test coupons to full scale components up to over a ton in weight, made from most metals and alloys. Our experts can selectively target regions as small as 1 micron to analyze a manufacturing defect, corrosive product, fracture surface, coatings and more.
The target material can be tested to your specifications in order to reveal microstructure, determine grain size number, or perform hardness and micro hardness tests. In addition to metallurgical testing techniques, we also have years of experience working with polymers, glasses, ceramics, composites, and electronics. Our services are fully integrated with the EAG Laboratories network to provide options for multi-lab, multi-expert analysis to dynamically fit your needs. Our reliable measurements are applicable for a variety of quality control purposes, including performing tests on potential suppliers or researching a new process. With our metallurgical analysis consulting, we will help you to become more efficient or introduce a better product to the market.
At EAG, we know how critical our analysis is to your success. With our metallurgical testing technical expertise at your disposal, you will have confidence in your business and engineering decisions.
Grain size analysis is used as a quality control tool to ensure that alloys are manufactured to specification. Some examples of this include verification of the heat treatment and condition of the alloy. It can also be used to assist in understanding material failures when errant processing may have occurred.
Microstructural images are used to obtain the grain size. The intersection of the red concentric circles and grain boundaries are marked to determine the grain size number via Intercept Method, which is performed in accordance with ASTM E-112.
The Rockwell Hardness test measures bulk material hardness based on the net increase in depth of impression under an applied load. Rockwell hardness is useful because it is a quick method to obtain mechanical property data from a relatively small sample. Using ASTM specifications, it has a variety of applications including verification of heat treatment and material condition, making it easy to compare samples.
Microhardness determines the hardness of a material by loading a Vickers or Knoop indenter on the surface of a material and microscopically measuring the indentation. This technique can be used to determine the hardness of different constituents within a sample or measuring a gradient found in case hardening or heat affected zone. While conforming to ASTM specifications, we can measure a coating or specific area as thin as 10 microns without compromising accuracy.
Image analysis allows quantifiable data to be captured from a digital x-ray or cross sectional image. The information we can extract includes porosity, constituent percentages, adhesion percentages, and void shape statistics.
