EUROLAB laboratory provides testing and compliance services within the scope of ISO 643 standard. ISO 643 specifies a micrographic method for determining the apparent ferritic or austenitic grain size in steels.
Explain the methods of estimating the average grain size of samples with unimodal size distribution and revealing grain boundaries. Although the shape of the grains is three-dimensional, the metallographic section plane can cut a grain at any point from a grain corner to the grain's maximum diameter, thus producing a range of distinct grain sizes even in the two-dimensional plane.
Metallic alloys are used in many sectors. Especially for cars, trucks, trains, airplanes and other modes of transportation, alloys play a critical role. The characterization of these alloys is especially important for grain size analysis, automotive and transportation industries.
Thousands of standard alloys are in use today, and new alloys with better performance are being developed to meet new demands. For example, many steel alloys are used in the manufacture of cars, trucks, airplanes and trains.
When using these alloys, it is necessary to know the composition and microstructure properties. Tensile strength, elongation, and thermal and electrical conductivity have a significant effect on microstructure properties such as phases, grains, or inclusions. A good understanding of the relationship between microstructure and macroscopic properties is important for the design and manufacture of alloys.
Grains are microscopic crystals formed in alloys during the cooling phase of production. It has long been known that as the grain size increases, the tensile strength and yield strength of the alloy decrease, the elongation at fracture increases and the ductile brittle transition temperature increases. Different test methods are used to investigate the microstructure of alloys.
