We have no amendments or corrections for this satm. Carbon steel has several structures such as ferrite, pearlite, and martensite depending on how the carbon is distributed in the material.

On a microscopic scale, metal is made up of many grains which can vary in shape and size. Need more than one copy?

Safety precautions and miscellaneous information are also included. Contact us for a quote. Advanced Plastic and Material Testing, Inc. Good microstructural results require significant preparation to obtain a mirror finish with no scratches or edge rounding prior to etching. Differences in microstructure are important because they can help to determine if a metal has been subjected to corrosive chemicals, is softer or harder at the surface, has been deformed, was welded properly, or has been over-heated.

For specific cautionary statements, see 6. Please first log in with a verified email before subscribing to alerts. Add to Alert PDF. High magnification optical microscopy and sometimes scanning electron microscopy SEM is required to reveal important satm.

This standard is also available to be included in Standards Subscriptions. Cast aluminum often has a dendritic fern like structure formed by the distribution of silicon. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standards Subsctiption may be the perfect solution. Microstructural results astmm typically reported as pictures of the microstructure along with a paragraph interpreting the meaning of the structure.

ASTM E specifies what etching chemicals usually acids and procedures are required to reveal the microstructure of different types of metals. An experienced metallurgist is required to interpret the images created. Subscription pricing is determined by: APM Testing provides A2LA accredited services for metal microstructure testing at a fair price, with prompt delivery, and a detailed test report.
