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.
Alloying elements in the metal sometimes separate into microscopic particles with distinct shapes. You can aatm and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

This standard is not included in any packages. Microstructural results are typically reported as pictures of the microstructure along with a paragraph interpreting the meaning of the structure.
ASTM E – 07()e1 Standard Practice for Microetching Metals and Alloys
ASTM E specifies what etching chemicals usually acids and procedures are required to reveal the microstructure of different types of astn. APM Testing provides A2LA accredited services for metal microstructure testing at a fair price, zstm prompt delivery, and a detailed test report. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Forgings often show elongation of individual grains which indicate the orientation and flow of the material. 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.
