ASTM A923 PDF

A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. These test methods will not necessarily detect losses of toughness or corrosion resistance attributable to other causes. The speed of these precipitation reactions is a function of composition and thermal or thermomechanical history of each individual piece. The presence of these phases is detrimental to toughness and corrosion resistance.

More A Scope 1. These test methods will not necessarily detect losses of toughness or corrosion resistance attributable to other causes. The speed of these precipitation reactions is a function of composition and thermomechanical history of each individual piece.

The presence of these phases is detrimental to toughness and corrosion resistance. Rapid cooling of the mill product provides the maximum resistance to formation of detrimental phases by subsequent thermal exposures. Because the occurrence of intermetallic phases is a function of temperature and cooling rate, it is essential that the tests be applied to the region of the material experiencing the conditions most likely to promote the formation of an intermetallic phase.

In the case of common heat treatment, this region will be that which cooled most slowly. Except for rapidly cooled material, it may be necessary to sample from a location determined to be the most slowly cooled for the material piece to be characterized.

The values given in parentheses are for information only. 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. DOI:
