Non-heat treatable alloys
From GAWDAwiki
Non-heat treatable alloys are alloys which cannot be strengthened or hardened by application of heat.[1]
The initial strength of alloys in the group depends upon the hardening effect of elements such as manganese, silicon, iron and magnesium, singly or in various combinations. Since these alloys are work-hardenable, further strengthening is possible by various degrees of cold working, denoted by the H series of tempers. Alloys containing appreciable amounts of magnesium when supplied in strain hardened tempers are usually given a final elevated-temperature treatment called stabilizing to insure stability of properties.[2]
