Yield strength alloys

The properties of an alloy (yield strength, toughness, oxidation resistance, etc.) depend critically on its constitution and on two further features of its structure the scale (nm or ym or mm) and shape (round, or rod-like, or plate-like) of the phases, not described by the constitution. The constitution, and the scale and shape of the phases, depend on the thermal treatment that the material has had.

Alloys with 10 to 14% Mn. At approximately 10% Mn, the hexagonal e-martensite is found along with a-martensite in the as-cooled structures Alloys having 10 to 14% Mn are predominantly mixtures of a- and e-martensite after cooling to room temperature, with some admixture of untransformed y (austenite) in the 12 to 14% Mn alloys. The e-martensite phase is metastable and transforms readily to a on deformation at room temperature or below. Alloy yield strength drops dramatically as the volume fraction of e increases for Mn content of >12% (Fig. lb). On the other hand, the tensile strength remains high, presumably...
