FOR many years, metallurgists have believed that martensite, the hardening constituent in iron-carbon alloys, forms along the octahedral {111} planes of austenite. In 1933, Mehl, Barrett, and ...
SOME observations were made of the effect of heating rate on the martensite (M)→austenite (γ) reversion in a 300-grade 18 per cent nickel maraging steel. These are discussed here with reference ...
