WebPure iron, wrought iron, and extremely low-carbon steels have very little hardening properties and are dif-ficult to harden by heat treatment. Cast iron has limited capabilities for hardening. When you cool cast iron rapidly, it forms white iron, which is hard and brittle. In plain carbon steel, the maximum hardness ob-tained by heat treatment ... WebFor example, Ayenampudi et al. [15] applied the Q&P heat treatment to a medium manganese (4.5%) steel using different temperatures and concluded that, at the …
