Page 65 As the steel is heated above the critical temperature the size of the austenite crystals tends to grow rapidly.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Fred H. (Fred Herbert) Colvin
However, if the heating has gone above the critical very far, the austenite crystals start to grow; a very short time at an extreme temperature will cause a large grain growth.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Fred H. (Fred Herbert) Colvin
Subsequent cooling gives a coarse texture, or an arrangement of ferrite, cementite and pearlite grains which is greatly coarsened, reflecting the condition of the austenite crystals from which they were born.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Fred H. (Fred Herbert) Colvin
At that moment, in fact, the ferrite, cementite or Page 110 pearlite which previously existed has lost its identity by everything going into the solid solution called austenite.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Fred H. (Fred Herbert) Colvin
Higher percentages of nickel change the martensitic structure to austenite, the steel then being non-magnetic.
