In order to produce quick and intense carburization the iron should preferably be above its upper critical temperature or 1,600°F.,—therefore the carbon absorbed immediately goes into austenite, or solid solution.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Colvin, Fred H. (Fred Herbert)
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 Colvin, Fred H. (Fred Herbert)
The growth is continually destroyed by the hammering, which should consequently be continued down to the upper critical temperature when the austenite crystals break up into ferrite and cementite.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Colvin, Fred H. (Fred Herbert)
Therefore this steel has to be heated and very rapidly cooled to obtain the ductile austenite structure.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Colvin, Fred H. (Fred Herbert)
He is then able to pick out its component minerals, ferrite, austenite, martensite, pearlite, graphite, cementite, and to show how their abundance, shape and arrangement contribute to the strength or weakness of the specimen.
