It may be said immediately that above the upper critical the carbon exists in the iron as a "solid solution," called "austenite" by metallographers.
From The Working of Steel Annealing, Heat Treating and Hardening of Carbon and Alloy Steel by Colvin, Fred H. (Fred Herbert)
Higher percentages of nickel change the martensitic structure to austenite, the steel then being non-magnetic.

Any of these operations not only allows the transformations from austenite to pearlite to proceed, but also relieves internal stresses in the steel.

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 Colvin, Fred H. (Fred Herbert)
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.
