摘要：
The crystal structure of alloyed austenite distorted after Ni and Co replaced Fe. The crystal type of austenite changed from cubic structure to tetragon or orthorhombic structure due to the influence of Co and Ni. The ratio (BIG) for gamma-Fe (C) is equal to 2.841, which is higher than that for other alloyed austenite with Co and Ni. The workability of alloyed austenite with Co and Ni are poorer than gamma-Fe (C). The formation of alloyed austenite needs more energy than gamma-Fe (C) at ambient conditions.
