First-Principles Study on the Structural, Electronic and Elastic Properties of Alloyed Austenite with Co and Ni

Abstract:

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 (B/G) for γ-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 γ-Fe (C). The formation of alloyed austenite needs more energy than γ-Fe (C) at ambient conditions.
