摘要：
The phase and structural compositions of two 25Cr-30Ni-3Mo austenitic alloys with different concentrations of austenite- and ferrite-stabilizing elements have been analyzed after heat and deformation treatments. It has been found that it is the σ phase that is the dominant intermetallic phase in both alloys. The crystallographic parameters of this phase, orientation relationships with the matrix, and the chemical composition have been determined.
