- Abstract
- A comparative study about the phase stability of equiatomic CoCrFeMnNi alloy of thermodynamic calculation (Thermo-Calc) and experimental result is shown. The alloy was processed by through a highpressure torsion (HPT) process and annealing treatment at temperatures ranging from 900 to 600 C. Phase identification using X-ray diffraction and energy dispersive X-ray spectroscopy indicated that the Cr-rich sigma phase formed during annealing at temperatures lower than 800 degrees C after the HPT process, and fraction of sigma phase increased as decreasing annealing temperature as predicted by Thermo-Calc. The thermodynamic calculation based on the TCFE database was found to be suitable for predicting the possible phases in the CoCrFeMnNi alloy. (C) 2017 Elsevier B.V. All rights reserved.
