Effect of Initial Microstructure on High Temperature Oxidation of MAR‐M247 Nickel‐Based Superalloy: Experiment and Modelling
The influence of initial microstructure on the high‐temperature oxidation behaviour of MAR‐M247 nickel‐based superalloy was investigated experimentally and supported by CALPHAD modelling. Fine‐grained, coarse‐grained, and columnar microstructures were produced by casting and oxidised in air at 900°C for 1–500 h. Ox...
