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...

Abstract In this study, the effect of aluminizing temperature and time on the oxidation behavior of Hastelloy C276 are investigated. Aluminide coatings are obtained at 600, 650, and 700 °C for 2, 4, and 6 h, and characterized by microstructural analysis, thermodynamic modelling, and thermogravimetric analysis at 900 °C...

Abstract This study examines crack initiation and propagation in AISI D2 punch tools subjected to cyclic and impact loading using the Finite Element Method (FEM) and the Extended Finite Element Method (XFEM). FEM analysis is employed to identify stress concentration areas and potential failure points, while XFEM facili...
