Mechanical Properties and Residual Stress Analysis of ODS Ni Superalloy Fabricated by Laser Powder Bed Fusion Process

Oxide Dispersion Strengthened (ODS) superalloys are high-temperature alloys with enhanced mechanical properties at elevated temperatures. This is achieved by precipitating thermally stable fine oxides (such as Y2O3, ThO2) or carbides within the metal matrix1). These alloys are primarily used in the field of superalloys and recently, the principle has been applied to various metals, including aluminum and copper alloys.
