Novel Cast Ni-Based Superalloys with Superb Weldability and Mechanical Properties Screened by a Multiperformance-Oriented Criterion

Abstract

Ni-Based Superalloys

By analyzing numerous alloy compositions through high-throughput thermodynamic calculations and screening them with the multi-performance-oriented criterion, which includes quantitative weldability assessment indices, volume fraction of γ′, electron vacancy number, density, solidus temperature, and freezing range, in article number 2400687, Yi-dong Wu, Xi-dong Hui, and co-workers successfully identify a superalloy with excellent solidification crack resistance and temperature-bearing capacity up to 800°C.
