Microstructure evolution and room temperature deformation of a directionally solidified Nb-Si-Ti-Cr-Al-Hf-Y alloy

Microstructure evolution and room temperature deformation of a directionally solidified Nb-Si-Ti-Cr-Al-Hf-Y alloy

An Nb-14Si-22Ti-4Cr-2Al-2Hf-0.15Y(at.%) alloy was prepared by directional solidification (DS) with liquid metal cooling, and the withdrawal rates selected were 1.2, 6, and 18 mm·min-1, respectively. The Influence of withdrawal rate and heat treatment on the microstructural evolution, fracture toughn...
