Microstructure evolution and room temperature deformation of a dircctionally solidified Nb-Si-Ti- Cr-A1-Hf-Y alloy

An Nb-14Si-22Ti-4Cr-2AI-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-min1, respectively. The Influence of withdrawal rate and heat treatment on the microstructural evolution, fracture toughne...
