摘要

•Sound joint and fine equiaxed α grains reduce FCG rate with good tensile property.•β phase can hinder crack motion and change forward direction.•TA15 alloy with random orientation of α grains exhibits higher FCG resistance.•Local α grains with high Schmid factors are activated to plastically deform.
