摘要
研究了不同温度下 Fe3Al基合金冲击韧性的变化规律 ,确定了冲击载荷下该合金的韧 -脆转化温度 ,考察了冲击载荷下该合金的断裂方式。
The impact toughness of Fe 3Al based alloy at different temperatures was investigated. The tough to brittle transition temperature of the alloy under impact load was determined. The fracture mode, crystal grain structure, and movement of dislocations were examined to explain the change of impact toughness.
