摘要
研究了DO3型Fe—28Al有序合金在25～60℃温度范围内加热时温度对合金拉伸特性和断裂行为的影响。加热有利于合金强度和塑性的改善；合金的断裂行为也随温度的提高由穿晶解理型向韧窝型转变；不同温度下力学性能的变化趋势取决于合金的有序程度。
The influence of the temperature on the mechanical properties and fracture of DO3-order Fe- 28Alalloy at 25-600℃ are researched. The results show that high temperature favours alloy's strength and ductility, andmakes fracture transfer from brittle mode to ductile mode. The transform of mechanical properties at different temperature depends on degrees of order in the alloy.
