摘要
研究了Al-6Mg合金的拉伸行为。结果表明,合金在高温和高应变速率下发生脆性断裂,端口呈沿晶和解理混合状。微量元素促进脆化的发生。
Tensile fracture behavior of an Al-Mg alloy were studied in this paper. The results showed that alloy exhibited ductile fracture when deformned at low strain rate. The alloy showed brittle fracture with intergranular rupture and cleavage facets when deformed at high temprature and high stain rate. The tramp element Na is the embrittling agent.
