摘要
对真空退火态93WNiFe合金进行了高温动态拉伸实验。结果表明：随着温度的升高,93WNiFe合金的塑性先上升后下降,在400℃出现峰值；断口形貌由钨颗粒解理型断裂逐渐向钨颗粒与粘结相脱开型断裂转变,塑性受钨颗粒和粘结相变形的共同影响。
The effect of temperature on dynamic mechanic behaviour of tungsten alloy was studied in high temperature tension test. The results show that the elongation increases below 400℃ but decreases above it.The fracture mode changes from tungsten pellet cleavage to detaching of tungsten pellet from matrix. Both tungsten pellet cleavage and it from matrix affect the elongation.
