摘要
研究了奥氏体化温度对含稀土半钢力学性能的影响 ,结果表明 ,半钢的冲击韧度 (αK)、抗弯强度 (σbb)和相对韧性 (σbb× f )随奥氏体化温度的变化较明显 ,而硬度 (HRC)受奥氏体化温度影响较小 ,当奥氏体化温度为 960℃时 。
Effects of austenitizing temperature on mechanical properties of semi steel with RE were studied.The results show that the α K, σ bb and σ bb ×f of semi steel with RE have been influenced remarvkably by its austenitizing temperature,and the effect of HRC is small.When austenitizing temperature is at 960℃,the comprehensive mechanical properties of semi steel with RE are optimum.
