摘要
通过不同的退火工艺对高铬铸铁进行处理,用金相显微镜和TEM观察不同热处理条件下的金相组织,并与高铬铸铁的铸态组织进行对比分析,以了解高铬铸铁的微观结构。实验结果表明,高铬铸铁经退火后沿晶界分布的共晶碳化物减少,基体中的碳化物增多,呈颗粒状均匀分布。
Through different annealing processing of high chromium cast iron,this paper uses metallographic microscope and TEM to observe the different heat condition of metallographic structure,and carries out the comparative analysis with as-cast structure of high chromium cast iron,in order to understand the microstructure.Experimental results show that after high chromium cast iron is annealed,eutectic carbide grain along the grain boundaries reduces;the carbide substrate multiplies and is distributed granularly and evenly.
