在低成本粉末锻件第二批试样晶界与晶内均发现了MC型碳化物的存在,此处主要对晶界MC型碳化物的形貌、成分、元素分布、结构等进行表征与分析
The presence of MC carbides in grain boundary and in grain of the second batch of samples of low-cost powder forgings was found. The morphology, composition, element distribution and structure of MC carbides at grain boundary were characterized and analyzed
