摘要:
利用光学和电子显微镜对20钢在两种切削参数下,形成的积屑瘤的金相显微组织与结构进行了观察.结果表明:积屑瘤具有纤维状结构,积屑瘤中各部位的形变率不同; 某些部位有碳的偏聚现象.其组织类似于珠光体结构; 对积屑瘤的受力状态及其各部位的形变率的差异进行了讨论。大量裂纹的存在.削弱了积屑瘤的强度.是引起积屑瘤不稳定性的因素之一.
Abstract:
By means of optical and electron microscopy,an examination is carried out on the metallurgical microstructure of a built up edge(BUE)which is formed in the 0.2% C steel with two kinds of cutting parameters.The BUE so formed is of a fibrous structure,with
