| 摘 要： | 用冷、热弯试验及光学显微镜、扫描电子显微镜和X射线微区分析仪分析研究了含0.3％～0.7％Cu的低合金钢表面氧化层结构及热脆机理。结果表明,Cu的表面富集与表面奥氏体晶界氧化是造成热脆的主要原因。

| Abstract: | The hot brittleness mechanism and structure of surface oxide coating of low-alloy steels containing 0. 3%-0. 7% of copper have been investigated by means of hot/cold bending tests, optical microscopy, SEM and EPMA. Results showed that the surface enrichment of copper and the oxidation taking place at austentite grain boundaries seem to be the main causes for hot brittleness of the material. |

| Keywords: | low-alloy steel copper content hot brittleness surface oxidation rich copper coating selective oxidation electron probe microanalysis |
