4) superficial decarbonization
表层脱碳
1.
The results indicate that superstandard inclusion of material,which leads to primary microcrack at moveing round confectioning,is the principal reason of the crack under 100KN force,superficial decarbonization at heat-treating decreases the admission compression force of crack.
结果表明:原材料内部夹杂物超标是导致产品在绕弯成形时产生初生裂纹,并在热处理后于规定100kN压力试验时产生开裂的主要原因,热处理过程中产生的表层脱碳降低了产品产生开裂的允许压力。
5) decarbonized layer
脱碳层
1.
A study of the decarbonized layer of T8A steel;
关于T8A钢脱碳层研究
2.
Through metallographic examination and microanalysis, it can be observed that at the weld interface of the joints there is a decarbonized layer on the S25C steel side and a carburized layer on the SUS405 steel side.
金相及显微分析可见,在焊接接头的结合界面上,S25C钢一侧存在脱碳层,SUS405钢一侧存在增碳层,这是造成接头组织分布及硬度分布不均匀的主要原因。
6) Total decarburized layer
总脱碳层
补充资料:脱碳层
脱碳层
decarbonized zone
tuotanceng脱碳层(deearbonized zone)含碳耐火材料在高温使用中,表层受氧化性介质侵蚀,碳被氧化后形成的层带。脱碳层的气孔率比原砖显著增大,故强度降低。 含碳耐火材料经熔渣侵蚀后,工作面常附有一层渣层,其成分主要由熔渣与被熔渣溶蚀或冲蚀下来的耐火材料构成。紧接着附渣层的是熔渣与脱碳后的耐火材料相互作用而形成的反应层(见变质层)在反应层内,相互作用生成的液相形成了连续基质,耐火材料的晶粒或颗粒一般多呈蚀损状态并被这些基质所包围。反应层与原砖之间则为脱碳层。脱碳层一般都较薄,反应层则较厚些。 (陈肇友)
