[钢铁冶金] 贝氏体的表面凹凸定义的各个方面
说明: Criticisms of reports that ferrite laths have a sessile interfacial structure are refuted. A local lattice correspondence,achieved across coherent regions between interfacial defects, suffices to produce surface reliefs and martensitic crystallograp<ha***> 在 2019-03-06 上传 | 大小: | 下载0次
[钢铁冶金] Nb的应变诱导铁素体转变的影响
说明: Effects of the Nb addition on the strain induced ferrite transformation just above Ar3temperature were investigated. Hotcompression tests were performed with varying the true strain up to 1.6 (80% reduction) using Gleeble 1500. After the hotdeformat<jinm*****> 在 2019-03-06 上传 | 大小: | 下载0次
[钢铁冶金] 71型显微硬度计测定铬微裂纹
说明: 为 了满 足 汽车产品中性盐雾试验要求,我厂钢铁件产品采用半光亮镍/光亮镍/高硫镍/微裂纹铬工艺。为了控制产品质量,保证微裂纹铬条数在工艺范围内,检测微裂纹铬条数是一个必不可少的环节。<tianla*******> 在 2019-03-06 上传 | 大小: | 下载0次
