摘要
利用G leeb le-1500D热模拟试验机研究了变形量,变形道次数等对BN bRE钢组织形态的影响。利用光学显微镜和扫描电子显微镜,观察了BN bRE钢试样的组织形态,利用洛氏硬度计测试了试样的硬度值。结果表明:随着变形量的增加,BN bRE钢显微组织明显变细。变形量越大,珠光体的片间距就越小,珠光体的强度和硬度就越高。在其他条件相同时,变形道次数对BN bRE钢显微组织影响不大。
Effect of deformation amount and deformation steps on microstructure of BNbRE steel was studied by Gleeble-1500D. The microstructure of the samples of BNbRE steel was observed by means of an optical microscope and an scanning electronic microscope, and the hardness value of the sample was measured by HRC sclerometer. The results show that with the increase of deformation amount microstructure of BNbRE steel became trivial apparently. Deformation amount was much, the piece interval of pearlite was thinner, consequently, the strength and the hardness were higher. When other conditions are identical, microstructure was not be effected clearly by deformation steps.
