国内外超大直径特种环件材料对比分析
|
Abstract:
为了打破国外对超大直径特种环件材料技术的垄断地位，利用光学显微镜、扫描电镜、ASPEX全自动夹杂物分析仪、拉伸试验机、冲击试验机等对国内外超大直径特种环件材料的化学成分、夹杂物、组织与力学性能等进行了观察检测及对比分析。结果表明：国内添加V、B、RE综合微合金化后的新型钢种42CrMo4M，杂质元素和有害元素较国外环件材料42CrMo4显著降低，且在夹杂物的最大直径、数密度及面积百分比对比发现，自主研发材料中的夹杂物更加均匀，占比更少，纯净度较国外环件材料大幅提升；国内外环件材料组织均为回火马氏体组织，通过对比两种材料的硬度及拉伸冲击性能得出自主研发环件性能优于国外环件，为新型环件材料的进一步优化提供了数据支撑。
In order to break the monopoly position of extra-large diameter special ring material technology abroad, the chemical composition, inclusions, microstructure and mechanical properties of ex-tra-large diameter special ring materials at home and abroad were observed, measured and com-pared by means of optical microscope, scanning electron microscope, ASPEX automatic inclusion analyzer, tensile testing machine and impact testing machine. The results show that: The impurity elements and harmful elements of 42CrMo4M steel after the addition of V, B and RE comprehensive microalloying in China are significantly lower than that of 42CrMo4 foreign ring material. Moreover, compared with the Angle of the maximum diameter, number density and area percentage of inclu-sions, it is found that the inclusions in the self-developed materials are more uniform and take up less proportion. Therefore, compared with foreign ring materials, the purity is greatly improved; the microstructure of ring materials at home and abroad is tempered martensite. By comparing the hardness and tensile impact properties of the two materials, it is concluded that the performance of the self-developed ring is better than that of the foreign ring. It provides data support for further optimization of new ring materials.
