| 摘 要： | 针对高应力磨粒磨损工况条件研制的中铬Ｃ－Ｃｒ－Ｍｏ系奥氏体体堆焊材料ＦＡＷ焊条，具有焊接工艺性好，堆焊金属抗裂性好和加工硬化率高的特点，是替代奥氏体锰钢的理想焊接材料。通过对该材料的化和磨损性能及其机理的试验研究，探讨了合金的冷作硬化及冲击磨损的一般规律。硬化机制以形变强化与碳化物析出强化为主，磨损形式以塑性凿削式去除为主。

| Abstract: | A middle chromium austenitic alloy FAW electrode used for hardface welding of impact wear-resistant has been studied in this paper. It has been shown that the technological property of FAW electrode and crack-resistance are fine and the work hardening rate of its hardface weld is higher than that of manganese steel materials.Base on the work hardening test,impact wearing test and analysis results of their mechanisms,it is shown that the deformation twinning hardening and the dynamic carbide ageing are main forms of the strengthening of FAW alloy,and the chisel cuting is main form of wearing off of the hardaface metal. |
