运用JSM-5610LV扫描电镜对德国产X165CrMoV12钢、国产Cr12MoV钢、9Cr2Mo钢、GCr15钢在不同热处理工艺条件下的金相组织、冲击韧性及耐磨性进行了分析.试验结果表明, 德国产X165CrMoV12钢和国产Cr12MoV钢的组织均为回火马氏体+共晶碳化物,国产9Cr2Mo钢和GCr15钢的组织均为回火马氏体+碳化物+残余奥氏体.国产Cr12MoV钢和德国进口X165CrMoV12钢耐磨性基本相当,9Cr2Mo钢的耐磨性比GCr15钢高了72%.
運用JSM-5610LV掃描電鏡對德國產X165CrMoV12鋼、國產Cr12MoV鋼、9Cr2Mo鋼、GCr15鋼在不同熱處理工藝條件下的金相組織、遲擊韌性及耐磨性進行瞭分析.試驗結果錶明, 德國產X165CrMoV12鋼和國產Cr12MoV鋼的組織均為迴火馬氏體+共晶碳化物,國產9Cr2Mo鋼和GCr15鋼的組織均為迴火馬氏體+碳化物+殘餘奧氏體.國產Cr12MoV鋼和德國進口X165CrMoV12鋼耐磨性基本相噹,9Cr2Mo鋼的耐磨性比GCr15鋼高瞭72%.

Under different heat treatment conditions,the metallographic structure,impact toughness and anti-abrasion analysis were observed by JSM-5610V SEM to X165CrMoV12 imported from German,Cr12MoV,9Cr2Mo,GCr15 produced in China.The results indicated that the structure of German X165CrMoV12 and China Cr12MoV both are tempered martensite+eutectic carbides.The structure of 9Cr2Mo and GCr15 steel are both tempered martensite+carbide+residual austenite.The anti-abrasion of Cr12MoV steel produced in China and X165CrMoV12 steel imported from German are basically same.The anti-abrasion of 9Cr2Mo steel is higher 72% than that of GCr15 steel.
