Cr12钢中共晶碳化物和微裂的商榷
DISCUSSION OF THE EUTECTIC CARBIDE AND MICROCRACKS IN Cr12 STEEL
【摘要】 本文使用彩色金相法,研究了Cr12钢中的共晶碳化物,发现共晶碳化物不是单相的(CrFe)7C3而是由(CrFe)7C3、(FeCr)3C及少量的r相(残余奥氏体)组成。同时发现共晶碳化物上存在着微裂纹。
【Abstract】 The author of this paper used colour metallographic method to study the eutectic carbide and microcracks in Cr12 steel.The results are quite unexpected: the eutectic carbide (CrFe)7C3 is not a single phase but a mixed one. It consists of (CrFe)7C3, (FeCr)3C and a little r-phase. Microcracks are also found in eutectic carbide (CrFe)7C3.
