@@peterdavies6179 Got u . Thanks u for video about Fe-C phase formation . I am falt into ur knowledge. But I am now confused that why people put Cr Mn Mo element to the Fe-C for quenching?

[@peterdavies6179]

@@王雷-m1l I believe Mo suppresses the diffusion of C and inhibits formation of the competing pearlite phase

@@peterdavies6179 Yeah , I completely got this , Your video said FCC wants to back to BCC when temperature is lower , there has 'Memory just like NiTi memory' . But I can not understand why people put the Cr Mn Ni ....etc into the Fe-C for quenching .

I mean, the Mo element is good for FCC to Fe-C formation, but how about the Cr or Ni element?
