在试验的焊接条件下，WCX355超细晶钢在热影响粗晶区未有明显脆化，在回火区也未发生软化现象。
Under the experiment's welding condition, WCX355 ultrafine grained steels didn't distinctly embrittle in CGHAZ and didn't soften in tempering zone either.
要包括中间的软化退火和精加后的淬火及回火。
To include the quenching and tempering intermediate softening annealing and finishing after.
硬度能做到61——65hrc成熟工艺是：铸造后软化退火，便于加工，加工后空冷淬火加低温去应力回火。
Hardness can do 61 — 65hrc maturation process is: annealing, softening after casting machining, machining of air cooling after quenching and low temperature stress tempering.
