| 摘 要： | Cr12MoV钢制造的M12螺帽冷镦模经超低温改性处理后，其显微组织发生了转变：钢组织中的残留奥氏体向马氏体转变，析出大量高弥散的碳化物微粒，强化了模具性能，尤其是耐磨性能显著增加，从而提高了冷镦模具的使用寿命。

| Abstract: | It is researched in this paper that the M12 nut cold heading die made of Cr12MoV steel by cryogenic modified treatment, it's microscopic structure generated change: the retained austenite in steel structure changed to the martensite, separated large high-dispersive carbide micro-granules, strengthened the performance of die, especially the wear-resisting property was obviously improved, so increased the life of cold heading die. |

| Keywords: | cold heading die retained austenite tempering martensite carbide wear-resistance |
