| 中文摘要: |
| 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. |
| 英文摘要: |
| 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. |
