【摘要】 开发了Cr10VN高碳高铬冷作模具钢，并与Cr12和Cr12MoV对比分析了共晶碳化物均匀性、热处理工艺、硬度、冲击韧性。结果表明：Cr10VN共晶碳化物均匀性好于Cr12略逊于Cr12MoV；高硬性与Cr12相当略高于Cr12MoV,940℃～980℃淬火硬度为64～65.5HRC,200℃回火硬度为62.5HRC,450℃回火硬度仍保持在58HRC；高韧性与Cr12MoV相当高于Cr12,980℃淬火+200℃回火后，纵向冲击功为25.1～32.4J。更多还原

【Abstract】 The high carbon and chromium cold work die steel of Cr10VN has been developed.The uniformity of eutectic carbide, heat treatment process, hardness and impact toughness were analyzed and compared with Cr12 and Cr12MoV.The results showed that the uniformity of eutectic carbide of Cr10VN is better than Cr12 and worse than Cr12MoV, and the hardness is as high as Cr12 and slightly higher than Cr12MoV. The hardness after quenched at 940℃～980℃is 64～65.5HRC, and the hardness after tempered at 200℃ is 62.5HRC, and the hardness after tempered at 450℃ still maintains at 58HRC. The high toughness is equal to Cr12MoV and better than Cr12, and the longitudinal impact energy is 25.1～32.4J after quenched at 980℃ and tempered at 200℃.更多还原
