摘　　要：研究了稀土对低铬合金模具钢性能的影响,实验结果表明,稀土含量在0.1%左右时,效果显著,稀土对碳化物尺寸、组织的细化与合金元素的相互作用以及对有害元素的影响等的综合作用效果好。In this paper the influence of rare earth on the properties of low-chromium alloy die steel has been studied.The result shows that the properties of alloy steel were significantly affected when it contains 0.1% rare earth,meanwhile the carbide size,refinement of organization,the interaction between alloy elementsand impact of harmful elements were comprehensively affected by adding rare earth.

关 键 词：合金钢 模具钢 稀土 性能
