摘　　要：本文通过在GH605中添加微量的Al、Y元素,开展了Al、Y元素对钴基合金显微组织和力学性能特别是高温塑性的影响研究。研究结果表明:GH605合金中添加微量的Y或Y+Al元素可显著提高合金的高温塑性;仅添加Al元素对GH605合金不同温度的强度和塑性影响不大。GH605合金中添加微量的Y+Al元素可细化M_(6)C和M_(23)C_(6)的颗粒尺寸。The effects of Al and Y elements on the microstructure and mechanical properties of cobalt-based alloy,especially the plasticity at high temperature,were studied by adding a small amount of Al and Y elements of GH605 in this paper.The results show that the high temperature plasticity of GH605 alloy Can be significantly improved by adding a small amount of Y and Y+Al elements;The addition of Al has little effect on the strength and plasticity of GH605 alloy at different temperatures.The addition of a small amount of Y+Al in GH605 alloy refines the particle size of M_(6)C and M_(23)C_(6).
