【摘要】 镍基合金是一种最复杂的合金,它被广泛地用于制造各种高温部件,它的相对使用温度在所有普通合金系中是最高的。从高温合金的发展史看,高温合金经历了变形高温合金、普通铸造高温合金、定向凝固高温合金、单晶高温合金四个阶段。同时,给出了合金设计的发展和研究方法,阐述了杂质在晶界偏聚对材料物理性能的影响。更多还原

【Abstract】 Ni-base superalloy is a kind of the most complex alloy,it was used widely as higher temperature components.Its relative applied temperature is the highest in common alloy series.From the developing history of superalloy,it experienced four steps:wrought superalloy、C.C.superalloy、D.S. superalloy、S.C.superalloy.The development and research method of the alloy design was presented.In this paper,and the effect of material physical properties due to elements deflection was discussed too.更多还原
