K_9合金是参考国外B—1900合金化学成分,我国自行研制的一种铸造高温合金。合金具有高的高温强度和良好的长期组织稳定性,可用作航空发动机涡轮工作叶片材料。栽所对钽在K_9合金中作用进行了较全面和
K_9 alloy is a reference to foreign B-1900 alloy chemical composition, developed by our own a casting superalloy. Alloy with high temperature strength and good long-term organizational stability, can be used as aeroengine turbine working blade material. Planting on the role of tantalum K_9 alloy carried out a more comprehensive and
