HY N90的特性和应用领域
该合金是时效强化钴镍基变形高温合金,该合金在815~870℃有较高的抗拉强度和抗蠕变能力、良好的抗氧化性和耐腐蚀、在冷热反复交替作用下有较高的疲劳强度以及良好的成形性和焊接性。用于涡轮发动机涡轮盘、叶片、高温紧固件、卡箍、密封圈及弹性元件等。
HY N90的金相组织结构
该合金主要强化相是γ’-Ni3(Ti、Al),在晶内以大小不同的方形颗料关析出,在晶界上也可以见到这种形状的γ’相,碳化物在晶界上呈不连续的链状析出。
HY N90的工艺性能与要求
1、合金在锻造时易产生内裂,允许重锤打击。刚锭装炉温度不高于700℃,低温区域先预热20-30分钟,最终加热温度1150℃-1180℃,开锻温度不低于1050℃,终锻温度不低于950℃。
2、该合金的晶粒度平均尺寸与锻件的变形程度、终锻温度密切相关。
3、合金在固溶状态可进行惰性气体保护钨极电弧焊及闪光对焊。
