【摘要】：采用泡沫陶瓷過(guò)濾器對(duì)K4169鎳基高溫合金二次返回料進(jìn)行凈化處理,測(cè)試了合金的室溫力學(xué)性能和中溫持久壽命。結(jié)果表明,采用多塊過(guò)濾器組合凈化K4169合金二次返回料,顯著提高了合金的力學(xué)性能,尤其是中溫持久壽命,在650℃/620 MPa下的持久壽命從0.17h提高到20.5h以上。結(jié)果表明,過(guò)濾凈化可有效濾除合金中10μm以上的夾雜物,顯著減少顯微縮松缺陷。
[Abstract]:The secondary return material of K4169 nickel-base superalloy was purified by foam ceramic filter. The mechanical properties at room temperature and the rupture life at moderate temperature of the alloy were tested. The results show that the mechanical properties of K4169 alloy are significantly improved by using multi-block filter combination to purify the secondary return material, especially at moderate temperature, and the rupture life at 650 鈩，
