【摘要】：介紹了在鎳硅銅合金基礎(chǔ)上加入鋁及微量鈹元素,以提高其耐高溫性能,制備的CuNi2SiCrAl合金經(jīng)20%冷變形再時(shí)效的綜合性能尤其是高溫性能優(yōu)于未冷變形時(shí)效的狀態(tài);經(jīng)920℃固溶+20%冷變形+(435~465)℃×6h處理后,具有優(yōu)良的常溫、高溫力學(xué)性能及抗高溫軟化性能,各項(xiàng)性能指標(biāo)接近CuCo2BeZr合金,遠(yuǎn)高于CuNi2SiCr合金。
[Abstract]:The addition of aluminum and trace beryllium on the basis of nickel-silicon-copper alloy was introduced to improve its high temperature resistance. The comprehensive properties of the prepared CuNi2SiCrAl alloy after 20% cold deformation and re-aging, especially at high temperature, are superior to those of uncooled deformation aging. Treated with 920 鈩，
