Incoloy 909是Fe-Ni-Co基沉淀硬化型變形高(gao)溫合(he)金(jin)，運用溫度在650℃以下。合(he)金(jin)具(ju)有(you)高(gao)強(qiang)度、高(gao)冷熱(re)疲倦抗(kang)力、低收縮系數(shu)和恒彈(dan)性(xing)模(mo)量，以及良好的(de)熱(re)加工塑(su)性(xing)、冷成形和焊接性(xing)能(neng)。主要產品有(you)棒(bang)材、絲材、板材、冷軋帶材和環(huan)形件等。

　　合金已用(yong)于制造渦(wo)輪發(fa)起機用(yong)環形零部件(jian)，如(ru)高壓壓氣(qi)機后機匣(xia)、承力環、隔熱環、熄(xi)滅(mie)室封嚴環、蜂窩座和(he)渦(wo)輪外環等(deng)；火箭發(fa)起機推(tui)力熄(xi)滅(mie)室、排氣(qi)導(dao)管和(he)集流箱等(deng)。還(huan)推(tui)行應用(yong)至制造槍管、炮(pao)用(yong)部件(jian)、玻璃-金屬封接資料、量(liang)具模具和(he)高壓氫氣(qi)環境用(yong)構(gou)件(jian)等(deng)。

　　由于此類合金(jin)熱收縮系數低(di)、且隨溫(wen)度的變化率(lv)小，在很寬的溫(wen)度循環中(zhong)可(ke)有效地控制發起機(ji)部(bu)(bu)件和靜部(bu)(bu)件的間隙大(da)小，減(jian)少燃氣損失(shi)，節(jie)能降耗，進(jin)(jin)步發起機(ji)效率(lv)，延長零部(bu)(bu)件壽命(ming)。在應用(yong)時，合金(jin)外表可(ke)停止噴丸(wan)處置，以進(jin)(jin)步合金(jin)的旋(xuan)轉彎曲高疲倦強度。

　　熱處置制度制度A:965-1010℃±10℃保(bao)溫(wen)(wen)1小(xiao)(xiao)(xiao)(xiao)時(shi)，空(kong)冷(leng)(leng)或(huo)(huo)快冷(leng)(leng)+720℃保(bao)溫(wen)(wen)8小(xiao)(xiao)(xiao)(xiao)時(shi)以每小(xiao)(xiao)(xiao)(xiao)時(shi)55℃降溫(wen)(wen)至(zhi)620℃保(bao)溫(wen)(wen)8小(xiao)(xiao)(xiao)(xiao)時(shi)，空(kong)冷(leng)(leng)制度B:965-1010℃±10℃保(bao)溫(wen)(wen)1小(xiao)(xiao)(xiao)(xiao)時(shi)，空(kong)冷(leng)(leng)或(huo)(huo)快冷(leng)(leng)+745℃保(bao)溫(wen)(wen)4小(xiao)(xiao)(xiao)(xiao)時(shi)以每小(xiao)(xiao)(xiao)(xiao)時(shi)55℃降溫(wen)(wen)至(zhi)620℃保(bao)溫(wen)(wen)4小(xiao)(xiao)(xiao)(xiao)時(shi)，空(kong)冷(leng)(leng)制度C:980℃±10℃保(bao)溫(wen)(wen)1小(xiao)(xiao)(xiao)(xiao)時(shi)，空(kong)冷(leng)(leng)或(huo)(huo)快冷(leng)(leng)+745℃保(bao)溫(wen)(wen)4小(xiao)(xiao)(xiao)(xiao)時(shi)以每小(xiao)(xiao)(xiao)(xiao)時(shi)55℃降溫(wen)(wen)至(zhi)620℃保(bao)溫(wen)(wen)4小(xiao)(xiao)(xiao)(xiao)時(shi)，空(kong)冷(leng)(leng)。
