Incoloy 909是Fe-Ni-Co基沉淀硬化型(xing)變形高(gao)(gao)(gao)溫(wen)(wen)合金(jin)，運用溫(wen)(wen)度在650℃以(yi)下。合金(jin)具有高(gao)(gao)(gao)強度、高(gao)(gao)(gao)冷(leng)熱疲倦抗力、低收縮(suo)系數和恒彈性模量，以(yi)及(ji)良好的熱加工塑性、冷(leng)成形和焊接(jie)性能。主(zhu)要(yao)產品有棒材(cai)、絲(si)材(cai)、板(ban)材(cai)、冷(leng)軋帶材(cai)和環形件等。

　　合(he)金已用(yong)于制(zhi)造渦(wo)(wo)輪發(fa)起機(ji)用(yong)環(huan)(huan)形零(ling)部(bu)件(jian)，如高壓(ya)壓(ya)氣機(ji)后機(ji)匣(xia)、承力(li)環(huan)(huan)、隔熱環(huan)(huan)、熄滅室(shi)封(feng)(feng)嚴(yan)環(huan)(huan)、蜂窩座(zuo)和(he)渦(wo)(wo)輪外(wai)環(huan)(huan)等(deng)；火箭發(fa)起機(ji)推力(li)熄滅室(shi)、排氣導管和(he)集流箱等(deng)。還推行(xing)應用(yong)至制(zhi)造槍管、炮用(yong)部(bu)件(jian)、玻(bo)璃-金屬封(feng)(feng)接(jie)資料、量具(ju)模(mo)具(ju)和(he)高壓(ya)氫氣環(huan)(huan)境用(yong)構(gou)件(jian)等(deng)。

　　由于此類(lei)合(he)金熱(re)收縮(suo)系數低、且(qie)隨溫度的變化率小，在(zai)很(hen)寬的溫度循環中可有(you)效地控制發起機部(bu)(bu)件和靜部(bu)(bu)件的間隙大(da)小，減(jian)少(shao)燃氣損失，節(jie)能降(jiang)耗，進(jin)步發起機效率，延長(chang)零部(bu)(bu)件壽(shou)命。在(zai)應用時，合(he)金外(wai)表(biao)可停止噴丸處置，以進(jin)步合(he)金的旋(xuan)轉彎曲(qu)高疲(pi)倦強度。
