INCONEL 625 (UNS N06625 / W.Nr.2.4856)

Kufotokozera Kwachidule:

Aloyi 625 (UNS N06625) ndi aloyi ya nickel-chromium-molybdenum yokhala ndi niobium yowonjezerapo. Kuwonjezeredwa kwa molybdenum kumagwira ntchito ndi niobium kuti kulimbikitse matrix ya aloyi, kupereka mphamvu yayikulu popanda chithandizo chowonjezera kutentha. Aloyiyo imalimbana ndi malo osiyanasiyana owononga ndipo imalimbana bwino ndi dzimbiri lobowoka ndi ming'alu. Aloyi 625 imagwiritsidwa ntchito pokonza mankhwala, kupanga mafuta ndi gasi m'mlengalenga ndi m'madzi, zida zowongolera kuipitsidwa kwa mpweya ndi ma reactor a nyukiliya.

Chiyambi cha Zamalonda

Inconel 625 imapangidwa makamaka ndi nickel (58%), chromium (20-23%), molybdenum (8-10%), manganese (5%), ndi chitsulo (3-5%). Ilinso ndi titaniyamu, aluminiyamu, cobalt, sulfure, ndi phosphorous. Kuphatikiza kwa zinthuzi kumapangitsa kuti ikhale yolimba ku oxidation ndi dzimbiri pa kutentha kwambiri.

Alloy 625 ndi alloy ya nickel-chromium yomwe imagwiritsidwa ntchito chifukwa cha mphamvu zake zapamwamba, kupangika bwino kwambiri komanso kukana dzimbiri. Kutentha kwa ntchito kumatha kuyambira pa cryogenic mpaka 980°C (1800°F). Mphamvu ya alloy 625 imachokera ku mphamvu yolimba ya molybdenium ndi niobium pa nickel-chromium matrix yake.

Motero mankhwala oletsa kuuma kwa mvula sakufunika. Kuphatikiza kwa zinthuzi kumathandizanso kuti zinthu zisawonongeke kwambiri m'malo osiyanasiyana owononga komanso kutentha kwambiri monga okosijeni ndi carburization.

Inconel alloy 625 ndi alloy yomwe anthu ambiri amaikonda chifukwa cha mphamvu zake zodabwitsa zamakina. Ili ndi mphamvu yabwino kwambiri yotopa, mphamvu yokoka, komanso kuphulika kwakukulu kwa kugwedezeka pansi pa kutentha kofika 1500F. Kuphatikiza apo, kukana kwake kupsinjika kwa dzimbiri komanso kukana okosijeni kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kwambiri. UNS N06625 imaperekanso kusinthasintha kwapamwamba komanso kupangika bwino poyerekeza ndi zida zina zambiri zofanana - zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri cha zigawo zomwe zimafunika kupangidwa mozama kapena kulumikizidwa movutikira. Mwachidule, Inconel 625 ndi yankho lamphamvu kwambiri komanso losinthasintha m'dziko lopikisana la alloy achitsulo.

Khalidwe ndi kapangidwe ka mankhwala a kalasi iyi zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mu nyukiliya ndi ndege.
