4J42yog cov hlau-npib tsib xee khaws cov expansion alloy, feem ntau muaj ntawm cov hlau (FE) thiab Nickel (NI), nrog rau cov ntsiab lus npib tsib) txog 42%. Tsis tas li ntawd, nws tseem muaj cov nqi me me xws li silicon (si), manganese (mn), carbon (p). Qhov tshwj xeeb no kev sib xyaw ua haujlwm muab nws ua tau zoo heev.

Thaum ntxov xyoo pua 20, nrog nce ntawm hluav taws xob thev naus laus zis, cov khoom lag luam thiab lwm yam kev tshawb fawb tau pib tshawb cov ntaub ntawv tshwj xeeb nrog cov khoom tshwj xeeb. Raws li cov hlau-npib tsib xee-cobalt alloy, kev tshawb fawb thiab kev txhim kho ntawm 4J42 nthuav dav alloy yog kom tau raws li cov kev xav tau ntawm cov kev xav tau kev ua tau zoo. Los ntawm tsis tu ncua kho cov ntsiab lus ntawm cov ntsiab lus xws li npib tsib, thiab cov neeg kwv yees li tau txiav txim siab, thiab cov neeg kwv yees kwv yees li ntawm 4J42

Nrog kev nce qib nruam ntawm kev tshawb fawb thiab thev naus laus zis, kev xav tau kev ua haujlwm rau 4J42 nthuav tawm alloy kuj tseem tau txais siab dua thiab siab dua. Cov kws tshawb nrhiav txuas ntxiv txhim kho kev ua haujlwm ntawm 4j42 alloy los ntawm kev txhim kho cov txheej txheem ntau lawm thiab ua kom zoo tagnrho muaj pes tsawg leeg. Piv txwv li, kev siv ntau tshaj plaws smelting tshuab thiab kev siv thev naus laus zis tau txhim kho cov kev cuam tshuam thiab kev sib txawv, thiab ntxiv txo qhov cuam tshuam ntawm kev ua haujlwm ntawm cov alloy. Nyob rau tib lub sijhawm, cov txheej txheem kev tshav kub kub thiab cov txheej txheem vuam ntawm 4J42 cov txheej txheem tsim nyog tau tsim los txhim kho kev ua haujlwm thiab siv kev ua tau zoo ntawm cov alloy.

Nyob rau hauv xyoo tas los, nrog kev txhim kho sai ntawm elotics, aerospace, kho mob thiab lwm daim teb, qhov kev xav tau txuas ntxiv ntxiv, thiab daim ntawv thov tau txuas ntxiv nthuav dav. Hauv kev thaj teb hluav taws xob, nrog kev txhim kho txuas ntxiv ntawm cov khoom sib xyaw, semiconductor cov cuab yeej, thiab lwm yam. 4J42 alloy tau dhau los ua cov khoom tseem ceeb hauv kev ua haujlwm hauv hluav taws xob vim nws qhov kev nthuav dav thermal nthuav dav thiab kev ua haujlwm vuam.

Nrog kev nce qib nruam ntawm cov thev naus laus zis ntau lawm, yuav tau them rau cov ntsiab lus ntawm cov neeg tawg nkoj tom ntej. Qhov no yuav txuas ntxiv qhov kev ua tau zoo ntxiv ntawm cov alloy, txo kev ua tau zoo los ntawm kev ntseeg siab, thiab txhim kho kev ntseeg tau ntawm cov alloy hauv cov ntawv thov siab. Piv txwv li, hauv kev ntim khoom hluav taws xob hauv hluav taws xob, siab dua 30042 alloy tuaj yeem ua kom lub sijhawm ntev ruaj khov thiab ua haujlwm siab ntawm cov hluav taws xob.
