Txoj kev loj hlob ntawm tsawg melting point alloys

Cov teb chaws txawv teb chaws muab qhov tseem ceeb rau kev tshawb fawb thiab kev siv cov hlau nplaum uas tsis tshua muaj melting point pwm alloys. Ntau lub dav hlau loj thiab tsheb tuam txhab lag luam muaj cov kws tshaj lij ua haujlwm hauv kev tshawb fawb txog kev tshawb fawb no. Txij li thaum xyoo 1970s, kev nce qib thiab kev siv cov hlau tsis tshua muaj melting point hlau pwm hauv Suav teb tau ua tiav kev loj hlob sai. Raws li kev txheeb cais, rau stamping qhov chaw xws li tsheb, tsheb laij teb npog thiab cov tawv nqaij dav hlau, uas tau hloov pauv sai thiab muaj cov duab nyuaj, kev siv cov pwm uas tsis tshua muaj melting alloy tuaj yeem ua rau lub voj voog tsim los ntawm 80% thiab txuag 70% mus rau 80% ntawm hlau.

Hauv pwm tsim, cov yam ntxwv ntawm cov ntawv nthuav tawm ntawm cov ntsiab lus me me alloys kuj tseem siv tau los ua kom haum rau kev sib sau ua ke convex thiab concave pwm. Qhov sib txawv tsis sib xws, tsis muaj kev ntxhov siab sab hauv yog tsim, thiab qhov zoo ntawm pwm tuaj yeem lav tau, tshwj xeeb tshaj yog rau cov tuag loj thiab nyuaj, nws cov nyhuv tseem ceeb dua. Cov pwm sib dhos yog ib qho yooj yim rau disassemble thiab kho, thiab qhov chaw ruaj tsuas yog xav tau kev siv tshuab ntxhib, uas txuag tau ntau ntawm cov neeg tsim khoom-teev, thiab cov hlau tuaj yeem rov qab siv dua, uas txo cov nqi tu.
