Cov yas yog nkig. Puas muaj feem xyuam rau kev txhaj tshuaj molding?

Yog lawm, qhov brittleness ntawm cov yas tuaj yeem cuam tshuam nrog kev txhaj tshuaj molding, vim tias cov txheej txheem txhaj tshuaj tuaj yeem cuam tshuam rau lub cev ntawm cov khoom yas. Kev txhaj tshuaj molding yog txheej txheem tsim khoom uas cov khoom siv yas molten yog txhaj rau hauv pwm nyob rau hauv siab siab thiab ces txias los ua ib feem. Cov txheej txheem ua kom txias tuaj yeem ua rau cov khoom siv yas kom txo qis thiab kev cog lus, uas tuaj yeem tsim kev ntxhov siab thiab sab hauv cov khoom siv. Yog tias cov txheej txheem txias tsis tau tswj xyuas kom zoo, cov kev ntxhov siab sab hauv tuaj yeem ua rau cov yas ua nkig thiab ua rau tawg lossis tawg.

Lwm yam tseem ceeb uas tuaj yeem ua rau lub brittleness ntawm cov yas hauv kev txhaj tshuaj molding muaj xws li kev xaiv cov khoom siv yas, kev ua haujlwm tsis zoo (xws li kub thiab siab), thiab tsim pwm nws tus kheej. Piv txwv li, yog tias cov khoom siv yas tsis zoo qhuav los yog muaj impurities, qhov no tuaj yeem cuam tshuam rau nws cov khoom siv kho tshuab thiab ua rau nws nkig. Ib yam li ntawd, yog tias cov txheej txheem ua tsis tau zoo rau cov khoom siv tshwj xeeb thiab pwm tsim, qhov no tuaj yeem tsim qhov tsis xws lossis tsis muaj zog hauv qhov ua tiav uas tuaj yeem ua rau brittleness.

Txhawm rau txo qhov kev pheej hmoo ntawm brittleness hauv cov khoom yas uas tsim los ntawm kev txhaj tshuaj molding, nws yog ib qho tseem ceeb uas yuav tsum ua tib zoo tswj cov txheej txheem kev ua haujlwm, xaiv cov khoom siv yas zoo, thiab tsim pwm uas txo cov kev ntxhov siab thiab strain ntawm cov khoom. Tsis tas li ntawd, kev kho tom qab ua tiav xws li annealing lossis kev ntxhov siab tuaj yeem siv los txo cov kev ntxhov siab hauv cov khoom siv thiab txhim kho nws cov khoom siv kho tshuab.
