Cov khoom siv ntawm cov cuab yeej txiav alloy feem ntau yog cov hlau tawv tawv, uas yog cov khoom siv hlau ua los ntawm cov khoom siv tawv tawv ntawm cov hlau refractory thiab cov hlau sib txuas los ntawm cov txheej txheem hmoov metallurgy. Hard alloys muaj cov khoom zoo heev xws li siab hardness, hnav tsis kam, zoo zog thiab toughness, kub tsis kam, corrosion kuj, thiab lwm yam., tshwj xeeb tshaj yog muaj peev xwm tswj tau siab hardness thiab hnav kuj txawm nyob rau hauv high kub. Cov khoom siv no yog siv dav hauv kev tsim cov cuab yeej txiav, xws li cov cuab yeej tig, milling cutters, planers, laum khoom, thiab lwm yam. Nws yog tsim rau kev txiav hlau cam khwb cia hlau, non-ferrous hlau, yas, tshuaj fibers, graphite, iav, pob zeb. thiab cov hlau zoo tib yam, nrog rau nyuaj rau cov khoom siv xws li cov hlau tsis muaj cua sov, cov hlau tsis muaj steel, siab manganese hlau, thiab cov cuab yeej hlau.
Cov khoom siv ntawm cov cuab yeej hard alloy txiav muaj xws li siab hardness, hnav tsis kam, zoo zog thiab toughness, uas ua rau lawv zoo heev thaum siv rau kev txiav hauv kev tsim khoom. Cov cuab yeej hard alloy txiav tso cai rau kev txiav ceev 5-10 lub sij hawm siab dua li cov cuab yeej siv high-speed steel, tab sis muaj qis dua dabtsi yog khoov lub zog thiab cuam tshuam rau lub zog, ua rau lawv tsim nyog rau kev ua haujlwm tshwj xeeb thiab cov khoom siv.
Tsis tas li ntawd, cov cuab yeej txiav hlau kuj muaj xws li ib hom hlau uas ntxiv cov ntsiab lus alloying xws li chromium, molybdenum, tungsten, thiab vanadium los ntawm cov cuab yeej carbon steel los txhim kho hardenability, toughness, hnav tsis kam, thiab kub tsis kam. Nws yog tsuas yog siv rau kev tsim cov cuab yeej ntsuas, cov cuab yeej txiav, thiab lwm yam Alloy txiav lub taub hau yog tsim rau txoj kev ntxhib, kev npaj ntxhib, ntxhib milling, thiab lwm yam. cov ntaub ntawv tsis yog xim hlau.
