Puas muaj kev sib raug zoo ntawm qhov hardness thiab lub zog ntawm Ti6AL4V titanium alloy? Lub hardness ntawm titanium alloy tsis siab, hardness ntawm ntshiab titanium yog HV280-300, hardness ntawm alloy yog HV280-340, lub zog thiab hardness ntawm steel cov ntaub ntawv muaj ib co kev sib raug zoo, tab sis hardness ntawm titanium. alloy tsis muaj dab tsi ua nrog lub zog.
Titanium alloy tsis suav tias yog ib qho nyuaj, nws tsuas yog lub zog siab.
Nrov nrov ntawm ob lub ntsiab lus: lub zog thiab hardness, lub zog yog hais txog lub peev xwm ntawm cov khoom los tiv thaiv deformation thiab tawg, hardness yog hais txog lub peev xwm ntawm cov khoom los tiv thaiv lwm cov ntaub ntawv rau hauv lawv tus kheej.
Titanium alloy hardness ntau dua li cov hlau hardened yog qis dua, kev kho nitriding yuav muaj qhov nce ntau, tab sis tseem tsis tuaj yeem piv rau silicon carbide, boron carbide thiab lwm cov ntaub ntawv hardness.
Thaum nws los txog rau cov khoom siv nyuaj tshaj plaws, peb yuav tsum hais txog Mr. Tian Yongjun ntawm Yanshan University, uas tau raug soj ntsuam raws li ib tus kws tshaj lij ntawm Suav Academy ntawm Kev Tshawb Fawb hauv xyoo 2017, thiab Mr. Tian pab neeg ua lub pob zeb diamond nano-twinned nrog lub hardness ( ntawm no yog qhov hardness tiag tiag) uas ncav cuag ob npaug ntawm cov pob zeb diamond ntuj, uas tam sim no paub tias yog cov khoom siv nyuaj tshaj plaws.
Titanium alloy yog tus cwj pwm los ntawm kev tiv thaiv corrosion, siab zog thiab tsawg ntom.
