Puas yog titanium nyuaj? titanium nyuaj npaum li cas?
Hardness yog ib qho ntawm feem ntau siv cov ntsuas rau kev ntsuam xyuas cov khoom ntawm cov khoom hlau. Lub ntsiab ntawm hardness yog lub peev xwm ntawm cov khoom siv los tiv thaiv lub siab ntawm lwm yam khoom nyuaj. Nws yog dav siv hauv kev tshuaj xyuas kev ua haujlwm hlau, kev kho cua sov txheej txheem kev saib xyuas zoo thiab kev tsim cov ntaub ntawv tshiab. Daim ntawv thov teb ntawm titanium hlau yog dav heev, los ntawm aerospace mus rau cov khoom siv kho mob, los ntawm cov khoom ua si rau cov hniav nyiaj hniav kub, yuav luag txhua qhov chaw. Yog li, titanium nyuaj? titanium nyuaj npaum li cas?
Qhov tseeb, hardness tsis yog tib qho kev ntsuas rau ntsuas lub zog ntawm cov khoom. Hardness feem ntau yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv lub zos siab deformation, qhab nia lossis khawb. Txawm hais tias lub hardness ntawm titanium hlau tsis zoo li lwm yam hlau xws li hlau los yog pob zeb diamond, nws lub zog tshwj xeeb thiab toughness muab nws tshwj xeeb zoo. Nyob rau hauv cov qauv titanium thiab titanium alloy bar qauv, xws li GB / T 2965-2007, GJB2218A-2008, thiab GJB1538A-2008, hardness tsis yog siv raws li kev lees paub. Txawm li cas los xij, nyob rau hauv lub cav thiab forging cov qauv nrog cov kev xav tau siab dua, xws li GJB2744A-2007 thiab GJB494A-2008, hardness yog xav tau raws li qhov kev lees paub, feem ntau sim Rockwell hardness lossis Brinell hardness.

Lub hardness ntawm titanium hlau feem ntau yog tshwm sim nyob rau hauv nws lub zog siab thiab zoo heev toughness. Cov hlau no tuaj yeem tiv taus siab heev thiab nro thaum tuav zoo elasticity. Qhov no ua rau cov hlau titanium muaj qhov zoo tsis tuaj yeem hloov tau hauv kev tsim cov dav hlau ua haujlwm siab, lub dav hlau thiab cov khoom siv tsheb.
