Mbere, abakiriya benshi babajije bagenzi babo bo mu ishami ry’ikoranabuhanga rya RSM ibijyanye na titanium. Noneho, ndashaka kuvuga mu ncamake ingingo zikurikira kuri wewe kubijyanye nicyuma cyitwa titanium alloy ikozwe. Nizere ko bashobora kugufasha.
Umuti wa Titanium ni umusemburo wakozwe muri titanium nibindi bintu.
Titanium ni kristu ya heterogeneous kristal, ifite aho ishonga 1720 ℃. Iyo ubushyuhe buri munsi ya 882 ℃, iba ifite ibikoresho byegeranye byegeranye cyane, bita α Titanium; Ifite umubiri wubatswe hejuru ya 882 ℃, yitwa β Titanium. Kwifashisha ibintu bitandukanye biranga imiterere ibiri yavuzwe haruguru ya titanium, ibintu bikwiye bivangwa byongeweho kugirango buhoro buhoro bihindure buhoro buhoro ubushyuhe bwabyo hamwe nibirimo kugirango ubone titanium ivanze hamwe nuburyo butandukanye. Ku bushyuhe bwicyumba, amavuta ya titanium afite ubwoko butatu bwububiko bwa matrix, kandi titanium alloys nayo igabanijwemo ibyiciro bitatu bikurikira: α Alloy (α + β) Alloy na β Alloy. Mu Bushinwa, herekanwa na TA, TC na TB.
α titanium
Ni α Icyiciro kimwe kivanze kigizwe nigisubizo gikomeye ni α Icyiciro, imiterere ihamye, irwanya kwambara cyane kuruta titanium yera, irwanya okiside ikomeye. Munsi yubushyuhe bwa 500 ℃ ~ 600 ℃, iracyakomeza imbaraga zayo no guhangana n’ibikurura, ariko ntibishobora gushimangirwa no kuvura ubushyuhe, kandi ubushyuhe bw’icyumba bwayo ntabwo buri hejuru.
ani titanium
Ni β Icyiciro kimwe kivanze kigizwe nicyiciro gikomeye gikemura gifite imbaraga zisumba izindi zitavura ubushyuhe. Nyuma yo kuzimya no gusaza, amavuta arushaho gukomera, kandi ubushyuhe bwicyumba burashobora kugera kuri 1372 ～ 1666 MPa; Nyamara, ubushyuhe bwumuriro burakennye kandi ntibukwiriye gukoreshwa mubushyuhe bwinshi.
α + β titanium
Nibice bibiri bivanze hamwe nibintu byiza byuzuye, imiterere myiza yimiterere, gukomera kwiza, plastike hamwe nubushyuhe bwo hejuru. Irashobora gukoreshwa mugutunganya umuvuduko ushushe, kuzimya no gusaza kugirango ushimangire amavuta. Imbaraga nyuma yo kuvura ubushyuhe ziri hejuru ya 50% ~ 100% kurenza iyo nyuma ya annealing; Imbaraga z'ubushyuhe bwo hejuru, zishobora gukora kuri 400 ℃ ~ 500 ℃ igihe kirekire, kandi ituze ryumuriro ntiri munsi ya α Titanium.
Mubintu bitatu bya titanium α Titanium alloys na α + β Titanium; α Titanium alloy ifite imashini nziza, α + P Umuti wa Titanium ufata umwanya wa kabiri, β Umuti wa Titanium urakennye. α Kode ya titanium alloy ni TA, β Kode ya titanium alloy ni TB, α + β Kode ya titanium alloy ni TC.
Amavuta ya Titanium arashobora kugabanywamo ibinyobwa bidashobora kwihanganira ubushyuhe, imbaraga zikomeye cyane, imiti irwanya ruswa (titanium molybdenum, titanium palladium alloys, nibindi), ibishishwa byubushyuhe buke hamwe nudukoryo twihariye (ibikoresho byo kubika titanium fer hydrogène hamwe na titanium nikel yibuka ) ukurikije ibyo basabye.
Kuvura ubushyuhe: titanium alloy irashobora kubona ibyiciro bitandukanye hamwe nimiterere muguhindura uburyo bwo gutunganya ubushyuhe. Muri rusange abantu bemeza ko microstructure nziza iringaniye ifite plastike nziza, ituze ryumuriro nimbaraga zumunaniro; Imiterere ya acicular ifite imbaraga zo guturika cyane, imbaraga zo kunyerera no gukomera kuvunika; Uruvangitirane ruvanze kandi rwa acicular rufite imikorere myiza yuzuye
