Hauv liaj teb xws li aerospace thiab kev tshawb nrhiav qhov chaw sib sib zog nqus, qhov yuav tsum muaj rau cov khoom siv yog cov tawv nruj. Cov ntaub ntawv yuav tsum tau ua lub teeb yuag, ua haujlwm, thiab muaj peev xwm hloov kho kom muaj qhov kub. Tsoos puab - cim xeeb alloys muaj kev ua tau tsawg tsawg - qhov kev tshawb fawb txog kev sib sib zog nqus - qhov chaw tshawb nrhiav thiab liquefied - roj cia. Qhov no ua rau cov kev tshawb fawb thiab kev txhim kho tshiab - hom khoom siv sai sai.
Pab pawg tshawb fawb tau ua hauv - Kev tshawb xyuas qhov tob thermodynamic thiab ua tib zoo tsim cov tshiab - hom alloy - ti75.25Al20R4.75 raws li theem kev kos duab. Lawv siv cov txheej txheem kub - kub ua kom ruaj khov - theem kev hloov kho microy, thiab cov duab neutractival, thiab cov duab digital diffraction (dic) thev naus laus zis. Hauv kev sim, cov alloy tau sai sai quenched tom qab kev kho cua sov siab - thiab loj - lub hauv paus muaj zog tau npaj, tso lub hauv paus txhim khu kev qha rau kev ntsuam xyuas cov cuab yeej siv.
Tus Tshiab - Hom Ti - Al - Cr Alloy tuaj yeem rov qab ua rau lub nroog muaj zog li 73% ntawm kev lag luam nick, uas yog sib npaug ntawm cov khoom siv titanium - raws li alloys. Nws qhov ceev yog 4.36 × 10³, thiab nws lub zog tshwj xeeb yog qhov siab li 185 × 105, uas yog ntau dua ob zaug uas yog ib zaug ntawm lub teeb ci ntsa iab - nco alloys. Txawm tias ntau qhov xav tsis thoob, no alloy tswj super - elasticity nyob rau hauv ib tug ntau qhov rai ntawm 396 k, uas yog tsib zaug ntawm Nickel - Titanium alloys. Nws cov super - Elasticity keeb kwm los ntawm Martensitic theem hloov pauv ntawm B2 txog B19, thiab nws qhia tau qhov tsis txaus siab hauv Shear zog hauv kev ua kom muaj zog.
Nws tuaj yeem pom meej meej los ntawm daim duab uas tus Super - Elastic kub ntau yam hauv lub ntiaj teb, Mars, thiab lub hli. Piv nrog lwm yam duab - cim xeeb alloys, nws kuj muaj qhov zoo nyob rau hauv cov nqe lus ntawm ntom thiab super - elastic ua haujlwm kub ntau.
Nws yog zoo li lub hnub qub tshiab tshiab, ci ntsa iab nrog lub teeb tshwj xeeb hauv cov ntaub ntawv tshawb fawb thiab coj cov kev coj ua tshiab ntawm kev txhim kho yav tom ntej.
