Kub sib sau tshuab ntawm titanium alloy
Tam sim no, raws li kev ua haujlwm kub thaum cov yas deformation tshwm sim, hlau-yas deformation tuaj yeem muab faib ua qhov txias txias (hauv qab qhov kub ntawm recrystallization yam tsis muaj txheej txheem rov qab), thermal deformation (siab dua qhov kub ntawm recrystallization), thiab sov deformation (nruab nrab ntawm ob sab saum toj). ). Nyob rau hauv cov txheej txheem ntawm titanium alloy los xij, kub sib sau yog cov paub tab thiab siv dav siv tshuab, feem ntau suav nrog hluav taws xob cua sov cua sov, cua sov ua haujlwm, thiab induction cua sov. Titanium alloy kub txoj kev siv tshuab yog los ua kom sov cov ntawv titanium alloy rau qhov tsim nyog qhov kub thiab txias, thiab siv cov yas deformation softening yam ntxwv ntawm titanium alloy ntawm qhov kub thiab txias (lub zog tawm los txo qis thiab elongation nce) kom paub txog kev tsim cov titanium alloy qhov chaw. . Tam sim no, kev tshawb fawb ntawm titanium alloy kub sib sau ua ke feem ntau tsom rau kev tsim cov cuab yeej, kev tsim cov txheej txheem, microstructure, formability, thiab kev txwv.
Pulse tam sim no pab tsim ntawm titanium alloy
Txij li thaum xyoo 1990, cov kws tshawb fawb los ntawm ntau lub teb chaws tau ua ntau qhov kev sim thiab kev tshawb fawb theoretical ntawm electro plasticity ntawm Al, Ti, Ni, Cu, thiab lwm yam ntaub ntawv, thiab muab tso rau hauv ib tug series ntawm cov kev xav ntawm lub electro plasticity nyhuv. Piv nrog rau Joule tshav kub nyhuv ntawm ib txwm thermal pab tsim, tam sim no pab txoj kev siv tshuab kuj muaj ib tug ntshiab electro-yas nyhuv, daim tawv nqaij nyhuv, sib nqus compression nyhuv, thiab hais txog, uas yog, lub multi-field coupling nyhuv ntawm hluav taws xob thermal quab yuam, uas muaj kev cuam tshuam rau microstructure thiab mechanical zog ntawm cov ntaub ntawv. Nyob rau tib lub sijhawm, cov txheej txheem kev pabcuam tam sim no muaj qhov zoo ntawm cov cuab yeej siv tsis tshua muaj qhov nyuaj, ceev cua sov tus nqi, siab electro thermal conversion tus nqi, thiab siab kub uniformity. Nws muaj txoj kev loj hlob dav dav hauv kev ua cov yas uas nyuaj rau kev tsim cov hlau ntawm chav tsev kub thiab xav tias yuav siv rau hauv kev khoov, kos duab, dov, bulging, kev sib sau ua ke, thiab lwm yam txheej txheem.
