Feem ntau siv cov kev kho cua sov rau GR23 titanium yeeb nkab yog annealing, solid solution and aging treatment. Annealing yog tshem tawm cov kev ntxhov siab sab hauv, txhim kho plasticity thiab kev ruaj ntseg ntawm lub koom haum, txhawm rau kom tau txais kev ua tau zoo tag nrho. Feem ntau alloy thiab (+ ) alloy annealing kub yog xaiv nyob rau hauv (+ ) - → theem hloov taw tes hauv qab no 120 ~ 200 degree; kev daws teeb meem thiab kev laus kev kho mob yog los ntawm qhov kub thiab txias cheeb tsam ceev ceev, thiaj li yuav tau lub martensite 'theem thiab sub-stable theem, thiab ces nyob rau hauv nruab nrab kub cheeb tsam kub preservation kom lub sub-stable theem decomposition, tau lub theem los yog cov tebchaw thiab lwm yam me me diffuse theem thib ob ntawm qhov taw tes, thiaj li ua kom cov alloy kom ntxiv dag zog rau lub hom phiaj.
