Isakhiwo sokukhulisa okuphansi senduku ye-titanium ye-GR23 | Uhlu lweziphambeko + Imigomo yokwamukelwa

Ku-cross-section ye-GR23 titanium rod, lelo phatheni akulona umhlobiso. Isakhiwo se-low-magnification asihlangani nezinga. Ungaxhumanisi imigqa lapho kufakwa emzimbeni. Yisakhiwo se-macroscopic tissue. Ngokwe-GB/T 516, iyindlela ephelele ye-cross-sectional ngemva kokugqwala kusetshenziswa iso lenyama noma nge-magnification engadluli izikhathi ezingama-20, ngaphandle kokucwiliswa ku-optical microscope. Ku-medical titanium 6AL4V ene-GR23 asm f 136, i-low-magnification ihilela izinto ezintathu: okokuqala, ukukhomba izinkinga ze-metallurgical defects ezibulalayo njenge-cracks, pores, porosity, noma ama-inclusions e-metal noma e-non-metallic, kanye nokwehlukaniswa kwe-beta plate composition. Lezi zithathwa ngokuqondile njenge-scrap ku-cross-section ngokwe-GB/T 13810 kanye ne-asm f 136. Okwesibili, hlola ukuqhubeka kwemigqa ye-forging flow. Uma imigqa ye-forging iphazamisekile noma isonteke ngokungahleliwe, kusho ukuthi indlela yamandla iziphazamisele yona. Okwesithathu, hlola usayizi wangempela we-beta energy kanye nokulingana kwesakhiwo. Uma i-beta phase ingahlukanisiwe futhi i-alpha phase inqwabelene, ngisho nokuhlolwa kwe-high-magnification akukwazi ukuyibuyisela. Ukuthathwa kwesampula kuthathwa kokubili ngokuqondile nangokuma. Indawo yokusika kufanele igaywe ibe ngaphansi noma ilingane ne-1.6 micrometers. I-water solution cold pool pure water rinse dry body flow diagram asTm system titanium alloy ayisebenzisi i-E381, ngoba eyensimbi. Indlela ehambisanayo ilandela i-F136 macro evaluation kanye ne-E340 macro reference acceptance bottom line. I-bottom back ayivunyelwe ukuba noma yikuphi ukuqhekeka okubonakalayo, ama-pores, ama-inclusions, noma izingxenye ze-flow line ezingajwayelekile. Ama-beta spots kanye nezindawo ezikhanyayo-nomnyama, kanye ne-knee band. Kusukela ku-Zone 1, ukwahlulelwa kabusha kwe-high-magnification kufanele kwenziwe. Akuvunyelwe ukuhlola. Kubukeka kusengcono. I-low-magnification yinqubo yokufakwa.
