Titanium Alloy Mechanical Properties
A amfani da zafin jiki ne 'yan ɗari digiri mafi girma fiye da aluminum gami, a cikin matsakaici zafin jiki na iya har yanzu kula da ake bukata ƙarfi, na iya zama 450 ~ 500 ℃ zafin jiki na dogon lokaci aiki wadannan biyu titanium gami a cikin kewayon 150 ℃ ~ 500 ℃. har yanzu yana da wani musamman high takamaiman ƙarfi, da aluminum gami a 150 ℃ takamaiman ƙarfi rage muhimmanci. The aiki zafin jiki na titanium gami iya isa 500 ℃, da aluminum gami ne kasa 200 ℃. Kyakkyawan nadawa lalata juriya.
Juriya na lalata na titanium ya fi na bakin karfe lokacin da yake aiki a cikin yanayi mai laushi da matsakaicin ruwan teku. Musamman juriya mai ƙarfi ga lalatawar rami, lalata acid da lalata damuwa; Yana da kyau kwarai juriya ga alkali, chloride, chlorinated Organic kaya, nitric acid, sulfuric acid, da dai sauransu Duk da haka, titanium yana da matalauta lalata juriya ga reductive oxygen da chromium gishiri kafofin watsa labarai.
Titanium alloy na iya kula da kaddarorin injinsa a ƙananan zafi da ƙarancin zafi. Titanium alloys tare da kyakkyawan aikin ƙarancin zafin jiki da ƙananan abubuwan tsaka-tsaki, kamar TA7, na iya kula da wani ɗan filastik a -253 ℃. Saboda haka, titanium gami kuma muhimmin abu ne mai ƙarancin zafin jiki. Ayyukan sinadarai na titanium yana da girma, kuma yanayin da ke cikin O, N, H, CO, CO₂, tururin ruwa, ammonia da sauran halayen sunadarai masu karfi. Lokacin da abun ciki na carbon ya fi 0.2%, zai samar da TiC mai wuya a cikin gami da titanium;
A mafi yawan zafin jiki, hulɗar tare da N zai kuma samar da TiN mai wuyar wuri; Sama da 600 ℃, titanium yana sha oxygen don samar da Layer hardening tare da babban taurin; Hakanan za'a samar da Layer embrittlement lokacin da abun ciki na hydrogen ya tashi. Zurfin wuya gaggautsa surface samar da iskar gas iya isa 0.1 ~ 0.15mm, da hardening mataki ne 20% ~ 30%. Dangantakar sinadarai na titanium shima babba ne, mai sauƙin samar da mannewa tare da farfajiyar gogayya.
Thermal conductivity na titanium λ = 15.24W / (mK) ne game da 1/4 na nickel, 1/5 na baƙin ƙarfe, 1/14 na aluminum, da thermal watsin kowane irin titanium gami ne game da 50% kasa da wancan. da titanium. A na roba modulus na titanium gami ne game da 1/2 na karfe, don haka ta rigidity ne matalauta, sauki nakasawa, bai kamata a yi da siririn sanda da bakin ciki-banga sassa, yankan aiki surface rebound girma ne babba, game da 2 ~ 3 sau. na bakin karfe, haifar da tsananin gogayya, adhesion, bonding lalacewa bayan kayan aiki surface.
