Nigute uburyo bwo gutunganya ubushyuhe busanzwe bwa beryllium bronze ikora

Umuringa wa Berylliumni ibisanzwe gusaza imvura igabanya imbaraga.Ubusanzwe uburyo bwo kuvura ubushyuhe bwumuringa ukomeye wa beryllium nugukomeza ubushyuhe kuri 760-830 ℃ mugihe gikwiye (byibuze 60min kuri buri sahani yuburebure bwa 25mm), kugirango atom beryllium ikemuke neza. matrike y'umuringa hanyuma igakora isura yibanze ya cubic lattice α Icyiciro kirenze igisubizo gikomeye.Noneho, kubika ubushyuhe kuri 320 ~ 340 ℃ kuri 2 ~ 3h kugirango urangize inzira yimvura ishonga, ikora γ ′ Icyiciro (CuBe2 metastable phase).Iki cyiciro gihujwe numubiri wababyeyi, bikavamo umurima uhangayitse no gushimangira matrix.

Nigute uburyo bwo gutunganya ubushyuhe busanzwe bwa beryllium bronze ikora

Ubusanzwe uburyo bwo kuvura ubushyuhe bwa beryllium bronze ni ugukomeza ubushyuhe kuri 900 ~ 950 ℃ mugihe runaka kugirango urangize igisubizo gikomeye, hanyuma ugumane ubushyuhe kuri 450 ~ 480 ℃ kuri 2 ~ 4h kugirango umenye guseswa. inzira yimvura.Bitewe no kongeramo cobalt cyangwa nikel nyinshi muri alloy, ibice bikwirakwiza imbaraga ni ibice bivangavanze bigizwe na cobalt cyangwa nikel na beryllium.Kugirango turusheho kunoza imbaraga zumusemburo, ibinyomoro akenshi bikonje bikorerwa kurwego runaka nyuma yo gukemura ubushyuhe bwumuti ndetse na mbere yo kuvura ubushyuhe bwashaje, kugirango tugere ku ngaruka zishimangira imbaraga zimirimo ikonje no gukomera kwimyaka.Imikorere yayo ikonje muri rusange ntabwo irenga 37%.Gutunganya ubushyuhe bwumuti bigomba gukorwa nuwabikoze.Umukoresha azakubita igisubizo cyubushyuhe buvuwe hamwe nubukonje bukonje mubice, hanyuma akore ubuvuzi bwogusaza kugirango abone imbaraga nyinshi zimpeshyi.

Mu myaka yashize, Ubushinwa nabwo bwateje imbere umurongo hamwe no kuvura ubushyuhe bwashaje byarangiyeabakora umuringa wa beryllium, zishobora gukubitwa ibice nabakiriya.Umuringa wa beryllium umaze gukorerwa inzira zitandukanye, amabaruwa ya leta ya alloy mu Burayi no muri Amerika ni: Ikimenyetso cyo gukemura igisubizo gihamye leta.Amavuta ari muburyo bworoshye kandi byoroshye gushingwa kashe.Irakeneye gukora ubukonje bukora cyangwa gusaza bikomeza kuvura.H igereranya akazi gakomeye leta (birakomeye).Fata urupapuro rukonje nk'urugero, 37% by'impamyabumenyi y'akazi ikonje ni ibintu bikomeye (H), 21% by'impamyabumenyi y'akazi ikonje ni kimwe cya kabiri gikomeye (1 / 2H), naho 11% by'impamyabumenyi ikonje ni 1 / 4 bigoye (1 / 4H).Abakoresha barashobora guhitamo ibyoroshye byoroshye kandi bigoye ukurikije ingorane zuburyo bwibice bigomba gukubitwa.T bivuga kuvura ubushyuhe nyuma yo gusaza.Niba inzira yo guhindura no gusaza gushimangira byimazeyo, leta yayo ihagarariwe na HT.
