Kampfgrupp's R & D Pab Pawg Ua tiav hauv Titanium Alloy Txhim Kho

Yang Rui, tus thawj coj ntawm lub koom haum ntawm Hlau, Suav Academy ntawm Sciences (tom qab no hu ua "Institute of Metals") thiab tus thawj coj ntawm Titanium Alloy Research Department, coj cov kws tshawb fawb Lei Jiafeng thiab Ma Yingjie los lees txais lub luag haujlwm hnyav ntawm kev tsim kho tshiab. titanium alloy. Txhawm rau ua kom tiav 10,000-meter manned submersible project, Yang Rui pab neeg yuav tsum xub daws cov teeb meem khoom siv, uas yog ib txoj hauj lwm nyuaj uas tsis tuaj yeem zam los yog shirked. Titanium alloy cov ntaub ntawv muaj "qhov loj me", uas yog, qhov loj dua qhov loj thiab tuab, qhov nyuaj dua los xyuas kom meej qhov ruaj khov ntawm cov khoom sib xws thiab cov khoom siv kho tshuab. Thiab qhov no yog daim ntawv thov ntawm huab cua-siab ib puag ncig nyob rau hauv lub hiav txwv sib sib zog nqus yuav tsum hla lub barrier.

Cov kws tshawb fawb Asmeskas tau kawm txog qhov teeb meem no thiab pom qhov laj thawj rau qhov tsis zoo weldability ntawm Ti2222: qhov titanium alloy no yuav tsim ib qho kev sib xyaw hauv cov nplej thaum annealed. Ib tug ntawm Yang Rui cov tub ntxhais kawm tau koom nrog kev tshawb fawb hlau ntawm National Institute for Materials Research hauv Nyij Pooj, thiab cov tub ntxhais kawm no tau tshawb fawb heev. Nws tshawb pom los ntawm kev sim hais tias yog tias cov hlau muaj nuj nqis me ntsis ntxiv rau titanium alloy, cov khoom siv plasticity yuav zoo dua. Tsis tas li ntawd, Yang Rui nws tus kheej, thaum pab lub tuam txhab British engine manufacturing tuam txhab los tsim titanium alloy hniav, nrhiav pom tias ib qho ntawm cov alloys ntawm cov hniav yuav muaj cov hlau molybdenum.

Nyob rau tib lub sijhawm, ib tug tswv cuab ntawm pab pawg tau pom ib tus kws tshawb fawb txawv teb chaws tham txog qhov teeb meem zoo sib xws hauv daim ntawv luam tawm. Yang Rui, Lei Jiafeng thiab lwm tus tau lees paub ntxiv tias qhov kev tawg tuaj yeem pom tau los ntawm kev tshem tawm "theem teeb meem" ntawm cov khoom siv.

Los ntawm kev sib txuas tag nrho cov ntsiab lus no, Yang pab neeg thaum kawg tau xaus lus: ntxiv cov hlau palladium thiab hlau molybdenum, los yog cov ntsiab lus zoo sib xws rau Ti2222, tuaj yeem ua rau cov ntsiab lus ntawm qee qhov kev xav tau. Tom qab kev tshawb fawb, lawv thaum kawg tau los nrog ib txoj kev npaj tshiab: sib tov titanium daim txhuam cev thiab vanadium ua ke, nias lawv mus rau hauv titanium alloy electrodes los ntawm lub siab-powered ntaus ntawv, thiab ces muab tso rau hauv lub melting rauv thiab refining lawv mus rau hauv tsim nyog titanium alloy ingots tom qab. ntau lub tshuab nqus tsev melting. Lawv hu ua "Ti62A", thiab qhov kev txhim kho titanium alloy Ti62A ua tau raws li qhov xav tau ntawm lub zog thiab tawv, thiab nws cov weldability tau zoo heev. Lub koom haum ntawm Hlau tau kov yeej qhov teeb meem no nyob rau hauv ib tug poob swoop.

Txawm li cas los xij, cov teeb meem khoom siv tau raug daws, tab sis yuav ua li cas nias ob lub hemispheres thiab txuas lawv mus rau hauv tag nrho los ua qhov thib ob "txoj kev thaiv". Qhov teeb meem no tsis yog tsuas yog cuam tshuam nrog lub koom haum ntawm Hlau, tab sis kuj muaj feem xyuam rau cov txheej txheem tsim khoom ntawm lub tuam txhab.
