Vim li cas Kev Kho Cov Tshuaj Kho Kom Zoo Rau Nickel -raws li Alloys?

Yuav luag tag nrho cov nickel alloys xav tau kev kho mob vim hais tias kev kho cov tshuaj ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm cov alloys. Kab lus no yuav qhia txog cov hauv paus ntsiab lus thiab kev ua haujlwm ntawm lub cev daws teeb meem los ntawm ntau yam.

 

Los ntawm txoj kev xav macroscopic, lub cev daws teeb meem yog cov txheej txheem ntawm kev sib cais lwm yam hlau (xws li hlau, chromium, molybdenum, thiab lwm yam) rau hauv cov hlau nickel. Nws zoo ib yam li cov txheej txheem ntawm dissolving ntsev hauv dej. Txawm li cas los xij, ib yam li nws lub npe qhia, lub cev daws teeb meem yog kev sib cais ntawm cov khoom siv. Vim lub zog qeeb qeeb ntawm cov khoom atoms, cov kev daws teeb meem dav dav yuav tsum tau ua kom sov cov hlau mus rau qhov kub thiab txias kom cov atoms txav tau yooj yim dua, yog li ua tiav lub hom phiaj tawg.

 

Los ntawm qhov kev xav ntawm microscopic, lub cev kev daws teeb meem yog cov txheej txheem ntawm lwm cov hlau uas nkag mus rau cov nickel siv lead ua los ua lub ntsej muag tshiab -centered cubic qauv. Lub ntsej muag -centered cubic crystal tom qab tov yog hu ua austenite.

 

Txoj kev daws teeb meem yog qhia hauv daim duab hauv qab no:

Cov laj thawj tseem ceeb ntawm kev ua cov tshuaj daws teeb meem ntawm nickel-raws li alloys suav nrog cov hauv qab no:

1. Dissolving theem ob kom ua tiav homogenization

2. Txhim kho siab -kub kev ua haujlwm

3. Npaj rau kev laus tom ntej

4. Tshem tawm kev ntxhov siab thiab txhim kho plasticity

5. Tswj cov nplej loj
