Cov txheej txheem kev kho cua sov yooj yim yog lwm qhov tseem ceeb ntawm maraging steel.
Tom qab ua haujlwm kub, Maraging300 yuav tsum tau txais kev kho mob ua ntej ua haujlwm txias thiab kev laus zog. Lub hom phiaj yog kom yaj cov seem seem tom qab ua haujlwm kub; Dissolve lub matrix nrog cov ntsiab lus muaj zog txaus; Cov qauv martensitic nrog siab dislocation ceev tau txais.
Cov tshuaj kub yog feem ntau 820 ~ 840 degree, lub sij hawm daws yog 1h ib 25ram thickness, thiab tus nqi cua txias muaj me ntsis cuam tshuam rau cov qauv thiab cov khoom tom qab tov. Lub zog siab ntawm maraging steel yog tau los ntawm kev laus kev kho mob. Kev laus kub yog feem ntau 480 degree, thiab 510 degree tuaj yeem siv rau cov hlau nrog qib siab zog. Lub sijhawm laus yog 3 ~ 6h, thiab cua txias tom qab kev laus.
Tom qab kev laus, ib tug loj tus naj npawb ntawm dispersed thiab ultra-microscopic intermetallic compound hais yog precipitated nyob rau hauv lub martensite matrix, uas ua rau lub zog ntawm cov khoom ob npaug thiab lub toughness poob yog me me.
