Los ntawm kev sim orthogonal thiab kev sib piv, cov txheej txheem kev kho cua sov ntawm Cu14AlX aluminium bronze alloy tau ua kom zoo dua qub, thiab qhov kev txiav txim thawj zaug thiab theem nrab ntawm plaub yam cuam tshuam rau hardenability ntawm cov hlau thaum lub sij hawm kho cua sov txheej txheem tau pom: cov kua kub kub, lub sij hawm laus. , kev laus kub thiab cov kua dej kub. lub sij hawm yaj. Cov kev tshawb fawb ntxiv tau ua pov thawj tias cov alloy tuaj yeem tau txais qhov hardness siab dua ntawm 48.2HRC los ntawm 840-880 degree roj quenching solid solution thiab 570-600 degree air-cooling aging treatment. Yog vim li cas rau lub hardening yog lub uniform refinement ntawm eutectoid 2 theem thiab dispersed nag lossis daus ntawm κ theem thaum lub sij hawm kev laus.
Lub hardness kev ua tau zoo ntawm txhuas bronze alloy cov ntaub ntawv muaj feem xyuam rau ntau yam, xws li pouring kub, txias npaum li cas, purification degree, thaum tshav kub kub txheej txheem, thiab lwm yam. los txhim kho hardness ntawm cov ntaub ntawv alloy. Lub zog ntawm aluminium bronze feem ntau yog ua los ntawm cov khoom siv tshuaj, nag lossis daus, dispersion thiab lwm txoj kev. Cov yam ntxwv xws li kev daws teeb meem thiab kev laus kub thiab lub sijhawm ntawm kev kho cua sov yog qhov tseem ceeb cuam tshuam rau theem kev hloov pauv thiab theem faib ntawm cov hlau. Qhov zoo sib xws tus nqi ntawm tag nrho cov txheej txheem tsis tsuas yog nkim ntau lub zog thiab cov khoom siv, tab sis kuj nrhiav tsis tau cov kev ntsuam xyuas zoo thiab kev ntseeg siab. Yog li ntawd, qhov kev xeem orthogonal yog siv los npaj thiab rationally teem tsawg lub sij hawm xeem thiab lub voj voog luv luv ntawm lub rooj orthogonal, sai sai nrhiav cov ntsiab lus tseem ceeb uas cuam tshuam rau cov txiaj ntsig ntsuas, thiab tom qab ntawd pom cov txheej txheem zoo.
