Machineability
Zoo machinability. Nws tuaj yeem ua tiav los ntawm kev tig, milling, drilling thiab lwm yam txheej txheem machining, thiab tom qab ntawd hardened los ntawm kev laus. Tshuab Cheebtsam nyob rau hauv cov mos mos Condition A (kev daws teeb meem annealed), ces ua qhov qis -kub los nag lossis daus hardening tshav kub kho kom txo tau distortion thiab ntev lub cuab tam.
"Vim li cas peb fim machining distortion thiab dimensional variance thaum machining 17-4PH daim hlau tom qab kev kho cua sov?"
Qhov no yog vim hais tias lub microstructural transformation tshwm sim thaum lub sij hawm nag lossis daus hardening txheej txheem ua rau me ntsis volumetric shrinkage. Qhov kev ua haujlwm zoo tshaj plaws suav nrog kev ua haujlwm ntxhib (tso tawm ntawm kev siv tshuab), ua raws li kev kho cua sov (kev laus), thiab thaum kawg precision tiav; qhov no ua tau zoo tiv thaiv cov khib nyiab siab uas yuav ua rau muaj kev cuam tshuam los ntawm tshav kub-kev kho mob- ntxias deformation.
