1, engxenyeni evamile yomdwebo we-austenitic isothermal transition diagram, okungukuthi, cishe 500-600 ℃, amanzi asesiteji sefilimu ye-steam, futhi isivinini sokupholisa asisheshi ngokwanele, okuvame ukuholela "ephuzwini elithambile" elakhiwe Ukupholisa okungalingani kanye nesivinini sokupholisa esinganele sokubumba.Kuhlelo lokuguqulwa kwe-martensitic, okungukuthi, cishe 300-100 ℃, amanzi asesigabeni sokubilisa, isivinini sokupholisa siyashesha kakhulu, kulula ukwenza isivinini sokuguqulwa kwe-martensitic sishesha kakhulu futhi ukukhiqiza inani elikhulu lokucindezeleka kwangaphakathi, okuholela ekwakhiweni kwe-deformation noma ngisho nokuqhekeka.

2, izinga lokushisa lamanzi linethonya elikhulu kumthamo wokupholisa, ngakho-ke liyazwela ekushintsheni kwezinga lokushisa elizungezile.Njengoba izinga lokushisa lamanzi likhula, amandla okupholisa ancipha kakhulu, futhi izinga lokushisa lezinga eliphezulu lokupholisa lidlulela kuzinga lokushisa eliphansi. kuholela ekutheni ukubumba kungabi lukhuni, kodwa kunethonya elincane esivinini sokupholisa ebangeni lokuguqulwa kwe-martensite.Lapho izinga lokushisa lamanzi linyuselwa ku-60℃, izinga lokupholisa lizokwehla cishe ngo-50%.

3, lapho amanzi equkethe igesi eningi (njengamanzi amasha), noma amanzi axutshwe nokungcola okungancibiliki, okufana namafutha, insipho, udaka, njll., kuzonciphisa kakhulu umthamo wawo wokupholisa, ngakho ukusetshenziswa nokuphatha kufanele kuqashelwe ngokukhethekile.
Ngokusho kwezici zokupholisa zamanzi, amanzi H angasetshenziselwa ukucisha nokupholisa ama-carbon steel forgings anesayizi encane yesigaba kanye nesimo esilula.Ukucisha, kufanele futhi uqaphele: gcina izinga lokushisa lamanzi lingaphansi kuka-40 ℃, okungcono kakhulu phakathi kuka-15 kuya ku-30 ​​℃. , futhi ugcine ukujikeleza kwamanzi noma uketshezi, ukucekela phansi ulwelwesi lwe-steam olukhangayo, futhi ungasebenzisa i-swing workpiece ngesikhathi sokucisha (noma wenze i-workpiece iye phezulu naphansi) indlela yokuchitha ulwelwesi lwesitimu, ukwandisa izinga lokupholisa phakathi kuka-500-650. ℃, izimo zokupholisa, gwema ukukhiqiza iphuzu elithambile.
