1) kwidayagram ye-austenite isothermal yenguqu yendawo eqhelekileyo, oko kukuthi, malunga ne-500-600 ℃, amanzi kwinqanaba lefilimu yomphunga, izinga lokupholisa alikhawulezi ngokwaneleyo, lidla ngokubangela ukupholisa okungalinganiyo kunye nokungonelanga kokupholisa.isantya forgingskunye nokwakheka "kwindawo ethambileyo" .Kwinkqubo yokuguqulwa kwe-martensite, oko kukuthi, malunga ne-300-100 ℃, amanzi akwinqanaba lokubilisa, izinga lokupholisa likhawuleza kakhulu, kulula ukwenza isantya senguqu ye-martensite ngokukhawuleza kwaye ivelise uxinzelelo oluninzi lwangaphakathi, olukhokelela kwi-deformation ye-forging kunye nokuqhekeka.

2) Ubushushu bamanzi bunempembelelo enkulu kumthamo wokupholisa, ngoko ke bunovelwano kutshintsho lobushushu be-ambient. Njengoko ubushushu bamanzi bunyuka, umthamo wokupholisa wehla kakhulu, kwaye uluhlu lweqondo lobushushu leqondo eliphezulu lokupholisa lifudukela kwiqondo lobushushu eliphantsi.forgings, kodwa inefuthe elincinci kwizinga lokupholisa kuluhlu lwenguqu ye-martensite.Xa ubushushu bamanzi buphakama ukuya kuma-60 ℃, izinga lokupholisa liya kuncipha malunga ne-50%.

xa amanzi equlethe igesi eninzi (njengamanzi asanda kutshintshwa), okanye amanzi axutywe nokungcola okunganyibilikiyo, okufana neoli, isepha, udaka, njl.
Ngokweempawu zokupholisa zamanzi, amanzi ngokuqhelekileyo H anokusetyenziswa ekucimeni ukupholisa kwekhabhoniizixhobo zentsimbikunye nobukhulu icandelo elincinane kunye shape.Quenching elula, kufuneka kwakhona uqaphele: gcina ubushushu bamanzi ngaphantsi kwama-40 ℃, eyona ilungileyo phakathi 15 ukuya 30 ℃, kwaye ugcine amanzi okanye ukujikelezwa ulwelo, ukutshabalalisa umphezulu inwebu umphunga umphezulu, unako ukusebenzisa ujingi workpiece ngexesha ukucima (okanye ukwenza workpiece ishukuma phezulu kwaye ezantsi) indlela ukuguqula 0 inwebu epholileyo ℃ 0 inwebu, ukwandisa 0 inwebu epholileyo ℃. iimeko zokupholisa, kunqanda ukuvelisa indawo ethambileyo.
