Nga whakaipoipoi muri i te tinei, te martensite me te austenite e mau tonu ana kare e mau, he ahua ohorere to ratou whakarereketanga o te whakahaere ki te pumau, penei i te waro supersaturated i roto i te martensite ki te whakaheke i te toenga o te austenite hei whakatairanga i te nekehanga, penei mo te whakamarumaru he whakahaere kore-taurite. ki te whakataurite i nga tukanga a te whakahaere, ka whakawhirinaki tenei tukanga ki te hekenga ngota me te tohatoha o tenei whakamanatanga me to oti te pāmahana ahi. teitei ake, te tere tiritiri tere; Engari, me te pikinga o te pāmahana whakamahana, ko te hanganga tinei o nga whao ka pa ki etahi huringa. E ai ki te ahuatanga o te whakarereketanga microstructure, ka wehewehea te whakamaarama ki nga waahanga e wha: te pirau martensite, te toenga o te austenite decomposition, te tipu whakaemi carbide me te ferrite recrystallization.
Te wahanga tuatahi (200)
(1) te patupatute whakamahana martensite ka pirau i raro i te 80 te whakamahana i te pāmahana, te tinei i te rino kaore he huringa whakahaere a Ming S, te puta o te waro i roto i te martensite he waahanga noa iho, kaore he tiimata ki te pakaru i roto i te 80-200 te whakamahana, ka tiimata te martensite ki te pirau, ka whakahekehia nga carbide tino mohio, whakaitihia te te hautanga papatipu o te martensite i roto i nga waro whakahiato i tenei wahanga, na te iti o te whakamahana, te martensitic. ko te rerenga he wahanga o nga ngota waro haunga, no reira ko te waro tonu i roto i te - Fe wairewa totoka supersaturatedKa toha rite te rerenga o te waro tino pai ki roto i te kopu o te martensite. Ko te hanganga whakauru o te Martensite iti me te carbide tino pai e kiia ana ko te Martensite tempered.

(2)te patupatute whakamahana i te wahanga tuarua (200-300), te toenga austenite decomposition ka piki te pāmahana ki te 200-300, ka haere tonu te pirau o te martensite, engari ko te huringa nui ko te toenga austenite decomposition o te toenga austenite decomposition na roto i te roha o nga ngota waro. ki te hanga i tetahi waahanga waahanga, katahi ka pakaruhia ki te wahanga alpha me te ranunga o te whakahaere carbide, ara ko te hanga o te pakeke rino bainite ehara i te mea kua tino heke i tenei wahanga
(3)Ko te wahanga tuatoru (250-400) te hurihanga carbide o te whakamaarama i roto i tenei awhe pāmahana. Na te nui o te pāmahana, ka kaha ake te kaha o te ngota ngota waro, te kaha ki te whakaora i nga ngota rino, te martensite te whakaheke i te whakawhiti o te carbide rerenga me te toenga o te austenite decomposition ka huri hei cimentite me te wehe me te hurihanga o nga carbide, te heke. o te martensite i roto i te hautanga waro papatipu, ka ngaro te kotiti martensite lattice, te panoni martensitic mo te ferrite, whiwhi Ko te tohatoha matrix ferritic i roto i te cementite iti, ko te lamellar cementite ranei o te whakahaere, ko te whakahaere e kiia nei ko te tempering i tino whakakorehia tenei waahanga austenite tinei ahotea, te pakeke, te uaua kirihou i pai ake.

(4)Ko te wha o nga wahanga o te whakamaaramatanga (& GT; 400) i tipu ake te carbide i kohia me te whakamaaramatanga o te ferrite na te mea he tiketike rawa te pāmahana, he kaha te kaha o nga ngota waro me te rino ki te tipu, ko te wahanga tuatoru o te hanganga o nga tawerewere cimentite ka huri haere tonu ka tipu haere. Neke atu i te 500-600, ka tere te whakamaaramatanga o te alpha, ka ngaro te ahua o te ferrite o te taketake. pereti takai pepa ranei, me te hanga polygon tohanga witi i runga i te whakahaere rite te ferritic matrix granular carbide, te rōpū i huaina tempering sorbite tempered sorbite ki te pai āhuatanga mīhini whānui o te wāhanga me te distortion lattice whakakore ahotea roto.
