v2-0c41f593f019cd1ba7925cc1c0187f06_1440w(1)

Ko te tukanga maimoatanga wera o te putorino maitai te nuinga o nga waahanga e 5 e whai ake nei:

1, te tinei + te whakamahana i te pāmahana teitei (e mohiotia ana ko te tinei me te whakamahana)

Ka whakamahana te putorino maitai ki te pāmahana tinei, kia huri te hanganga o roto o te putorino maitai ki austenite, katahi ka whakamatao tere atu i te tere tiini tino nui, kia huri te hanganga o roto o te putorino maitai ki te martensite, katahi ka riri ki te pāmahana teitei, te mutunga, te hanganga putorino maitai kua puta ke ki te kakahu sopranite tempered.Ka taea e tenei tukanga kore anake te whakapai ake i te kaha me te pakeke o te putorino maitai, engari ano pararopi whakakotahi i te kaha, kirihou me te uaua o te paipa maitai.

2, te whakarite (mohiotia ano ko te whakarite)

I muri i te whakamahana i te putorino maitai ki te whakarite i te pāmahana, ka huri katoa te hanganga o roto o te putorino maitai ki te hanganga austenite, katahi ka whakamataohia te tukanga maimoatanga wera ki te hau hei reo.I muri i te whakatikatika, ka taea te whiwhi i nga hanganga whakarewa rereke, penei i te pearlite. , bainite, martensite, he ranunga ranei o ratou.Kaore e taea e tenei tukanga te whakamahine i te witi, te hanganga rite, te whakakore i te ahotea, engari ka whakapai ake i te pakeke o te paipa rino me tana mahi tapahi.

Whakariterite + te whakapouri

Ka whakamahana te ngongo maitai ki te pāmahana noa, kia tino huri te hanganga o roto o te ngongo maitai ki te hanganga austenite, ka whakamatao ki te hau, ka whakamatao. + bainite, te tempered bainite, te tempered martensite, te tempered sortensite.Ka taea e te tukanga te whakapumau i te hanganga o roto o te paipa maitai me te whakapai ake i tona kirihou me te pakari.

4, whakapouri

He tukanga maimoatanga wera i roto i te wera o te ngongo maitai ki te whakamahana i te pāmahana me te pupuri mo tetahi wa, ka whakamataohia ki tetahi pāmahana me te oumu.Whakaitihia te pakeke o te putorino maitai, te whakapai ake i tona kirihou, ki te whakahaere i nga waahanga e whai ake nei. te tapahi, te tukatuka whakaheke matao ranei; Whakapaihia te witi, te whakakore i nga hapa o te microstructure, te hanganga o roto me te hanganga o roto, te whakapai ake i te mahi o te putorino maitai, te whakarite ranei mo te tukanga e whai ake nei; Whakakorehia te ahotea o roto o te putorino maitai ki te aukati i te pakaruhanga, te pakaru ranei.

5. Te maimoatanga otinga

Ka whakamahanahia te ngongo maitai ki te pāmahana otinga, kia tino rewa nga carbide me nga mea whakarewa i roto i te austenite, katahi ka tere te whakamatao o te ngongo maitai, kia kore ai he wa ki te whakaheke, me te tukanga maimoatanga wera. o te hanganga austenite kotahi ka whiwhi.Ko te mahi o te tukanga: te hanganga o roto o te putorino maitai, te hanganga rite o te putorino maitai;Whakakorehia te pakeke i roto i te tukanga o te tukatuka ki te whakahaere i te tukatuka deformation matao muri;
