Kodi mungapewe bwanji kupanga kupsinjika kothetsa nthawi yoziziritsa wamba?

Ndiye mungapewe bwanji kupanga zothetsa nkhawa panthawi yamuyezo mwatsatanetsatane nkhungu mazikokuziziritsa?
A tempering ayenera kugwiritsidwa ntchito kuthetsa nkhawa, ndipo pambuyo kuzimitsa zitsanzo muyezo, wiritsani 30 ~ 60min pamaso kuzirala mankhwala, kuchotsa 15% mpaka 25% quenching nkhawa, kukhazikika otsalira aus, ndiye ikuchitika - 60 ° C ochiritsira kuzirala mankhwala kapena ozizira kwambiri. mankhwala -120 ° C.

Kutsika kwa kutentha, m'pamenenso kusintha kotsalira kwa austenite ndi chiwerengero cha martensite, koma sikutheka kusintha. Zotsatira zoyeserera zikuwonetsa kuti otsalira austenite amawerengera pafupifupi 2% mpaka 5%, ndipo pang'ono otsalira austenite amatha kupangitsa kupsinjika pang'onopang'ono komanso kusungika. Popeza chotsalira cha austenite ndi chofewa komanso cholimba, chimatha kuyamwa pang'ono mphamvu yakukulirakulira kwamphamvu, ndikuchotsa kupsinjika kwa gawo. Pambuyo pa mankhwala ozizira, chitsanzo chokhazikika chimatengedwa m'madzi otentha kuti chitenthe kutentha, ndipo 40% -60% kupsinjika kwa mankhwala ozizira kumatha kuthetsedwa. Kutentha kukakwera mpaka kutentha, kuyenera kuchepetsedwa nthawi kuti athetsere kupsinjika kwamankhwala ozizira, kupewa kupanga ming'alu yamankhwala ozizira, kupeza minofu yokhazikika ndi magwiridwe antchito, kuonetsetsa kutimuyezo mwatsatanetsatane nkhungu maziko sizowonongeka panthawi yosungira ndikugwiritsa ntchito.
