Ibha Yensimbi Engagqwali Eqinisa Ubudala

Incazelo emfushane:

Ukuqina kweminyaka, okwaziwa nangokuthi ukuqina kwemvula, kuyinqubo yokwelapha ukushisa ethuthukisa amandla nobulukhuni bama-alloy athile, okuhlanganisa insimbi engagqwali.Umgomo wokwenza ukuqina ngobudala ukuheha ukuna kwezinhlayiya ezinhle ngaphakathi kwe-matrix yensimbi engagqwali, kuqinisa impahla.

    Iyini Imvula Eqinisa Insimbi Engagqwali?

    Ukusana kwemvula eyenza insimbi engagqwali ibe lukhuni, evame ukubizwa ngokuthi "PH insimbi engagqwali," iwuhlobo lwensimbi engagqwali olungena inqubo ebizwa ngokuthi ukuqina kwemvula noma ukuqina kweminyaka. Le nqubo ithuthukisa izakhiwo zemishini yezinto, ikakhulukazi amandla nokuqina kwayo. Imvula ejwayeleke kakhulu eyenza insimbi engagqwali ibe lukhuni17-4 PH(I-ASTM A705 Ibanga 630), kodwa amanye amabanga, afana no-15-5 PH kanye no-13-8 PH, nawo awela kulesi sigaba.Izinsimbi ezingenasici eziqinile ezinamanzi ngokuvamile zihlanganiswa nezinto ezifana ne-chromium, nickel, ithusi, futhi ngezinye izikhathi i-aluminium. Ukwengezwa kwalezi zakhi ze-alloying kukhuthaza ukwakheka kwe-precipitates ngesikhathi senqubo yokwelapha ukushisa.

    Imvula yensimbi engagqwali iqina kanjani?

    Ibha ye-Stainless Forgings Eqinisa Ubudala

    Ukuqinisa iminyaka yobudala insimbi engagqwali kuhilela inqubo enezinyathelo ezintathu. Ekuqaleni, i-material ibhekana nokwelashwa kwesisombululo sezinga lokushisa eliphezulu, lapho ama-athomu e-solute ancibilika, enze isisombululo sesigaba esisodwa. Lokhu kuholela ekwakhekeni kwama-nuclei amaningi amancane noma "ama-zones" ensimbi. Kamuva, ukupholisa okusheshayo kwenzeka ngaphezu komkhawulo wokuncibilika, okwenza isixazululo esiqinile esine-supersaturated esimweni sokumetastable.Esinyathelweni sokugcina, isixazululo se-supersaturated sishiselwa ezingeni lokushisa eliphakathi nendawo, okwenza kube nemvula. Impahla ibe igcinwa ikulesi simo kuze kube yilapho iba lukhuni. Ukuphumelela kokuqina kweminyaka kudinga ukwakheka kwengxubevange ukuthi kube ngaphakathi komkhawulo wokuncibilika, okuqinisekisa ukusebenza kahle kwenqubo.

    Yiziphi izinhlobo zensimbi eqinile yemvula?

    Izinsimbi eziqinisa imvula ziza ngezinhlobo ezahlukene, ngayinye yakhelwe ukuhlangabezana nezidingo ezithile zokusebenza nezinhlelo zokusebenza. Izinhlobo ezijwayelekile zifaka phakathi 17-4 PH, 15-5 PH, 13-8 PH, 17-7 PH, A-286, Custom 450, Custom 630 (17-4 PHMod), kanye ne-Carpenter Custom 455. Lezi zinsimbi zinikeza inhlanganisela yamandla aphezulu, ukumelana nokugqwala, kanye nobulukhuni, okuzenza zifanelekele izimboni ezihlukahlukene ezifana ne-aerospace, yezimoto, yezokwelapha, kanye nokucubungula amakhemikhali. Ukukhethwa kwensimbi eqinisa imvula kuncike ezintweni ezifana nemvelo yohlelo lokusebenza, ukusebenza kwempahla, kanye nokucaciswa kokukhiqiza.

     

    Ukupakisha:

    1. Ukupakisha kubaluleke kakhulu ikakhulukazi endabeni yokuthunyelwa kwamanye amazwe lapho impahla idlula eziteshini ezihlukahlukene ukuze ifike lapho kuyiwa khona, ngakho sibeka ukukhathazeka okukhethekile mayelana nokupakisha.
    2. I-Saky Steel ipakisha izimpahla zethu ngezindlela eziningi ngokusekelwe emikhiqizweni. Sipakisha imikhiqizo yethu ngezindlela eziningi, njengokuthi,
