High-pressure alloy pipe deformation kusimbisa iri kushandisa nzira ye deformation yekusimbisa simbi.Iyo inozivikanwawo sekuomesa kuomesa kana kushanda kuomesa.Simba rezvinyorwa pane macro (kana yakazara) kugona kuramba deformation (kana kuyerera kushushikana).Kuomarara ndiko kugona kwechinyorwa kuramba deformation yepurasitiki yakagadziriswa (ingave micro-kuoma, Vickers kuomarara, Rockwell kuomarara kana Brinell kuomarara).Ose ari maviri ane hukama hunoenderana mune dzakawanda zviitiko.Kusimba kwezvinhu, zvakanyanya kupikisa kushanduka kwepurasitiki, kunowedzera kukosha kwekuoma.Kusiyana neizvi, iyo yakakwirira kuoma kwezvinhu, zvinhu zvingave zvichikonzerwa nekuwedzera brittleness, simba rayo harina kunyatsoratidzwa musimba rakadaro index kukosha haisi yakakwirira.
Kwenguva yakareba pasi pekupisa kurapwa, uye kushandiswa kwezvinhu mumatembiricha zvakanaka pazasi recrystallization tembiricha yepamusoro-kumanikidza alloy pombi simbi pombi zvinhu (senge yakaderera kabhoni yakaderera-alloy simbi), kazhinji shandisa inotonhora (inotonhora deformation) saka kuti kuburikidza ne deformation kusimbisa kuvandudza simba.Saka, deformation inosimbisa essence iri mu recrystallization tembiricha yezvinyorwa mune inotevera inotonhora deformation, ine dhigirii ye deformation (strain) inowedzerwa, zvichikonzera kuwanda kweiyo dislocation (crystal defects), iyo yakakwirira dislocation density mukristaro. , Iyo yakakura dhigirii yekusimudzira, kureva iyo yakanyanya kuyerera kuyerera.Mushure me deformation kuyerera kushushikana kwesimbi hakufanirwe kuenzana pamberi pe deformation kuyerera kushushikana pamwe nekuwedzera deformation inosimbisa kuyerera kushushikana.Kushandisa deformation kusimbisa kuwana simba rakakwirira zvigadzirwa zvesimbi, yakajairika ndeye yakakwirira-kabhoni simbi inotonhorera-inodhonzwa waya yesimbi uye yakaderera kabhoni yakaderera-alloy duplex simbi inotonhora-inodhonzwa simbi waya.
Nekuwedzera kwedhigirii re deformation, simba rezvinhu uye kuoma kwakakwira uye kwakakwira, asi ductility uye kuoma kwayo kunowanzo kuderera uye kuderera, kuwedzera uye brittle, izvo zvinoda kuoma kutora matanho akakodzera kuvandudza mamiriro acho.Internal induced in the martensitic phase transformation phase kutonhora kwekuomesera, hunhu hwayo hwepanyama, zvakare ndeye deformation kusimbisa, asi panguva ino kwete kubva kunze deformation, asi maitiro martensitic shanduko kubva crystal Yakakwirira-density nzvimbo pachayo shear yakagadzirwa nekukanganisa.
