Deformation kusimbiswa kwepaipi yakakwira alloy

Highalloy pipedeformation kusimbisa ndiko kushandiswa kwesimbi yekusimbisa nzira.Iyo inozivikanwawo sekuomesa kana kuomesa.Simba rezvinyorwa pane macro (kana iyo yese) kugona kuramba deformation (kana kuyerera kushushikana).Kuomarara ndiko kugona kwechinyorwa kuramba deformation yepurasitiki yenzvimbo (kungave kuoma, kuomarara kweVickers, Rockwell kuomarara kana Brinell).Ose ari maviri ane hukama hunoenderana mune dzakawanda zviitiko.Kusimba kwezvinhu, iyo yakakura kupikisa kwepurasitiki deformation, iyo yakakwirira 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 ye alloy chubhu yakakwirira-kumanikidza simbi pombi zvinhu, kazhinji kushandisa inotonhora (inotonhora deformation) zvinoreva kuti kuita kuburikidza deformation kusimbisa kuvandudza simba.Nekudaro, deformation inosimbisa essence recrystallization tembiricha yechinhu chinotevera kutonhora deformation, ine dhigirii ye deformation (kuomerwa) inowedzerwa, zvichikonzera kuwanda kweiyo dislocation (crystal defects), iyo yakakwirira dislocation density mukristaro, iyo yakakura dhigirii rekusimudzira, iyo yakakwirira yekuyerera kushushikana.Mushure me deformation kuyerera kushushikana kwesimbi machubhu haifanire kuenzana pamberi pekuyerera kushushikana deformation inosimbisa deformation pamwe nekuwedzera kuyerera kushushikana.Kushandisa deformation kusimbisa kuwana simba rakakwirira zvigadzirwa zvesimbi, yakajairika yakakwirira-kabhoni simbi inotonhorera-inodhonzwa simbi waya uye yakaderera-kabhoni yakaderera-alloy duplex simbi inotonhora-inodhonzwa simbi waya.

Nechiyero che deformation chinowedzera, kusimba kwezvinhu uye kuoma kwakakwira uye kwakakwira, asi ductility uye kuoma kwayo kunowanzo kuderera uye kuderera, kuwedzera uye brittle, izvo zvinoda kutora matanho akaomarara kuvandudza mamiriro acho.Yemukati inokonzereswa mumartensitic phase shanduko panguva yekutonhora yekuomesa, hunhu hwayo hwemuviri, zvakare ndeye deformation kusimbisa, asi panguva ino kwete kubva kunze deformation, asi kubva martensitic shanduko muitiro wekristaro yakakwira-density bit pachayo shear yakagadzirwa nekukanganisa. .
