Umahluko phakathi kwentsimbi ye austenitic kunye ne ferritic

Umahluko ophambili phakathiintsimbi ye-austenitickunye ne-ferritic steel stainless ilele kwizakhiwo kunye neepropathi zazo.

I-Austenitic stainless steel yintlangano ehlala izinzile kuphela kumaqondo obushushu angaphezu kwama-727 ° C.Ibonisa iplastiki elungileyo kwaye sisakhiwo esikhethwayo kwiintsimbi ezininzi eziphantsi koxinzelelo lobushushu obuphezulu.Ukongeza, intsimbi ye-austenitic ayinamagnetic.

I-Ferrite sisisombululo esiqinileyo sekhabhoni echithwe kwi-α-iron, ehlala ifanekiselwa njenge-F. Inyenziwe ngentsimbi eshayinayo, "i-ferrite" ibhekisela kwisisombululo esiqinileyo sekhabhoni kwi-α-iron, ebonakaliswe kukunyibilika kwayo okulinganiselweyo kwekhabhoni.Kwiqondo lokushisa lokushisa, linokuchithwa kuphela ukuya kwi-0.0008% yekhabhoni, ifikelele kwi-carbon solubility ephezulu ye-0.02% kwi-727 ° C, ngelixa igcina i-cubic lattice egxininiswe emzimbeni.Idla ngokumelwa luphawu F.

Umahluko phakathi kwentsimbi ye austenitic kunye ne ferritic

Kwelinye icala, ferriticyenziwe ngentsimbi eshayinayoibhekisa kwintsimbi engatyiwayo ubukhulu becala eyakhiwe sisakhiwo se-ferritic ngexesha lokusetyenziswa.Iqulethe i-chromium kuluhlu lwe-11% ukuya kwi-30%, ebonisa i-cubic crystal structure egxile kumzimba.Umxholo wentsimbi yensimbi engenasici ayihambelani nokuba ihlelwa njengensimbi engenasici ye-ferritic.

Ngenxa yomxholo wekhabhoni ephantsi, i-ferritic stainless steel ibonakalisa iimpawu ezifana nentsimbi ecocekileyo, kuquka iplastiki egqwesileyo kunye nokuqina kunye nesantya sobude (δ) se-45% ukuya kwi-50%.Nangona kunjalo, amandla ayo kunye nokuqina kwayo kuphantsi, inamandla okuqina (σb) amalunga nama-250 MPa kunye nobunzima beBrinell (HBS) wama-80.
