Imveliso 1000MPaCP umjikelo wentsimbi epholileyo eqengqelekayo iphinda ifudunyezwe kwiqondo lobushushu lobushushu bommandla obalulekileyo, emva koko ipholiswe kwaye igcinwe malunga ne-400 isothermal deg.] C, ngaphezu kweqondo lobushushu lokuqala le-martensite (Ms).

1. Ipesenteji yevolumu yendawo ye-ferrite kunye nekhabhoni ebaluleke kakhulu kwiqondo lokushisa kunye nokulawula ixesha.Ngexesha lokupholisa kunye nokugquma, inxalenye yommandla obalulekileyo i-austenite ibe yi-bainite.

2. I-Austenite ibe yivolumu ye-bainite, ye-isothermal bainite yokutshintsha ubushushu kunye nokumisela ixesha kunye nomxholo we-C kwiqondo lokushisa lokuqala le-austenite kunye ne-bainite (ye-Bs) kumsebenzi we-TI.Kulandelwa ukupholisa kwiqondo lokushisa kwigumbi kwinkqubo, ukubunjwa kwe-martensite, kodwa abanye banokugcina inguqu ye-austenitic.

3. Phambi kwedip Surface 0.3% Cr kunye ne-0.5% Cr iintsimbi ezineXPS.Kananjalo siye safunda ngeziphumo zeentlobo ezimbini nezimbini zeziko lokutshisa iqondo lombethe.

4. I-304 i-alloying yentsimbi engenamthungo engenamthungo i-Si, Mn kunye ne-Cr kwindawo ephantsi yokwahlulwa kombethe kumphezulu ukwenza i-oxide.Kuwo omabini amaqondo obushushu, umphezulu ofanayo ubume.Umahluko weqondo lobushushu umncinci kakhulu, ukuze ukwahlulwa kwezinto ezixubeneyo kwisixa esingenampembelelo ibalulekileyo.

5. Umxholo we-Cr ngu-0.3%, isixa se-Cr sincinci kumphezulu, kodwa akukho mpembelelo kwezinye izinto.Kwisiseko samandla encopho ye-Cr2p3, i-Cr ngokohlobo lwe-Cr2O3 ibonakala kumphezulu.
