Kugadzira 1000MPaCP yakajairwa inotonhora yakakungurutswa simbi inodzoreredzwa inodziyiswa kune annealing tembiricha yenzvimbo yakakosha, yozotonhodzwa nekuchengetwa panosvika mazana mana isothermal deg.] C, pamusoro peiyo martensite yekutanga tembiricha (Ms).

1. Vhoriyamu muzana yeferrite uye kabhoni yemukati nharaunda iyo yakakosha annealing tembiricha uye kutonga nguva.Munguva yekutonhodza uye kuvharisa, chikamu chenharaunda yakaoma austenite kupinda bainite.

2. Austenite mu bainite vhoriyamu, ye isothermal bainite shanduko tembiricha uye kuona nguva uye C zvirimo mu austenite uye bainite yekutanga tembiricha (yeBs) yeTI basa.Inoteverwa nekutonhora kusvika kukamuri tembiricha mukuita, kuumbwa kwemartensite, asi vamwe vanogona kuchengetedza shanduko yeaustenitic.

3. Usati wanyura Surface 0.3% Cr uye 0.5% Cr masimbi ane XPS.Zvakare takadzidza mhedzisiro yemhando mbiri nembiri dzeannealing choto chinopisa tembiricha yedova.

4. 304 isina musono simbi alloying zvinhu Si, Mn uye Cr pakadzika dova nzvimbo segregation kusvika pamusoro kuumba oxide.Muzvese tembiricha yeannealing, yakafanana pamusoro pekuumbwa.Musiyano wetembiricha wakanyanya kudiki, zvekuti kupatsanurwa kwezvinhu zvealloying muhuwandu hwekusina kukosha kwakakosha.

5. Cr yemukati ndeye 0.3%, Cr mari ishoma pamusoro, asi hapana kukanganisa kune zvimwe zvinhu.MuCr2p3 peak simba base, Cr iri muchimiro cheCr2O3 inoonekwa pamusoro.
