Black annealed yakasimba ichitaura kwete yakajairwa annealing, asi maitiro uye annealing anenge.Simbi nhema pombiganda rakasviba oxide!

Annealing: annealing iyo simbi alloy inopisa kusvika kune yakakodzera tembiricha uye kuchengetedza imwe nguva, uyezve kunonoka kutonhora kupisa maitiro ekurapa.Annealed simbi isangano hypoeutectoid ferrite sheet pearlite;eutectoid simbi kana eutectoid simbi iri granular pearlite.Muchidimbu annealing sangano iri pedyo ne equilibrium state organisation.

Chinangwa chekudzivirira

①kuderedza kuoma kwesimbi, yakagadziridzwa ductility, kuitira kufambisa kucheka uye kutonhora deformation processing.

②kunatsiridza zviyo, kubvisa kukanda, kuumba, welding kukanganisa kunokonzerwa nesangano, kurongeka uye kuumbwa kwesimbi ine homogeneous, simbi yekuvandudza mashandiro kana yekuzotevera kupisa kurapwa kwekugadzira tishu.

③kubvisa kushushikana kwemukati musimbi kudzivirira deformation uye kuputika.
