Black annealed tsananin magana ba talakawa annealing, amma tsari da annealing kusan.Karfe baki bututufata baki oxide!

Annealing: annealing da karfe gami yana mai zafi zuwa dace zafin jiki da kuma kula da wani lokaci, sa'an nan jinkirin sanyaya tsarin kula da zafi.Annealed karfe ne kungiyar hypoeutectoid ferrite takardar pearlite;eutectoid karfe ko eutectoid karfe ne granular pearlite.A taƙaice ƙungiyar ta rufe tana kusa da ƙungiyar ma'auni na jiha.
