Dabere na nha nchara, okpomoku kpo oku, oge, njirimara mgbanwe na ọnọdụ jụrụ oyi, a ga-enwerịrị ihe nrụpụta nchara agbanyụ nke martensite ma ọ bụ martensite + residual austenite, na mgbakwunye, enwere ike ịnwe obere carbide na-agbasaghị.Ma martensite na residual austenite nọ na ọnọdụ metastable na ụlọ okpomọkụ, ha na-agbanwekwa na steeti ferric mass gbakwunyere cementite kwụsiri ike.
(2) Àgwà isi ike
A na-ekpughe nhụsianya lattice nke atom carbon carbon kpatara site na isi ike, nke na-abawanye site na nnukwu saturation, ma ọ bụ ọdịnaya carbon.Ịkwụsị usoro ihe siri ike, ike dị elu, plasticity, obere ike.
(3) Àgwà nrụgide
Gụnyere nrụgide micro na nrụgide macro, nke mbụ metụtara mgbagha lattice nke carbon carbon na-akpata, karịsịa na carbon martensite dị elu iji ruo nnukwu uru, nyocha nke quenching martensite na ọnọdụ nrụgide siri ike;Nke ikpeazụ bụ n'ihi na okpomọkụ dị iche kpụrụ na cross ngalaba mgbe quenching, na workpiece elu ma ọ bụ n'etiti ọnọdụ nrụgide dị iche iche, e nwere tensile nrụgide ma ọ bụ mkpakọ nrụgide, na workpiece ịnọgide na-enwe itule.Ọ bụrụ na nrụgide dị n'ime nke akụkụ ígwè siri ike adịghị ekpochapụ n'oge, ọ ga-eme ka nrụrụ ọzọ na ọbụna mgbawa akụkụ.
N'ịchịkọta, ọ bụ ezie na quenched workpiece nwere nnukwu ike na ike dị elu, ma ikpere dị ukwuu, ihe owuwu ahụ adịghị eguzosi ike n'ihe, na e nwere nnukwu menyụọ n'ime nrụgide, n'ihi ya, ọ ga-ewe iwe iji tinye.N'ikwu okwu n'ozuzu, usoro iwe iwe bụ usoro nleba anya nke nkwụsị ígwè, ọ bụkwa usoro ikpeazụ nke usoro ikpofu ọkụ, ọ na-enye workpiece nnọọ mgbe ọchịchọ nke ọrụ.
