(1) Ihe eji arụ ọrụ
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 nchegbu 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.
Iwe ọkụ bụ usoro ikpo ọkụ nchara siri ike na okpomọkụ dị n'okpuru Ac1, idobe ya ruo oge ụfọdụ, wee mee ka ọ dị jụụ na ụlọ okpomọkụ. Ebumnuche ya dị mkpa bụ:
(1) n'ụzọ ezi uche na-edozi ike na ike nke ígwè, melite ike nke ígwè, nke mere na workpiece na-ezute ngwa chọrọ;
(2) kwụsiri ike Ọdịdị, nke mere na workpiece na N'ezie nke na-adịgide adịgide ngwa adịghị eme structural mgbanwe, ka stabilize style na size nke workpiece;
Enwere ike ibelata nrụgide n'ime ime nke workpiece ma ọ bụ kpochapụ iji belata nrụrụ ya ma gbochie mgbawa.
