Germination nke ike ọgwụgwụ mgbawa nke bolt:
Ebe mbụ ike ọgwụgwụ na-amalite na-adaba adaba na-akpọ isi iyi ike ọgwụgwụ, na ike ọgwụgwụ na-enwe mmetụta nke ukwuu maka microstructure bolt ma nwee ike ịmalite mgbawa ike ọgwụgwụ n'obere ntakịrị. N'ikwu okwu n'ozuzu, n'ime nha ọka atọ ruo ise, nsogbu ịdị mma nke bolt bụ isi ike ọgwụgwụ na ọtụtụ ike ọgwụgwụ na-amalite n'elu bolt ma ọ bụ n'okpuru ala.
Otú ọ dị, e nwere ọnụ ọgụgụ dị ukwuu nke dislocations na ụfọdụ alloying ọcha ma ọ bụ adịghị ọcha na crystal nke bolt ihe, na ọka ókè ike dị nnọọ iche, na ihe ndị a nwere ike iduga ike ọgwụgwụ mgbape mmalite. Nsonaazụ na-egosi na ike ọgwụgwụ na-adịkarị mfe ime na oke ọka, ntinye elu ma ọ bụ akụkụ nke abụọ na voids, nke niile metụtara mgbagwoju anya na mgbanwe nke ihe. Ọ bụrụ na microstructure nke bolts nwere ike imeziwanye mgbe ọgwụgwọ okpomọkụ gasịrị, ike ọgwụgwụ ya nwere ike ịbawanye ruo n'ókè ụfọdụ.
Mmetụta decarbonization na ike ọgwụgwụ:
The decarburization nke bolt elu nwere ike ibelata elu ike ike na iyi iguzogide nke bolt mgbe quenching, na nwere ike n'ụzọ dị irè ibelata ike ọgwụgwụ nke bolt. GB/T3098.1 ọkọlọtọ maka bolt arụmọrụ nke decarbonization ule. Ọnụ ọgụgụ buru ibu nke akwụkwọ na-egosi na ọgwụgwọ okpomọkụ na-ezighị ezi nwere ike ibelata ike ike ọgwụgwụ nke bolts site na decarburizing elu na ibelata mma elu. Mgbe a na-enyocha ọdịda ihe kpatara mgbaji bolt dị elu, a na-achọpụta na oyi akwa decarbonization dị na njikọ nke mkpanaka isi. Otú ọ dị, Fe3C nwere ike imeghachi omume na O2, H2O na H2 na okpomọkụ dị elu, na-ebute mbelata Fe3C n'ime ihe mkpuchi ahụ, si otú a na-amụba akụkụ ferritic nke ihe mkpuchi ahụ ma belata ike nke ihe mkpuchi.
