Ngwongwo, Uru na Ngwa nke Iron Ductile

Iron Ductile, nke a makwaara dị ka spheroidal ma ọ bụ nodular iron, bụ otu ígwè alloys nwere microstructure pụrụ iche nke na-enye ha ike dị elu, mgbanwe, ịdịte aka, na elasticity. Ọ nwere ihe karịrị pasenti 3 carbon ma nwee ike ịgbagọ, gbagọọ, ma ọ bụ nwee nkwarụ n'emebighị, n'ihi nhazi flake graphite ya. Ígwè úkwù yiri ígwè n'ụdị arụ ọrụ ya ma sie ike karịa ígwè nkedo ọkọlọtọ.

Kedu ihe na-eme Iron Ductile pụrụ iche?

Emepụtara ígwè ductile n'afọ 1943 dị ka nkwalite ọgbara ọhụrụ karịa ígwè nkedo ọdịnala. N'adịghị ka nkedo ígwè, ebe graphite pụtara dị ka flakes, ductile iron nwere graphite n'ụdị spheroids, n'ihi ya okwu bụ "spheroidal graphite." Ihe owuwu a na-eme ka ígwè ductile nwee ike iguzogide nkpudo na ujo na-enweghị mgbawa, na-enye nkwụsi ike dị ukwuu karịa ígwè nkedo ọdịnala, nke na-enwekarị mgbaji na mgbaji.

A na-eji ígwè ezì eme ihe bụ́ isi nke úkwù, ígwè dị ọcha nke nwere ihe karịrị 90% iron.

Njirimara nke Iron Ductile

A na-emepụta ọkwa dị iche iche nke ígwè ductile site n'ịgbanwe usoro matrix gburugburu graphite n'oge nkedo ma ọ bụ site na ọgwụgwọ okpomọkụ ọzọ. A na-emepụta obere mgbanwe ndị a dị iche iche iji nweta microstructures kpọmkwem, nke n'aka nke ya na-ekpebi njirimara nke ọkwa ọ bụla nke ígwè ductile.

Enwere ike iche ígwè ductile dị ka ígwè nwere spheroids graphite agbakwunyere. Ihe e ji mara matriks ọla gbara gburugburu graphite spheroids na-emetụta nke ọma njirimara nke ígwè ductile, ebe graphite n'onwe ya na-enye aka na ngbanwe na mgbanwe ya.

Enwere ụdị matrices dị iche iche na iron ductile, nke a bụ nke a na-ahụkarị:

1. 1. Ferrite- Akara igwe dị ọcha nke na-agbanwe agbanwe ma na-agbanwe agbanwe, mana nwere ike dị ala. Ferrite nwere nguzogide iyi na-adịghị mma, mana nguzogide mmetụta ya dị elu yana ịdị mfe nke imepụta ihe na-eme ka ọ bụrụ akụrụngwa bara uru na akara ule ductile iron.
2. 2. Pearlite- Ngwakọta ferrite na ígwè carbide (Fe3C). Ọ dịtụ ike na ductility na-agafeghị oke, na-enye ike dị elu, nkwụsi ike dị mma na nguzogide mmetụta na-agafeghị oke. Pearlite na-enyekwa ezigbo igwe.
3. 3. Pearlite/Ferrite- Ngwakọta agwakọta na ma pearlite na ferrite, nke bụ matriks kachasị na akara azụmaahịa nke ígwè ductile. Ọ na-ejikọta njirimara nke abụọ ahụ, na-enye usoro ziri ezi maka ike, ductility, na machinability.
