Ebube bụ otu n'ime ihe ndị a na-ejikarị eme ihe n'ụlọ ọrụ dị iche iche na mba anyị n'afọ ndị na-adịbeghị anya, mana akụkọ mmepe ya na-ebute n'ezie n'ime obodo site na nkà na ụzụ mmepụta ígwè nke mba ọzọ. Ronsco na-ewebata akụkọ mmepe nke superalloy nkenke.

Usoro mmepe nke superalloys

Kemgbe ngwụcha afọ 1930, Briten, Jamanị, United States na mba ndị ọzọ amalitela ịmụ ihe gbasara superalloys. N'oge Agha Ụwa nke Abụọ, iji gboo mkpa nke igwe ikuku ọhụrụ, nyocha na ojiji nke superalloys batara n'oge mmepe siri ike. Na mbido 1940s, Briten buru ụzọ tinye obere aluminom na titanium na 80Ni-20Cr alloy iji mepụta usoro γ┡ maka ikesi ike, wee mepụta alloy nke mbụ dabere na nickel nwere ike dị elu dị elu. N'otu oge ahụ, United States malitere iji Vitallium cobalt alloy na-eme ka agụba iji gboo mkpa nke mmepe nke turbochargers maka piston aero-engines. Tụkwasị na nke ahụ, United States emepụtawokwa alloys dabeere na Inconel nickel iji mee ụlọ ọkụ ụgbọ elu. Mgbe e mesịrị, iji mee ka ike okpomọkụ dị elu nke alloy dịkwuo mma, ndị na-emepụta metallurgists gbakwunyere tungsten, molybdenum, cobalt na ihe ndị ọzọ na ihe ndị dị na nickel na-eme ka ọdịnaya nke aluminum na titanium dịkwuo elu, ma mepụta usoro nke alloys, dị ka British "Nimonic" na American "Mar-M" na "IN", wdg; na cobalt dabeere alloy, nickel, tungsten na ihe ndị ọzọ na-agbakwunyere ịzụlite a dịgasị iche iche nke elu-okpomọkụ alloys, dị ka X-45, HA-188, FSX-414, wdg N'ihi enweghị cobalt akụrụngwa, na Amachibidoro mmepe nke superalloys dabere na cobalt. N'afọ ndị 1940, e mepụtakwara superalloys ndị nwere ígwè. Na 1950s, ụdị dị ka A-286 na Incoloy901 pụtara. Agbanyeghị, n'ihi nkwụsi ike ha dị elu na-adịghị mma, mmepe ha ejirila nwayọ nwayọ kemgbe 1960. Ndị Soviet Union malitere ịmepụta "EИ" akara nickel nke dabeere na nickel gburugburu 1950, ma mesịa mepụta usoro "ЭП" nke superalloys ndị nwere nkwarụ na usoro "ЖС" nke nkedo superalloys. China malitere mmepụta nke superalloys nnwale na 1956, wee jiri nwayọọ nwayọọ mepụta usoro "GH" nke superalloys nwere nkwarụ na usoro "K" nke nkedo superalloys. N'afọ ndị 1970, United States nakweere usoro mmepụta ọhụrụ iji rụpụta agụba kristal na ntụ ntụ metallurgy turbine disks, wee mepụta otu agụba kristal na ihe ndị ọzọ na-ekpo ọkụ na-ekpo ọkụ iji gboo mkpa nke ịba ụba okpomọkụ na ntinye nke turbines aero-engine. .
