Monel 411 muaj pes tsawg leeg yog dab tsi?
Monel alloy
Monel yog ib pawg ntawm cov alloys ntawm npib tsib xee (52% mus rau 67%) thiab tooj liab, nrog me me ntawm hlau, manganese, carbon, thiab silicon. Monel alloy tseem hu ua Monel hlau. Monel alloys tsis yog tooj liab-nickel alloys vim tias lawv muaj tsawg dua 60% tooj liab. Monel tau tsim nyob rau xyoo 1905 los ntawm Robert Crooks Stanley, uas tau ua haujlwm rau International Nickel Company (Inco). Monel alloy tau muaj npe tom qab lub tuam txhab tus thawj tswj hwm Ambrose Monell thiab patented nyob rau hauv 1906. Txij li thaum lub npe tsis raug tso cai siv los ua cov cim lag luam thaum lub sij hawm, ib qho "l" raug tso tseg. Cov cim lag luam tau sau npe rau lub Tsib Hlis 1921 thiab tam sim no yog lub cim lag luam ntawm Special Metals Corporation. Monel yog ib qho khoom kim heev thiab nws txoj kev siv yog txwv rau cov ntawv thov uas nws tsis tuaj yeem hloov tau los ntawm cov khoom pheej yig dua. Monel muaj zog dua cov npib tsib xee ntshiab thiab tuaj yeem tiv thaiv corrosion los ntawm ntau yam corrosive media, nrog rau cov dej hiav txwv ceev ceev. Cov alloys no tuaj yeem ua tau yooj yim thiab tsim los ntawm kev ua haujlwm kub, ua haujlwm txias, machining thiab vuam.
Nyob rau hauv thaum ntxov xyoo, Monel alloy tau yug los ntawm kev sib koom kev tshawb fawb ntawm peb metallurgists, David H. Browne, Victor Hybinette thiab Robert C. Stanley, nyob rau hauv ib tug ntau yig txoj kev los tsim nickel nyiaj. Thaum kawg, Stanley pom tau hais tias cov nickel tooj liab sulfide pom nyob rau hauv Bessemer matte muaj qis oxidation point, tso cai rau nws los kho cov thawj ingot qhov twg lwm tus ua tsis tau tejyam. Nyob rau hauv tus txheej txheem, nws stumbled raws li ib tug heev corrosion-resistant superalloy.
Monel 400 tau siv nyob rau hauv kev lag luam thiab kev tsim kho ib puag ncig txij li xyoo 1905. Nws yog binary alloy nrog sib npaug proportions ntawm npib tsib xee thiab tooj liab, tib lub alloy uas tshwm sim nyob rau hauv tektite npib tsib xee mines hauv Sudbury (Ontario, Canada), thiab yog li ntawd suav hais tias yog ib tug Puritan alloy. Nws yog ib qho ntawm cov nickel alloys ntxov tshaj plaws, yos rov qab mus rau thawj nickel-tooj liab ore mined hauv Canada nyob rau hauv lub xyoo pua puv 19. Cov muaj pes tsawg leeg ntawm thawj ore yog roughly tib yam li cov tshuaj muaj pes tsawg leeg ntawm Monel 400 niaj hnub no. Cov hlau no yog xim nyiaj.
