Tensile Strength thiab Yield Strength ntawm Monel - Kev Paub

Yuav Ua Li Cas Tensile Strength thiab Yield Strength ntawm Monel Alloys Hloov nrog Kub?

Lub zog tensile thiab yield zog ntawm Monel alloys (ib tug npib tsib xee{0}} tooj liab alloy series) ua raws likev hloov pauv tsis tu ncuanrog rau qhov kub thiab txias variations, uas yog ze ze rau lawv lub hauv paus metallurgical qauv thiab thermal stability. Txoj kev tshwj xeeb yog raws li nram no:

Nyob rau hauv qhov qis mus rau nruab nrab kub ntau yam (feem ntau los ntawm cryogenic kub txog 400 degree)

Monel alloys muaj cov thermal stability. Ob leeg lub zog tensile thiab yield zognyob twj ywm nyob rau theem siab thiab qhia me ntsis downward trendthaum kub nce. Yog vim li cas yog tias nyob rau hauv lub caij ntuj no kub, lub alloy lub siv lead ua qauv tsis dhau mus rau theem transformation, thiab lub zog poob yog feem ntau yog tshwm sim los ntawm lub weakening ntawm atomic bonding quab yuam thiab acceleration ntawm dislocation zog nrog nce kub.

Piv txwv li, Monel 400, qib siab tshaj plaws, muaj lub zog tensile ntawm kwv yees li 550-650 MPa thiab lub zog tawm los ntawm 240-310 MPa ntawm chav tsev kub. Thaum qhov kub nce mus txog 400 degree, nws lub zog tensile txo los ntawm 10% -15%, thiab lub zog tawm los ntawm 15% -20%.

Nyob rau hauv qhov kub thiab txias (siab tshaj 400℃thiab qis dua nws melting point)

Ob leeg lub zog tensile thiab yield zogpoob qis heevnrog rau qhov kub thiab txias tsis tu ncua. Thaum qhov kub siab tshaj 600 degree, lub zog poob qis heev. Qhov no yog vim hais tias lub atomic thermal motion intensifies, lub grain ciam ciam teb quab yuam tsis muaj zog, thiab cov alloy pib pom pom tseeb creep phenomenon, uas ua rau kom poob sai ntawm nws load- bearing muaj peev xwm.

Tsis tas li ntawd, qee qhov kev ua tau zoo ntawm Monel qib siab (xws li Monel K-500 tom qab kev laus kho) tau zoo dua - qhov kub thiab txias tuav vim yog nag lossis daus ntawm cov theem ntxiv (piv txwv li, Ni₃Al), thiab lawv lub zog poob qis qis dua li ntawm Monel 400 nyob rau tib qhov chaw siab.

Hauv qhov kub thiab txias (hauv qab 0 degree)

Tsis zoo li ntau cov hlau uas dhau los ua nkig ntawm qhov kub thiab txias, Monel alloys tseem muaj qhov toughness zoo heev. Meanwhile, lawv lub zog tensile thiab yield zognce me ntsisraws li qhov kub thiab txias, vim tias qhov kub tsis tshua muaj qhov cuam tshuam rau kev txav ntawm cov dislocations, ua rau cov hlau tsis muaj zog thiab muaj zog.
