Khoom cim npe

4J36 (Invar) yog siv qhov kev ruaj ntseg siab, xws li cov cuab yeej precision, moos, seismic creep gauges, TV duab ntxoov ntxoo-mask thav duab, li qub hauv motors, thiab antimagnetic watches. Hauv kev soj ntsuam av, thaum thawj qhov kev txiav txim siab (high-precision) nce qib yuav tsum tau ua, cov neeg ua haujlwm Theem (leveling pas nrig) siv los ntawmInvar, tsis yog ntoo, fiberglass, lossis lwm yam hlau. Invar struts tau siv nyob rau hauv qee lub pistons los txwv lawv cov thermal expansion hauv lawv lub tog raj kheej.

4J36 siv oxyacetylene vuam, hluav taws xob arc vuam, vuam thiab lwm yam vuam txoj kev. Txij li cov coefficient ntawm kev nthuav dav thiab tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau yuav tsum raug zam vim qhov vuam ua rau muaj kev hloov pauv ntawm cov hlau alloy, nws yog qhov zoo dua los siv Argon arc vuam vuam welding muab tub lim hlau nyiam dua muaj 0.5% mus rau 1.5% titanium, thiaj li. txo weld porosity thiab tawg.

Cov txheej txheem kev kho cua sov
Annealing rau kev ntxhov siab	Kub rau 530 ~ 550ºC thiab tuav 1 ~ 2 teev. Txias cia
annealing	Nyob rau hauv thiaj li yuav tshem tawm hardening, uas yuav coj tawm nyob rau hauv txias-dov, txias txheej txheem. Annealing xav tau cua sov rau 830 ~ 880ºC hauv lub tshuab nqus tsev, tuav 30 feeb.
Cov txheej txheem stabilization	Hauv kev tiv thaiv xov xwm thiab cua sov rau 830 ºC, tuav 20 feeb. ~ 1h, taj Vim qhov kev ntxhov siab tsim los ntawm quenching, rhuab mus rau 315ºC, tuav 1 ~ 4h.
Cov kev ceev faj	Tsis tuaj yeem hardened los ntawm kev kho cua sov Kev kho deg tuaj yeem yog sandblasting, polishing lossis pickling. Alloy tuaj yeem siv 25% hydrochloric acid pickling tov ntawm 70 ºC kom tshem tawm oxidized nto
