    Iithegi zeMveliso

    4J36 (Invar) isetyenziswa apho uzinzo oluphezulu lufuneka khona, olufana nezixhobo ezichanekileyo, iiwotshi, iigeyiji ze-seismic creep, iifreyimu zesigqubuthelo semaski zikamabonwakude, iivalvu kwiimotor, kunye newotshi ye-antimagnetic.Kuvavanyo lomhlaba, xa kufuneka kwenziwe umgangatho wokuqala (high-precision) womgangatho wokuphakama, abasebenzi beNqanaba (leveling rod) basetyenziswa.Invar, endaweni yomthi, ifiberglass, okanye ezinye iintsimbi.I-Invar struts isetyenziswe kwezinye iipiston ukukhawulela ukwanda kwe-thermal ngaphakathi kweesilinda zazo.

    I-4J36 isebenzisa i-oxyacetylene welding, i-arc ye-arc yombane, i-welding kunye nezinye iindlela ze-welding.Ekubeni i-coefficient yokwandisa kunye nokwakheka kweekhemikhali ze-alloy inxulumene kufuneka igwenywe ngenxa ye-welding ebangela utshintsho kwi-alloy composition, kungcono ukusebenzisa i-Argon arc welding filler metals ekhethwayo iqulethe i-0.5% ukuya kwi-1.5% titanium, ukwenzela ukuba ukunciphisa i-weld porosity kunye nokuqhekeka.

    Inkqubo yonyango lokushisa
    I-Anealing yokunciphisa uxinzelelo Ukufudumala ukuya ku-530 ~ 550ºC kwaye ubambe i-1 ~ 2 h.Kuyabanda
    ukuhlamba Ukuze kupheliswe ukuqina, okuveliswe kwinkqubo yokuzoba epholileyo, ebandayo.I-Annealing ifuna ukufudunyezwa kwi-830 ~ 880ºC kwi-vacuum, bamba i-30 min.
    Inkqubo yozinziso
    1. Kwimidiya ekhuselayo kwaye ishushu kwi-830 ºC, bamba i-20min.~ 1h, cima
    2. Ngenxa yoxinzelelo olwenziwa ngokucinywa, ukufudumala ukuya kwi-315ºC, bamba i-1 ~ 4h.
    Ukulumkela
    1. Ayinakuqiniswa ngonyango lobushushu
    2. Ukunyangwa komphezulu kunokuqhunyiswa kwesanti, ukupolisha okanye ukuchola.
    3. Ingxubevange ingasetyenziswa 25% hydrochloric acid pickling isisombululo kwi 70 ºC ukucima umphezulu oxidized.
