Omaka bomkhiqizo

4J36 (I-Invar) isetshenziswa lapho kudingeka khona ukuzinza kwe-dimensional ephezulu, njengamathuluzi anembayo, amawashi, ama-gauge e-seismic creep, amafreyimu emaski kamabonakude, ama-valve kumamotho, namawashi e-antimagnetic. Ekuhloleni umhlaba, lapho kufanele kwenziwe izinga lokuqala (lokunemba okuphezulu) kokuphakama, izisebenzi Zezinga (induku yokulinganisa) ezisetshenziswayo zenziwe nge-Invar, esikhundleni sokhuni, i-fiberglass, noma ezinye izinsimbi. Ama-Invar struts asetshenziswa kwamanye ama-piston ukukhawulela ukwanda kwawo okushisayo ngaphakathi kwamasilinda awo.

I-4J36 sebenzisa i-oxyacetylene welding, i-arc welding kagesi, i-welding nezinye izindlela zokushisela. Njengoba i-coefficient yokunwetshwa kanye nokwakheka kwamakhemikhali engxubevange kuhlobene kufanele kugwenywe ngenxa yokuthi i-welding idala ushintsho ekubunjweni kwengxubevange, kungcono ukusebenzisa izinsimbi zokugcwalisa welding we-Argon arc okungcono iqukethe i-0.5% kuya ku-1.5% titanium, ukuze ukunciphisa i-weld porosity kanye nokuqhekeka.

Inqubo yokwelapha ukushisa
I-Annealing yokunciphisa ukucindezeleka	Kushisiswe ku-530~550ºC futhi kubambe 1~2 h. Kuphole phansi
ukwehlisa	Ukuze kuqedwe ukuqina, okumele kukhishwe ngenqubo yokudweba ebandayo, ebandayo. I-Annealing idinga ukushisisa kufika ku-830~880ºC ku-vacuum, bamba imizuzu engama-30.
Inqubo yokuzinzisa	Kumidiya evikelayo futhi kushisiswe ku-830 ºC, bamba i-20min. ~ 1h, cisha Ngenxa yokucindezeleka okukhiqizwa ukucisha, kushisiswe ku-315ºC, bamba 1~4h.
Izinyathelo zokuzivikela	Ayikwazi ukwenziwa lukhuni ukwelashwa okushisa Ukwelashwa okungaphezulu kungaba ukuqhunyiswa kwesihlabathi, ukupholisha noma ukucotshwa. Ingxubevange ingasetshenziswa 25% isixazululo hydrochloric acid pickling at 70 ºC ukusula ebusweni oxidized
