4J42i-iron-nickel esisigxina sokwandiswa kwe-alloy, ngokukodwa i-iron (Fe) kunye ne-nickel (Ni), enomxholo we-nickel malunga ne-41% ukuya kwi-42%. Ukongezelela, iqulethe inani elincinci lezinto zokulandelela ezifana ne-silicon (Si), i-manganese (Mn), i-carbon (C), kunye ne-phosphorus (P). Olu hlobo olulodwa lwekhemikha lunika ukusebenza okugqwesileyo.

Ekuqaleni kwenkulungwane yama-20, kunye nokunyuka kobuchwepheshe be-elektroniki, i-aerospace kunye nezinye iindawo, iimfuno eziphezulu zabekwa phambili kwiipropati zokwandisa i-thermal kunye neempawu zoomatshini bezinto, kwaye abaphandi baqala ukuhlolisisa izinto ze-alloy ezineempawu ezithile. Njenge-iron-nickel-cobalt alloy, uphando kunye nophuhliso lwe-alloy yokwandisa i-4J42 ngokuchanekileyo ukuhlangabezana neemfuno zale mimandla yokusebenza kwezinto. Ngokuqhubekayo ukulungelelanisa umxholo wezinto ezifana ne-nickel, isinyithi, kunye ne-cobalt, uluhlu olusondeleyo lokubunjwa kwe-4J42 alloy luye lwagqitywa ngokuthe ngcembe, kwaye abantu baye baqala ukufumana izicelo zokuqala kwezinye iindawo ezineemfuno eziphezulu zokusebenza kwezinto.

Ngenkqubela phambili eqhubekayo yesayensi nethekhinoloji, iimfuno zokusebenza kwe-4J42 yokwandisa ialloyi nazo ziya zinyuka ngokunyuka. Abaphandi baqhubeka nokuphucula ukusebenza kwe-4J42 alloy ngokuphucula iinkqubo zokuvelisa kunye nokuphucula ukubunjwa kwe-alloy. Ngokomzekelo, ukusetyenziswa kobuchwephesha bokunyibilikisa ubuchwephesha obuphezulu kunye nokucubungula ubuchwepheshe kuye kwaphucula ukucoceka kunye nokufana kwe-alloy, kwaye kwanciphisa ngakumbi impembelelo yezinto ezingcolileyo ekusebenzeni kwe-alloy. Ngelo xesha, inkqubo yonyango lobushushu kunye nenkqubo ye-welding ye-4J42 i-alloy nayo ifundwe ngokunzulu, kwaye iiparitha zenkqubo yenzululwazi kunye nengqiqo ziye zaqulunqwa ukuze kuphuculwe ukusebenza kunye nokusetyenziswa kwe-alloy.

Kwiminyaka yakutshanje, kunye nophuhliso olukhawulezayo lwe-electronics, i-aerospace, unyango kunye nezinye iinkalo, imfuno ye-4J42 yokwandisa i-alloy iqhubekile yanda, kwaye intsimi yesicelo iye yaqhubeka isanda. Kwintsimi ye-electronics, kunye nophuhliso oluqhubekayo lweesekethe ezidibeneyo, izixhobo ze-semiconductor, njl., Iimfuno zezinto zokupakisha ziba phezulu nangaphezulu. I-4J42 i-alloy ibe yinto ebalulekileyo kwintsimi ye-electronic packaging ngenxa yokusebenza kwayo kakuhle kwe-thermal kunye nokusebenza kwe-welding.

Ngokuqhubela phambili okuqhubekayo kobugcisa bokuvelisa, ingqwalasela engakumbi iya kuhlawulwa ekuphuculeni ukucoceka kwe-alloy kunye nokunciphisa umxholo wezinto ezingcolileyo kwixesha elizayo. Oku kuya kuphucula ngakumbi ukuzinza kokusebenza kwe-alloy, ukunciphisa ukuguquguquka kokusebenza okubangelwa ukungcola, kunye nokuphucula ukuthembeka kwe-alloy kwizicelo ezichanekileyo. Ngokomzekelo, kwintsimi yokupakishwa kwe-elektroniki, ukucoceka okuphezulu kwe-4J42 alloy kunokuqinisekisa ukuzinza kwexesha elide kunye nokusebenza okuphezulu kwamacandelo e-elektroniki.
