4J42yi-iron-nickel fixed expansion alloy, eyenziwe kakhulu yi-iron (Fe) kunye ne-nickel (Ni), enomxholo we-nickel omalunga ne-41% ukuya kwi-42%. Ukongeza, ikwanazo nezinto ezincinci ezifana ne-silicon (Si), i-manganese (Mn), i-carbon (C), kunye ne-phosphorus (P). Olu lwakhiwo lwe-chemica luyinika ukusebenza okuhle kakhulu.

Ekuqaleni kwenkulungwane yama-20, ngokunyuka kwetekhnoloji ye-elektroniki, i-aerospace kunye nezinye iindawo, kwabekwa phambili iimfuno eziphezulu zeempawu zokwandiswa kobushushu kunye neempawu zoomatshini zezinto, kwaye abaphandi baqala ukuphonononga izixhobo ze-alloy ezineempawu ezithile. Njenge-alloy yentsimbi-nickel-cobalt, uphando kunye nophuhliso lwe-alloy yokwandiswa kwe-4J42 luza kuhlangabezana neemfuno zala macandelo ekusebenzeni kwezinto. Ngokulungisa rhoqo umxholo wezinto ezifana ne-nickel, isinyithi, kunye ne-cobalt, uluhlu oluqikelelweyo lwe-alloy ye-4J42 luye lwamiselwa kancinci kancinci, kwaye abantu baqalise ukufumana izicelo zokuqala kwezinye iindawo ezineemfuno eziphezulu zokusebenza kwezinto.

Ngokuqhubeka kwenzululwazi netekhnoloji, iimfuno zokusebenza kwe-4J42 expansion alloy nazo ziya zisanda. Abaphandi bayaqhubeka nokuphucula ukusebenza kwe-4J42 alloy ngokuphucula iinkqubo zemveliso kunye nokwenza ngcono ukwakheka kwe-alloy. Umzekelo, ukusetyenziswa kwetekhnoloji yokunyibilikisa ephucukileyo kunye netekhnoloji yokucubungula kuphucule ubunyulu kunye nokufana kwe-alloy, kwaye kunciphisa ngakumbi impembelelo yezinto ezingcolileyo ekusebenzeni kwe-alloy. Kwangaxeshanye, inkqubo yonyango lobushushu kunye nenkqubo yokudibanisa i-4J42 alloy nayo ifundwe nzulu, kwaye iiparameter zenkqubo zesayensi nezifanelekileyo ziye zaqulunqwa ukuphucula ukusebenza kwe-processing kunye nokusebenza kwe-alloy.

Kwiminyaka yakutshanje, ngophuhliso olukhawulezileyo lwezixhobo ze-elektroniki, i-aerospace, ezonyango kunye nezinye iinkalo, imfuno ye-4J42 expansion alloy iqhubekile nokukhula, kwaye intsimi yesicelo iqhubekile nokukhula. Kwintsimi yezixhobo ze-elektroniki, ngophuhliso oluqhubekayo lweesekethe ezidibeneyo, izixhobo ze-semiconductor, njl.njl., iimfuno zezinto zokupakisha ziya zisanda. I-4J42 alloy ibe yinto ebalulekileyo kwicandelo leempahla ze-elektroniki ngenxa yokusebenza kwayo okuhle kokwandisa ubushushu kunye nokusebenza kwayo kwe-welding.

Ngokuqhubeka nokuqhubela phambili kwetekhnoloji yemveliso, kuya kujongwa ngakumbi ekuphuculeni ubunyulu be-alloy kunye nokunciphisa umxholo wezinto ezingacocekanga kwixesha elizayo. Oku kuya kuphucula ngakumbi uzinzo lokusebenza kwe-alloy, kunciphise ukuguquguquka kokusebenza okubangelwa bubumdaka, kwaye kuphucule ukuthembeka kwe-alloy kwizicelo ezichanekileyo. Umzekelo, kwicandelo lokupakisha nge-elektroniki, ubunyulu obuphezulu be-4J42 alloy bunokuqinisekisa uzinzo lwexesha elide kunye nokusebenza okuphezulu kwezixhobo ze-elektroniki.
