Ihe nkedo igwe anaghị agba nchara Duplex

Duplex igwe anaghị agba nchara(DSS) na-ezo aka na otu igwe anaghị agba nchara nwere metallographic microstructure nke ma ferrite na austenite nke ọ bụla na-aza ihe ruru 50%. N'ozuzu, ọdịnaya nke obere usoro kwesịrị ịdịkarịa ala 30%. N'ihe gbasara ọdịnaya carbon dị ala, ọdịnaya Cr bụ 18% ruo 28%, yana ọdịnaya Ni bụ 3% ruo 10%. Ụfọdụ igwe anaghị agba nchara duplex nwekwara ihe ndị na-eme ka alloying dị ka Mo, Cu, Nb, Ti, na N. DSS nwere njirimara nke austenitic na ferritic igwe anaghị agba nchara. N'iji ya tụnyere ferrite, ọ nwere plasticity dị elu na ductility, enweghị ụlọ okpomọkụ na-egbuke egbuke, ma na-eme ka nguzogide corrosion intergranular na ịrụ ọrụ ịgbado ọkụ, ebe ọ ka na-ejigide brittleness, elu thermal conductivity, na superplasticity dị ka ferrite igwe anaghị agba nchara. Tụnyereaustenitic igwe anaghị agba nchara, DSS nwere ike dị elu ma na-emeziwanye nguzogide corrosion intergranular na corrosion nrụgide chloride.
