DP Dual-gawo

Kupanga:

Zomwe zimatchedwa duplex zitsulo zosapanga dzimbiri mu njira yake yolimba ya gawo la ferrite ndi austenite zimakumana ndi theka lililonse, nthawi zambiri zimakhala zochepa zomwe zili nazo ziyeneranso kufika 30%. Pankhani ya otsika C, Cr zili 18% mpaka 28%, Ni zili 3% mpaka 10%. Zitsulo zina zilinso ndi Mo, Cu, Nb, Ti, N ndi zinthu zina zophatikizira.

 

Ubwino wake.

Chitsulocho chimakhala ndi chitsulo chosapanga dzimbiri cha austenitic ndi ferritic,

1. poyerekeza ndi ferrite, plasticity, kulimba kwambiri, palibe chipinda brittleness kutentha, kukana intergranular dzimbiri ndi kuwotcherera ntchito bwino kwambiri, komanso mainta ining chitsulo Oyenerera zosapanga dzimbiri 475 ℃ brittleness ndi mkulu matenthedwe madutsidwe, ndi superplasticity ndi zina zotero.

2. Poyerekeza ndi chitsulo chosapanga dzimbiri cha austenitic, mphamvu zambiri komanso kukana kwa intergranular corrosion ndi kukana kwa chloride stress corrosion kwasintha kwambiri.

3. Chitsulo chosapanga dzimbiri chopangidwa ndi duplex chimakana kwambiri kukana kuwononga dzimbiri, komanso gawo lachitsulo chosapanga dzimbiri cha nickel.
