Hana ʻana:

ʻO ke kila kila duplex i kapa ʻia he hui paʻa o ka ferrite a me ka austenite i loko o ka hapalua o kēlā me kēia, a ʻo ka nui o ka ʻike maʻamau he 30%, a ʻo ka nui o ka ʻike he 18% a 28%, a ʻo ka nui o ka Ni he 3% a 10%. Aia pū kekahi kila i loko o Mo, Cu, Nb, Ti, N a me nā mea hoʻohuihui ʻē aʻe.

 

Nā Pōmaikaʻi.

Loaʻa i ke kila nā ʻano o ke kila kila austenitic a me ka ferritic,

1. Ke hoʻohālikelike ʻia me ka ferrite, ʻoi aku ka maikaʻi o ka plasticity, ka paʻakikī kiʻekiʻe, ʻaʻohe brittleness i ka mahana o ka lumi, kū'ē i ka intergranular corrosion a me ka hana kuʻihao, a mālama pū i ka hao. He 475 ℃ brittleness ka kila kila maikaʻi a me ke conductivity thermal kiʻekiʻe, me ka superplasticity a pēlā aku.

2. Ke hoʻohālikelike ʻia me ke kila kila austenitic, ua hoʻomaikaʻi nui ʻia ka ikaika kiʻekiʻe a me ke kūʻē ʻana i ka corrosion intergranular a me ke kūʻē ʻana i ka corrosion stress chloride.

3. He kūpaʻa maikaʻi loa ke kila kila Duplex i ke kūpaʻa ʻana i ka pala ʻana o ka lua, akā he ʻāpana kila kila nickel hoʻi.
