Wax soo saar:

Waxa loogu yeero birta birta ah ee duplex ee xalkeeda adag ee wejiga ferrite iyo austenite waxay kulmaan nus kasta, guud ahaan wax yar oo ka kooban waxyaabaha ku jira waxay sidoo kale u baahan yihiin inay gaaraan 30%. Marka la eego heerka hoose ee C, Cr oo ah 18% ilaa 28%, Ni waxa ku jira 3% ilaa 10%. Qaar ka mid ah birta ayaa sidoo kale ka kooban Mo, Cu, Nb, Ti, N iyo walxo kale oo alloying ah.

 

Faa'iidooyinka

Birtu waxay leedahay sifooyinka birta aan lahayn ee austenitic iyo ferritic,

1. marka la barbar dhigo ferrite ah, plasticity, adkaanshaha sare, ma jaban heerkulka qolka, caabbinta daxalka intergranular iyo waxqabadka alxanka ayaa si weyn loo hagaajiyay, halka sidoo kale ilaalinta birta tayo leh birta aan tayo lahayn 475 ℃ jabsi iyo conductivity kaamerada sare, la superplasticity iyo wixii la mid ah.

2. Isbarbardhigga birta birta ah ee austenitic, xoogga sare iyo iska caabinta daxalka intergranular iyo iska caabinta daxalka chloride stress ayaa si weyn u fiicnaaday.

3. Duplex birta aan daxalka lahayn ayaa iska caabin heer sare ah u leh iska caabinta daxalka, laakiin sidoo kale qayb ka mid ah birta daxalka ah ee nikkel.
