Which of the following microconstituents/phases are most commonly found in stainless steels?

Group of answer choices

Ferrite, Pearlite, and T-martensite

Pearlite, Austenite, and T-martensite

Pearlite, Martensite, and Austenite

Ferrite, Pearlite, Martensite, Austenite, T-martensite

Ferrite, Martensite, and Austenite

Answer 1

1.Option C Pearlitic malleable

When white cast iron is reheated to ~700 ˚C with fast cooling Pearlitic malleable occurs.

If it is done with slow cooling Ferritic malleable occurs

2.Option E Both pearlite and ferrite

3.Option C Sintering

Sintering is used to produce a small phase ceramic materials such as TiO2

4.Option E Ferrite, Martensite, and Austenite

Pearilite is very rarely found in stainless steel.Most common microconstituents of stainless steel are Ferrite, Martensite, and Austenite
