0 0 votes In $Fe-Fe_{3}C$ phase diagram, the eutectoid composition is $0.8$ weight $\%$ of carbon at $725^{\circ}C$. The maximum solubility of carbon in $\alpha$-ferrite phase is $0.025$ weight $\%$ of carbon. A steel sample, having no other alloying element except $0.5$ weight $\%$ of carbon, is slowly cooled from $1000^{\circ}C$ to room temperature. The fraction of pro-eutectoid $\alpha$-ferrite in the above steel sample at room temperature is $0.387$ $0.864$ $0.475$ $0.775$ Engineering Materials gateme-2022-set1 materials-manufacturing-and-industrial-engineering engineering-materials numerical-answers + – ♦Arjun 403 views answer comment Share Follow Add Sync Questions 0 reply Please log in or register to add a comment.
