Determine the validity of each of the following statements conceding the Fe-Fe_3

Question

Determine the validity of each of the following statements conceding the Fe-Fe_3C steel system. Toughness in steels is derived from having a continuous cementite matrix. Carbon is generally more soluble in austenite (y-Fe) than finite (a-Fe) B. False Austenite (y-Fe) is more ductile than finite (a-Fe) Strength in steels increases with increasing carbon concentration. Hardness in steels increases with increasing cementite (Fe3C) concentration. Slow cooling of a 0.76 wt% steel will produce a featuring a PR eutectoid phase. Strength in steels increases with increasing cementite/ferrite interfacial area Marten site is an equilibrium phase of steels.
