steels - eutectoid steel, hypo and hypereutectoid steels - effect of alloying elements on the Fe-C
system - diffusion in solids - Fick's laws - phase transformations - T-T-T-diagram for eutectoid steel –
pearlitic, baintic and martensitic transformations - tempering of martensite – steels – stainless steels –
cast irons.
UNIT III MECHANICAL PROPERTIES 9
