The Strength of Ferrite in Annealed Armco Iron and Hypoeutectoid Steels

Abstract
The strength of ferrite in an armco iron with varying grain sizes and in five hypoeutectoid steels with varying volume fraction of the constituent phases have been studied using microhardness measurements. In armco iron, the strength of ferrite derived from its proportionality with microhardness, is found to decrease with increasing grain size according to the existing Hall-Petch relations. But the strength of ferrite in hypoeutectoid steel is found to vary considerably, even when the grain sizes in ferrite are almost constant. On the other hand, strength of ferrite in hypoeutectoid steel bears a strong functional relationship with volume fraction of the constituent phases. The variation of strength of ferrite in hypoeutectoid steel is explained on the basis of thermal residual stress exerted by the presence of pearlite.
