Abstract
Conventional rolling for reinforced bar comprises of systematic size reduction during manufacturing. During rolling, compressible forces of rolls at every stage is applied for plastic deformation of material. These forces deform the grains as a result of elongated grains and decreased grain size at the final stage of rolling. In this work the grain size and hardness at different stages of rolling was investigated from metallurgical and mechanical perspective. The results showed that the hardness is dependent on grain size and the Hall-Petch equation was employed for the same. For the present study, the calculated Hall-Petch equation is H = 56.98 + 112.51d-1/2.
