Gopi Krishna Assistant Professor Dept of Mechanical Engineering Acharya Nagarjuna University ABSTRACT Experiments on cold deformation behaviour are conceded out on as cast and homogenized coal ash Silicon carbide composite billets. The study was intended to evaluate the effect of reinforcement percentage on the deformation behaviour. The mechanical properties like hardness tensile behavior modulus of elasticity yield stress have been carried out. The microstructures were taken from SEM to examine the distribution of ash and SiC particulates in the matrix. The deformation process is carried out between two flat platens and sample at the center to envisage the metal flow at room temperature. To observe the changes in hardness after deformation the hardness measurements were carried out to examine the changes after the forging. It is observed from the experimentation that the circumferential stress σθ has positive values tensile with unremitting deformation. As the barreling initiates the axial stress σz will get compressive values. The effect of strength coefficient and strain hardening behaviour with the sample deformation and barreling effects have been calculated.
