Abstract Using a numerical simulation we investigated the distribution of the shear strains appeared in the Ni3Al intermetallic compound billet during its crystallization under high temperature synthesis from a powder mixture under uniaxial compression. The pressure varied from 326 to 434 MPa. The grain size distribution in the produced billet was measured experimentally. It was found that both maximal values of the shear strains and minimum grain size occur at the edges of the billet. The agreement between the distributions of the simulated shear strains and experimentally obtained grain size suggests correctness of the model used.
