Hot Rolling of Sendust

Abstract

Deformability by hot rolling of Sendust with the nominal composition of 9.6% silicon, 5.4% aluminum and balance iron has been investigated as a function of hot rolling temperature and reduction per pass. It was found that under the optimum rolling conditions Sendust became ductile and was hot rolled without grain boundary cracking or cleavage cracking. The optimum rolling conditions are consistently derived from conditions of ductile deformation in tensile or bending tests at the lower strain rate region.
