Abstract:In metal rolling processes, internal holes or cracks can result in unqualified products. This paper evaluates the possibility of cracking in three-roll planetary rolling of bismuth-containing stainless steel bar by combining experiments, finite element simulations, and theoretical modeling. Stress-strain data obtained from hot compression experiments were used to draw hot processing maps after modification. The prediction results of several standard ductile fracture criteria were compared, and it was found tha… Show more
