摘      要：A novel method for testing stress–strain curves of non-metallic materials was *** high temperature stress-strain curves of MnS were preliminarily obtained and corrected to account for the influence of *** the finite element method,the influence of deformation parameters on the deformation evolution of MnS inclusions was investigated based on the experimental reference *** corresponding physical experiment was designed for comparative *** results indicate that the experimental high-temperature deformation data of MnS are highly *** the process of matrix deformation,the shapes of MnS inclusions change from spherical to ellipsoidal and even to *** are some differences in the morphological deformation of MnS inclusions located at different *** the increase in the initial size of MnS inclusions,the risk of failing the inclusion-flaw inspection increases and the forging quality further deteriorates.
