Abstract


Toughness and thermal shock resistance of the papers nanocomposite ceramic tool materials research has important theoretical and practical significance of the research and development of robust and high thermal shock resistance is the goal nanocomposite ceramic tool material . Export nanoparticles scales with the expression of the yield strength of the relationship and the critical grain size ; nanocomposite than the expression of the strength of ceramic materials with residual thermal stress relationship and optimum grain crack ; launched nanocomposite ceramic material bridge contribution associated toughening mechanisms ; the toughening contributions to to export the residual stress and the best content of nanoparticles based on residual thermal stress toughening formula ; proposed to seek the unified thermal shock evaluation parameters as the study of the theory of thermal shock system goals ; the critical temperature difference resolution to establish the relationship between the thermal shock resistance and fracture toughness of the nanocomposite ceramic tool material ; establish a finite element model of the thermal shock resistance of nano- composite ceramic materials laser thermal shock simulation ; unsteady temperature field and thermal stress . field laser thermal shock simulation, coordinated and synchronized relationship between the temperature field and stress field obtained ; using software obtained relationship between time curve maximum tensile stress and thermal shock , and the radius of maximum tensile stress with laser heating curve , and raised the heat flux as thermal shock evaluation parameters .
