Description

technical field [0001] The invention belongs to the fields of material science, high-temperature experimental mechanics, solid mechanics, etc., and relates to a material controllable high-temperature test device and method based on laser irradiation. Background technique [0002] In aerospace, weapons, shipbuilding and other industrial fields, some structures (such as turbine blades and muzzles) are often exposed to high-temperature environments, and their deformation and damage characteristics in high-temperature environments are important indicators for evaluating their life. It is necessary to understand the mechanical properties of the corresponding materials under high temperature environment. [0003] At present, for testing the mechanical properties of materials at high temperatures, the test pieces are mainly heated through a high-temperature box or a heating furnace, and combined with a material testing machine to obtain the mechanical properties of the test pieces....
