| Abstract: | A testing method for the fracture toughness of surface crack at high temperature is proposed. Techniques for heating, temperature control and measuring of crack opening displacement are discussed. The method is effective and employs relatively simple experimental devices. Some testing results for the surface cracks at welding seams of LD10CS aluminum alloy are given. |
