Abstract

The fracture toughness of high-temperature alloy material under high-temperature is tested with the laser moire interfrometric device. The zero-thickness grating is etched on the surface of test piece by electrochemical method directly, expanding the research space of high-temperature alloy’s moire interferometry. The moire fringe is collected and analyzed by CCD imaging system of computer, the test result that indicates imaging quality and measurement precision of moire interferometry are improved.
