説明

A topographical observation system with a scanning laser microscope has been newly developed. This system is consisted of a scanning laser microscope, a personal computer having video-capture equipment and an automatic X-Y stage. We applied this system to a 3-dimensional fractography of TiAl creep-cracked specimen and constructed a 3-dimensional image covered a wide area on fracture surface. Furthermore, we tried to simulate a fracture process by using topographical data obtained through this system. Since creep crack initiation and creep voids nucleation around the creep crack were clearly reproduced, the reliability of this simulation system was confirmed.
