Advanced fast breeder reactor Creep damage Energy structural materials ferrite Magnetic force microscope Microcharacterization SUS316FR Welded specimen
Creep tests for energy structural materials of austenitic stainless steel SUS316FR were performed. And degradation mechanism of welded specimen was investigated by using microcharacterization technique of magnetic force microscopy. In as-received specimen, magnetic phases of S-ferrite were interconnected at weld metal region. While in crept specimen, the magnetic phases at weld metal region were isolated, and the amount of magnetic phases decreased. It was found that creep da mage of welded specimen could ...

AE analysis CFRP damage mechanism degradation fatigue test HAZ laser cutting micro X-ray CT tensile test
Carbon fiber-reinforced plastics (CFRP), which is expected to reduce the weight or increase the efficiency of transportations and energy products, was cut by an CO2 gas laser (10.6um, 800W, 20kHz, 8us, 1m/min), CW single-m ode fiber laser (1.07um, 300W, 2000W, CW single-mode, 1m/min, 7m/min) and machining with milling. Although the high-power laser cutting processes make it possible to improve cutting rate of CFRP, the laser-cut specimens cl early showed a thermal damage with a heat-affected zone (HAZ) ide...
