Buffing Hardness Reduction Laser Peening Ni-Based Alloy 600 Residual stress Water Jet Peening
In order to compare the stability of the stress improvement effect introduced by laser peening (LP), water jet peening (WJP) and buffing residual stress improvement methods during the long-term operation of nuclear power plants, the hardness in nickel-based alloy 600 has been studied through the kinetics of hardness reduction behavior in practical operation temperatures. The predicted hardness results show that in actual operating condition, the time required to reduce the hardness to 180HV is 1268 years fo...

Guide wave Heat exchange pipe High temperature Long waveguide Nondestructive inspection
Various energy plants use a large number of important equipment and structural members that are continuously operated in a high temperature range exceeding 500 ° C. Monitoring and evaluating their remaining life is an important issue that is directly linked to plant safety and economic efficiency. Non-destructive inspection plays an important role in non-destructively evaluating the soundness of structures and the materials that compose them. Therefore, we have developed a non-destructive inspection system ...
