To evaluate the lifetime of structural materials utilized in a spallation neutron source, corrosion tests in lead–bismuth eutectic (LBE) have been done at JAEA. Austenitic steels are preferable as the structural material for ADS. However, previous

In high power laser welding, vigorous vaporization of the melt meal and fluctuation of the keyhole induce spatter formation. It is well known that for laser welding of thick plate, the keyhole opening can be enlarged and deepened if a sufficient gas
