The first nuclear power station in Japan (Advanced Calder Hall type, 166MW electric) is now under construction at Tokaimura. Construction of several new nuclear power stations will begin within a few years and also building project of the first nuclear powered ship (6500 G. T.) has been started in 1963. Al-killed steel plates 80∿94mm thick were manually welded for Tokai reactor pressure vessel and its steam raising units were constructed with 54∿74mm thick boiler plates using both submerged arc and manual welding. JPDR is a small BWR (12.5MW electric), and the inner surface of its pressure vessel was stainless steel cladded by submerged arc process. Researches on the welding of the nuclear reactor have been extensively carried out by Japan Welding Engineering Society and also each industrial plant is doing its own researches. The study on the effect of irradiation on the properties of materials has been just started.

In this research, diffusion bonding of the intermetallic compound TiAl containing Fe, V, B and SACM645 steel was investigated. Relationships between strength characteristics and bonding parameters were analyzed. Main results obtained are as follows, (1) Direct diffusion bonding of TiAl and SACM645 was possible, high strength joints were obtained by selecting short bonding time with the bonding temperature in the range of 1223〜1283K.(2) In the bonding interface, two or three inter-layers were formed as diffusion process proceeded. Decarburized layer at the steel side, Fe-Al-Ti type layer and TiC layer at the TiAl side were formed.(3) High strength joints were obtained by suppressing the formation of TiC compound in the bonding interface and by controlling total width of inter-layers within 5μm.

Intensity of secondary electron induced by incident electron beam depends on a degree of inclination of surface. In the present work, 3-dimensional image for fracture surface was tried to constitute by applying this secondary elecron property with improved type SEM equipment which had four secondary electron detectors to remove a image distortion caused by observating direction. As the results, we could obtain 3-dimensional image and measured direction depth of fracture surfaces by real time treatment with 32 bit personal computer. In the case, the calculation time for one fractograph analysis was about only 5 minutes.

The dissimilar materials welded joints of high manganese non-magnetic steel/carbon steel(hereafter refered to as DMW joints), in which weld defects such as hot crack or blowhole are not found, were the good quality. Tensile strength of DMW joints was 10% higher than that of the base metal of carbon steel. In the bend tests, the DMW joints showed the good ductility without crack. Charpy absorved energy at 0 (℃) of the DMW joints was over 120 (J) in the bond where it seems to be the lowest. Large hardening or softening was not detected in the heat affected zone. Fatigue strength of the DMW joints is almost the same with that of the welded joints of carbon steel/carbon steel. As the fatigue strength of the DMW joints exceeds the fatigue design standard curve of JSSC for carbon steel welded joints, the DMW joints can be treated the same as the welded joints of carbon steel/carbon steel of which strength is lower than that of high manganese non-magnetic steel, from the viewpoint of the fatigue design.

This study was carried out quantitatively to evaluate the hot cracking susceptibilities of various Ni-base superalloys and the effect of grain size on hot cracking susceptibility during laser welding. Ni-base superalloys used were Inconel 718,Inconel X-750,Inconel 617,Inconel 625,Nimonic 90 Waspaloy, Hastelloy X. The grain size of Inconel 718 varied from about 10 to 110 μm. In this study, the hot craking susceptibility was evaluated by a modified U-type hot cracking tester during CO_2 laser welding. Samples were solution heat-treated before welding and welded with laser powers of 3 and 5 kW and with a traveling speed of 0.5 to 3 m/min. The hot cracking occurring in the weldment during the bead on plate test was reproduced on the U-type hot cracking test. Consequently, the liquation cracking susceptibilities of various Ni-base superalloys decreased in the order of Waspaloy, Inconel 617,Inconel 718,Hastelloy X, Inonel 625,Inconel X-750 and Nimonic 90. Liquation cracking susceptibility of Inconel 718 increased with an increase in grain size.
