抄録

As the first step to improve Magnox series alloys currently used in Calder Hall power reactor in England as well as to develop better magnesium alloys to be used for canning materials in CO2 gas-colled reactor, the following experiments have been carried out:<br>By preparing, in the authors own laboratory Magnox E alloy, as well as several Mg-Al-Ca-Be alloys of different amount of calcium and berylium, but less than those in Magnox E, the effect of the two elements on the properties of the alloys have been confirmed. The two elements improved strength and oxidation resistance; calcium being more effective in strengthening as seen in Fig. 1.<br>Substitution of calcium with other element of lower thermal neutron absorption cross section (less than 1 barn) was the subject of next concern, as calcium is not recommended because of welding crack problem. Work hardening characteristic and annealing curves shown in Fig. 2 and 3, respectively have been compared and little differences has been found in the former among the candidate alloys without calcium. Considering from the annealing curves, the high temperature strength at the working temperature of reactor, 752°F (400°C), may be improved by the addition of zirconium, zinc or bismuth, about which further experiments are being contemplated.
