Abstract
PURPOSE:To manufacture a Zr-base alloy excellent in corrosion resistance, by applying hot extruding treatment to a Zr-base alloy stock and then subjecting the resulting extruded material to beta-hardening treatment in a state of a specific reduced thickness and further to heat treatment including intermediate rolling treatment. CONSTITUTION:A Zr-base alloy ingot is successively subjected to beta-forging, solution heat treatment, machining, and then hot extruding treatment. The resulting extruded material is subjected to beta-hardening treatment and then to annealing including intermediate rolling treatment, by which a thin nuclear fuel element is prepared. In the above- mentioned method for manufacturing the Zr-base alloy, the above beta-hardening treatment is carried out in a state where the thickness of the Zr-base alloy stock is regulated to <=50mm. Further, in the case of a pipe stock for clad pipe for nuclear fuel elements, it is preferable to carry out beta-hardening treatment by reducing the thickness of the pipe stock to 50-10mm. By the above procedure, hardening effects are allowed to reach the inner part of the stock and satisfactory cooling velocity is secured, by which crystal structure is refined and uniformized. By this method, Zr-base alloy products excellent in corrosion resistance to nodular corrosion can be obtained.
