Abstract:

An experimental study was done on the wire and sheet production, properties, and applications of zirconium base alloys. Zirconium alloys were melted from an iodide by the consummable arc method under an argon atmosphere into 200-300 g ingots. Sheets were made by hot and cold rolling, using intermediate annealing at 800 degrees C under a vacuum of 1 x 10 to the minus 4th power mm Hg. The scrap percentage was about 15-35 percent, depending on the rolling technique. Wires of 0.8-1.0 mm diameter were drawn by plating with a 2-5 micron coating of copper and using ordinary mill lubricants. Colloidal graphite was far superior to any other lubricant used. The chemical compositions of 10 different alloys were given, along with the coefficient of linear expansion, electrical resistivity, and magnetic susceptibility. Alloys were made with up to 1.1 percent Hf, 7 percent Ti, and 0.1 percent of Al, Be, Si, Mo, V, Sn, Mn, and Re. The properties of technically pure titanium were also given as a comparison. The tensile properties, microhardness, and elastic modulus of the above alloys were presented.
