A method is outlined for making a reactor control rod with higher strength properties (yield strength>l5,000 psi at 550 to 600-F) and suitable for use in military and naval reactors. The method comprises forming a fine powder of an alloy composition with a thin oxide coating, preparing a sintered billet from the powder, and shaping the billet to result in a control rod with an oxygen content of 0.1 to 0.3 wt%. The alloy composition consists of 65 to 85 wt% Ag, 2to 20 wt% In, 0to 10 wt% Cd, 0to 5wt% Sn, and0to l.5 vt% Al; the amounts of each metal employed is determined by the equation X + 2Y + 3Z + 3W + 4V = l.4to 1.3, where X, Y, Z, W, and V are the atom fractions of Ag, Cd, In, Al, and Sn, respectively. Creep-rupture data are given for this material. (D.L.C.)
