A -- OBJECTIVE INDIVIDUAL COMAT WEAPON (OICW) WARHEAD SOL DAAE30-99-R-0533 DUE 031899 POC MARGARET RHINESMITH, PROCUREMENT TECHNICIAN, 9973)734-3050 WEB: US ARMY TACOM-ARDEC Procurement Network, http://procnet.pica.army.mil/cbd/RFP/99R0533/99R0533.htm. E-MAIL: MARGARET L. RHINESMITH, mrhines@pica.army.mil. The U.S. Army TACOM-ARDEC is contemplating a sole source purchase order to Lambda Research Inc., 5521 Fair Lane, Cincinnati, OH 45227 to provide the Government with a small scale effort to investigate the effect of residual stresses on the fragmentation characteristics of the powder metallurgy tungsten alloy OICW warhead (90% Tungsten, 8% Nickel, 2% Iron). The contractor shall develop an x-ray diffraction technique for measurement of residual stresses in the warhead, and measure the stresses at various locations and through the cross section of current developmental warheads. The contractor shall develop a finite element model of the stress state set up by quenching from high temperature. The contractor shall develop quenching, burnishing and shot peening techniques to create significant compressive stresses on the warhead's outer surface, and measure the stress states set up by his techniques. See numbered Notes 22 and 26. Posted 03/03/99 (D-SN304276). (0062)
