The poor corrosion resistance of recent samples press-clad with 6,000 psi at 950 F is believed to have been due to the presence of a large number of stringers intersecting the surfaces of the uranium cores. A better quality metal and an improved pinch-weld will be used in the future. Machining of extrusion dies and mandrel tips by Moczik for the BMI extrusion cladding work is expected to be completed about mid-July. The first attempt to clad the internal surface of a tube by ``hot drawing`` has been completed. A plug was drawn through an aluminum billet placed in the tube and heated to 955 F. A weakly bonded cladding with a poor surface was produced. Several uranium-aluminum billets have been cast into a water-cooled steel mold as a means of varying the cooling rate of the alloy. Billets previously cast into a graphite mold are being examined by radiography in order to determine the effects of the rate of solidification on the segregation of the alloy.
