摘要： For producing titanium clad steel plates by hot rolling, oxide of Mo or V is used as an intermediate material, and a slab assembly is formed with ferrous bases and titanium cladding materials. At least one side of cladding surfaces of the bases and the cladding materials is coated with an oxide of Mo or V of 20 to 300 g/m.sup.2, and an interior of the slab assembly is air-discharged less than 10.sup.-1 torr, and the slab assembly is heated at temperatures between a melting point of the employed oxide plus 50.degree. C. and 1050.degree. C. and undertaken with hot rolling.

摘要： Disclosed is an aluminum alloy sheet having a chemical composition of an Si-containing Al--Mg--CU alloy. The aluminum alloy sheet exhibits a streak-shaped modulated structure at a diffraction grating points of an Al--Cu--Mg--system compound in the electron beam diffraction grating image. The above mentioned streak can be generated efficiently when the alloy essentially consists of 1.5 to 3.5% by weight of Mg, 0.3 to 1.0% by weight of Cu, 0.05 to 0.6% by weight of Si, and the balance of Al and inevitable impurities, and the ratio of Mg/Cu is in the range of 2 to 7. The alloy contains 0.01-0.50% of at least one element selected from the group consisting of Sn, Cd, and In.
