ABSTRACT:
A method for manufacturing a titanium alloy sheet, which comprises the steps of: covering at least one titanium alloy slab with carbon steel plates, welding together the carbon steel plates by means of a high-energy-density welding under a vacuum atmosphere to prepare a carbon steel envelope, thereby preparing an assembled slab, containing the titanium alloy slab therein, with an interior thereof kept at a degree of vacuum of up to 10.sup.-2 ; applying, prior to preparation of the assembled slab, a release agent comprising a solid content having a particle size of up to 325 mesh, onto the surfaces of the titanium alloy slab or onto the inner surfaces of the carbon steel envelope facing thereto, adjusting the total applying quantity of the release agent so as to satisfy the following formula: 5,000.ltoreq.X.multidot.Y/(1-.sqroot. Z).ltoreq.25,000, where X: weight percentage (wt. %) of the solid content in the release agent, Y: total applying quantity (ml/m.sup.2) of the release agent; and Z: degree of vacuum (Torr) in the interior of the assembled slab; and hot-rolling the assembled slab.
