Abstract (en)
[origin: EP3202953A1] Provided is a titanium cast product made of titanium alloy, the titanium cast product being produced by electron-beam remelting or plasma arc remelting, comprising: a melted and resolidified layer in a range of 1 mm or more in depth at a surface serving as a surface to be rolled, the melted and resolidified layer being obtained by adding one or more kinds of ² stabilizer elements to the surface and melting and resolidifying the surface. An average value of ² stabilizer element concentration in a range of within 1 mm in depth is higher than ² stabilizer element concentration in a base material by, in mass%, equal to or more than 0.08 mass% and equal to or less than 1.50 mass%. As the material containing the ² stabilizer element, powder, a chip, wire, or foil is used. As means for melting a surface layer, electron-beam heating and plasma arc heating are used.
