There is provided an improved process for isothermal shaping of a titanium-containing workpiece in a hot die. A precoat lubricant composition including a glassy component and a solid lubricant such as graphite dispersed in an organic medium is applied to the workpiece, and the workpiece heated to a temperature sufficient to remove the organic medium to leave a residue of glassy material and graphite on the workpiece. The workpiece is then inserted in a heated split die, and the die loaded to alter the shape of the workpiece. The ratio of the solid lubricant to the glassy component is at least one to one. The particle size of the glassy component is important to the surface character of the finally shaped workpiece.
