Thereafter, the alloy is processed by the cold forming with 5-25% reduction of area in a manner to have similar cross sections before and after the process. Further, the allay is treated by the profile plasticity process with 50-60% reduction of area so that the cross sections are made different before and after the process. Subsequently, age hardening is carried out at 550-600 deg.C.

CONSTITUTION: A powder of such a high melting point metal as W or Mo is press- formed into a compressed powder blank which is then baked in a hydrogen atmosphere; an electric power is then conducted across this baked blank which then generates a resistance heat and is sintered thereby. This sintered blank is again heated in a hydrogen atmosphere and is subjected to a hot forging pass; hereby, the blank is deformed into a wedge shape with a taper angle of about 20 degrees after once passing a sheet shape. This wedge shape blank is heated in a hydrogen atmosphere and is hot rolled into a sheet shape. By the present constitution, any creack does not generate in the surface of the sheet product so that the rolling yield of the sheet product is improved.
