专利汇可以提供Working method of ni-w-base alloy cast ingot专利检索,专利查询,专利分析的服务。并且PURPOSE: To break the cast structure of a cast ingot of an Ni-W-base alloy contg. a specific amount of W, and considerably improve workability by sealing said ingot into a metal vessel then hot-pressing the same at specific temperatures.
CONSTITUTION: A cast ingot 1 of an Ni-W alloy contg. 5W35% W in weight which is the cathode material for electronic tubes such as vacuum tubes or cathode ray tubes or an Ni-W-base alloy added with a slight amount of one or more kinds of AlC, Mg, Si, Zr, etc. to this is sealed into a metal vessel 2. Metal-made covers 3 are welded to the vessel 2 by electron beams in a vacuum to seal both ends thereof, thence the cast ingot 1 is annealed to be homogenized. Thence, the cast ingot 1 is pressed in the arrow direction normal to its longitudinal direction at 900W1,350°C temperatures. If the reduction of area is made about ≥30% by this hot pressing, the cast structure may be broken down.
