Abstract
A process of making useful shapes by joining of tungsten alloys. Joining of tungsten heavy alloys which are alloys typically made from W—Ni—Fe is used. These alloys are typically manufactured by liquid phase sintering. This leads to difficulty in producing large length to diameter ratio parts that have some significant weight (such as penetrators). A “brick and mortar” approach is employed wherein smaller segments of this alloy (low length to diameter ratio) are joined to together to produce a larger part with higher length to diameter ratio.
