Abstract
Abstract Molybdenum alloys containing at least two metallic element components which form a molten alloy which dissolves appreciable Mo during liquid phase sintering may contain additives selected from Co, Mn, Cr, Ru, Zr, Ti, Hf, Re, refractory metals, and metalloids to obtain desired properties for certain applications. Many of these additives are particularly effective in shaping members.
