Abstract: A sputtering target that includes at least two consolidated blocks, each block including an alloy including a first metal (e.g., a refractory metal such as molybdenum in an amount greater than about 30 percent by weight) and at least one additional alloying ingredient; and a joint between the at least two consolidated blocks, the joint being prepared free of any microstructure derived from a diffusion bond of an added loose powder. A process for making the target includes hot isostatically pressing (e.g., below a temperature of 1080° C.), consolidated preform blocks that, prior to pressing, have interposed between the consolidated powder metal blocks at least one continuous solid interface portion. The at least one continuous solid interface portion may include a cold spray body, which may be a mass of cold spray deposited powders on a surface a block, a sintered preform, a compacted powder body (e.g., a tile), or any combination thereof.
