Abstract: The present invention relates to a method for producing a molybdenum alloy target, and solves the problem of low density and coarser grains of the molybdenum alloy targets in the prior art. The present invention comprises subjecting a mixed powder with a mass ratio depending upon the formula composition of a molybdenum alloy to a pre-press forming process to obtain a preformed molybdenum alloy target blank; placing the preformed molybdenum alloy target blank in a capsule and subjecting the capsule to processes of preheating for degassing and vacuum seal welding; subjecting the target blank to a hot isostatic pressing process to obtain a densified molybdenum alloy prefabricated target; removing the capsule; and subjecting the molybdenum alloy prefabricated target with the capsule removed to a temperature-rising and pressure-decreasing process, followed by finish machining to obtain a molybdenum alloy target.

Abstract: A system and corresponding method for additive manufacturing of a three-dimensional (3D) object to improve packing density of a powder bed used in the manufacturing process. The system and corresponding method enable higher density packing of the powder. Such higher density packing leads to better mechanical interlocking of particles, leading to lower sintering temperatures and reduced deformation of the 3D object during sintering. An embodiment of the system comprises means for adjusting a volume of a powder metered onto a top surface of the powder bed to produce an adjusted metered volume and means for spreading the adjusted metered volume to produce a smooth volume for forming a smooth layer of the powder with controlled packing density across the top surface of the powder bed. The controlled packing density enables uniform shrinkage, without warping, of the 3D object during sintering to produce higher quality 3D printed objects.

Abstract: Support structures are used in certain additive fabrication processes to permit fabrication of a greater range of object geometries. For additive fabrication processes with materials that are subsequently sintered into a final part, an interface layer is formed between the object and support in order to inhibit bonding between adjacent surfaces of the support structure and the object during sintering.
