Sintered Part and Method for Producing Same
A sintered part has at least one base with a first end face which faces in a first axial direction and a second end face which faces in a second axial direction. The end faces are produced in a press for producing a green body (which is subsequently sintered to form the sintered part) by applying at least one punch which can be moved along the axial directions. The sintered part has an elevation extending from the first end face towards one end at least in the axial direction over a first height, and the elevation has a first width extending transversely to the axial direction in a radial direction and at least some portions of which are smaller than 0.8 millimeters, wherein at least some portions of the sintered part have a first density along the first width, said density equaling at least 87% of the full material density.

METHOD FOR PRODUCING MOLYBDENUM ALLOY TARGETS
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.

Apparatus and method for internal surface densification of powder metal articles
A method and apparatus for surface densification of powder metal annular preforms is described. A forming tool has external helical teeth corresponding to internal helical teeth of the preform. A die correspondingly configured to the external splines of the preform circumferentially surrounds the forming tool. The forming tool, die and lower punch(es) collectively define an aperture dimensioned to receive the preform. Upper punch(es) encase the preform in the aperture. Surface densification of the internal surface of the preform is achieved by movement of the preform axially over the forming tool. External splines of the preform and corresponding die splines direct the preform axially while internal helical teeth and corresponding forming teeth direct the forming tool to rotate as the preform moves. The forming teeth have varying dimensions in the circumferential and radial directions to apply compression and relaxation to densify the surface of the preform helical teeth.
