    摘要： Methods and apparatus for forming a plurality of uniformly sized solder balls utilize a stencil having a plurality of holes of uniform volume disposed on a substrate. Solder is disposed in the holes of the stencil on the substrate. Typically, the solder is in the form of solder paste which is distributed into the holes using a squeegee. While within the holes of the stencil on the substrate, the solder is melted to form solder balls. The stencil may then be removed to leave the solder balls on the substrate, or the solder balls may be removed while the stencil remains on the substrate.

    摘要： Numerous products can be formed by combining a low melting matrix made up of one or more metals and high melting, high density metal particles and wherein the products can be formed by adding the high density particles to a molten matrix metal and casting same, mixing powders of all the metals together, compacting and centering at a temperature in the low end of the melting range of the matrix alloy, or by mixing the high density particles into a paste of the matrix alloy and molding. These methods and compositions are particularly adaptable for use in forming low or non-toxic high density projectiles, such as, shot, bullets and pellets having a density comparable to that of lead while avoiding problems of toxicity associated with the use of lead.

    摘要： The present invention relates to a Si-containing high-strength and low-modulus medical titanium alloy, and an additive manufacturing method and use thereof. The additive manufacturing method comprises alloy ingredient design, powder preparation, model construction and substrate preheating, and additive manufacturing molding; wherein the Si-containing high-strength and low-modulus medical titanium alloy is designed in the ingredient proportion of Ti 60-70 at. %, Nb 16-24 at. %, Zr 4-14 at. %, Ta 1-8 at. %, Si 0.1-5 at. %. The principle of the present invention is design of a medical β-type titanium alloy having high-strength and low-modulus and good biocompatibility by using d-electron theory; reducing the difference of thermal expansion between the silicide and the β-Ti phase by preheating, and at the same time, ensuring that there is a sufficient degree of cooling in the additive manufacturing process to promote the transition of the alloy from the divorced eutectic reaction to the precipitation reaction, thereby solving the common problems, such as the deterioration of mechanical properties caused by the continuous distribution of the Si-containing phase along the grain boundary and the cracking caused by the difference of thermal expansion coefficient between different phases.

    摘要： A manufacturing method of minute metallic spheres of the present invention comprises a heating means for heating and melting a metal to form a metallic sphere, a measurement means for measuring the injected molten metal into a predetermined volume, and a cooling means for cooling the molten metal discharged from the measurement means, to a temperature less than the melting point. The measurement means has a gauger of a predetermined volume in which the molten metal is injected, and is constructed such that the molten metal is cut by rubbing by the predetermined volume by sliding this gauger in contact. The molten metal is injected in the gauger of the predetermined volume to measure, and the measured molten metal is discharged from the gauger to cool to a temperature less than the melting point, and solidified into a sphere in the cooling process.

    摘要： A procedure for making zinc particles of a size, shape and composition such that the particles can be subsequently used in a process for manufacturing zinc parts from such particles in either molten or powder form includes the initial step of heating zinc to a temperature at least as high as 720.degree. C. The molten zinc is passed through a screen having small openings, on the order of about 1/4".times.1/4" into a cooling region formed by a movable surface which is at a temperature of on the order of about -200.degree. C. The zinc forms small particles as it passes through the openings in the screen and essentially instantaneously solidifies as it contacts the movable surface. Thereafter, the solidified zinc particles are subjected to a grinding process to reduce their size to a powder having a surface area in the range of 2 mm.sup.2 to 20 mm.sup.2.

    摘要： Method and apparatus for the production of metal granules from a molten metal are disclosed. A molten metal stream is directed against an impact element located above the surface of water in a water tank. The impact of the molten metal upon the impact element causes the molten metal to disintegrate into drops which spread out radially from the impact element. The drops fall down into the water below the impact element in an annular region a certain radial distance from the impact element. The radial distance is varied by varying the velocity of the molten metal stream relative to the impact element at the instant of impact, and/or by varying the height of the impact element above the water surface, in order to substantially continuously vary the radius of the annular region in which the molten metal drops hit the water surface.By using the method and apparatus of the present invention it is possible to granulate metals and metal alloys having a low sinking rate in water and a high enthalpy.
