摘要： A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

摘要： An apparatus and method for hybrid machining a workpiece is disclosed. The workpiece is powered as an anode, a cutter is powered as a cathode and a cutting fluid or coolant is circulated therebetween. The cutter is made of a conductive material and a non-conductive abrasive material. The hybrid machine performs a roughing pass machining operation in which material is removed from the workpiece at a relatively high rate using a high-speed electro-erosion (HSEE) process. Then, the hybrid machine performs a finish pass machining operation in which material is removed from the workpiece using precision electro-grinding (PEG) process at a different differential electrical potential and/or flushing rate than the roughing pass machining operation to provide a smooth finish without thermal effects on the workpiece.

摘要： An EDM wire having an outer coating of epsilon phase brass and a process for manufacturing the EDM wire is provided. The process includes coating a copper bearing metallic core with zinc. The zinc coating is then converted to epsilon phase brass by heat treating the wire at a temperature low enough to minimize or eliminate any resulting changes in the mechanical properties of the wire. The coated core wire may be drawn to a finish size prior to heat treatment which will result in a wire with a substantially continuous epsilon phase coating.
