    Abstract: An aluminum based metal matrix composite is produced from a charge containing a rapidly solidified aluminum alloy and particles of a reinforcing material present in an amount ranging from about 0.1 to 50 percent by volume of the charge. The charge is ball milled energetically to enfold metal matrix material around each of the particles while maintaining the charge in a pulverant state. Upon completion of the ball milling step, the charge is consolidated to provide a powder compact having a formable, substantially void free mass. The mass is then subject to a heat treatment during which it is solutionized at a temperature above the solvus temperature of the alloy, quenched and age hardened at a temperature below the solvus temperature of the alloy to promote precipitation of a primary strengthening Al.sub.3 (Li,Zr) phase and to precipitate substantially all of the Al.sub.3 (Li,Zr) phase into the metal matrix. The composite is especially suited for use in aerospace, automotive, electronic, wear resistance critical components and the like.

    Abstract: A process for making sintered metal articles of high strength in which a flowable mass of metallic particles is initially formed into a green compact having shape stability in a forming machine of the type used in the fabrication of sand cores in the metal casting field. The green compact is then subjected to sintering and the sintered body may be pressed, forged or mechanically shaped in other ways. The core blowing or core-sand slinging machine used to produce the green metal compact is surprisingly effective in producing a dense, reproducible structure in light of the fact that sand cores for casting purposes are intentionally made frangible to enable them to be removed effectively from the casting.

    Abstract: Strongly bonded aluminous bodies with produced by powder metallurgy by blending an amount of nickel powder with aluminum powder at least sufficient to effect the exothermic sintering of a pressed compact of the blended powder by heating the compact in a furnace maintained at a temperature below the eutectic temperature of the aluminum-nickel system and higher than the temperature at which nickel reacts exothermically wth aluminum.

    Abstract: A METHOD FOR PRODUCING SOLID BODIES FROM POWDERED MATERIAL BY THE USE OF EXPLOSIVE FORCES. THE FORCES INVOLVED ARE OF SUFFICIENT MAGNITUDE AND OTHER PARAMETERS ARE SO CHOSEN THAT COMPLETE FUSION OF THE PARTICLES OF THE POWDERED MATERIAL TAKES PLACE TO PRODUCE BODIES OF PURE METAL OR COMPOSED OF ALLOY OR MIXTURE COMPOSITIONS OF TYPES NOW KNOWN AS WELL AS THOSE BEYOND THE RANGES PRESENTLY AVAILABLE, PHYSICAL PROPERTIES SUPERIOR TO THOSE PREVIOUSLY KNOWN AND WHICH MAY BE COMPOSED OF METALLIC OR OF METALLIC AND NON-METALLIC MIXTURES. THIS IS IN CONTRAST TO PRIOR ART METHODS WHICH USE RELATIVELY LOW MAGNITUDES OF EXPLOSIVE FORCES TO ACHIEVE ONLY MECHANICAL COMPACTIONS.
