    • Hydrostatic Extrusion of Metals and Alloys 

      J.J. Lewandowski and A. Awadallah (2013-12-03)
      IN HYDROSTATIC EXTRUSION, the billet is extruded through a die via the action of a liquid pressure medium instead of the direct application of the load through a ram. In cases of hydrostatic extrusion, the billet is ...
    • Solidification During Casting of Metal-Matrix Composites 

      P. Rohatgi; B. Schultz; N. Gupta; A. Daoud (2013-12-03)
      Metal-matrix composites (MMCs) are engineered combinations of two or more materials in which reinforcing phases are dispersed in a metal or an alloy. Structurally, cast MMCs consist of continuous or discontinuous fibers ...
    • Rotary Forging 

      Unknown author (2013-12-03)
      ROTARY FORGING, or orbital forging, is a two-die forging process that deforms only a small portion of the workpiece at a time in a continuous manner. Unfortunately, the term rotary forging is sometimes used to describe the ...
    • Color Metallography 

      George F. Vander Voort (2013-12-03)
      The use of color in metallography has a long history, with color micrographs published over the past eighty-some years. A number of general articles have been published reviewing methods and applications. Natural color is ...
    • Color Metallography 

      Mario Epler (2013-12-03)
      Precipitation reactions are of great importance in engineering alloys. This general phenomenon occurs in many different alloy systems when one phase transforms into a mixed-phase system as a result of cooling from high ...
    • Quantitative Characterization and Representation of Global Microstructural Geometry 

      Arun M. Gokhale (2013-12-03)
      It is the central precept of materials science that processing governs microstructure and the microstructure influences the properties and performance of materials. Consequently, quantitative characterization and mathematical ...
