Validating Models Using 3D Microstructural Characterization R.W. Fonda and D.J. Rowenhorst In order to take full advantage of the promise of recent computational efforts, new microstructural models that consider realistic shapes, connectivities, and distributions are required. This can only be achieved through 3D characterization. Structural Intermetallics: Alloy Design, Processing, and Applications John H. Perepezko, Bruce A. Pint, and David R. Forrest Structural intermetallics offer a number of attractive choices to address an urgent need for materials that can endure harsh environments for extended periods. Combustion Driven Powder Compaction Green Manufacturing Enables Higher Performance Parts Karthik Nagarathnam and Dennis Massey A new and economical method produces near-net and net shape high-density powder metal components at higher compaction pressures than traditional processes. METALLURGY LANE Aluminum: The Light Metal—Part I Charles R. Simcoe Aluminum, one of the most widely used structural metals in modern industry, is produced in quantities exceeded only by steel. Its light weight, corrosion resistance, high strength after heat treatment, and global availability of bauxite ores make aluminum attractive for everything from kitchen utensils to spacecraft. Materials Science & Technology 2014 Show Preview MS&T is the leading forum addressing structure, properties, processing, and performance across the materials community. This year’s conference in Pittsburgh will bring together the brightest minds in materials science and engineerin g.
