    MgAl2O4 spinel powder compacted under room and elevated temperature, are subjected to hot isostatic pressing followed by property evaluations. Though the samples, processed through both the routes have identical densities, mechanical properties are superior for cold compacted samples in comparison to hot compacted samples which have exhibits better optical transmission. Results are also correlated with processing conditions.

  3. Response to Comment on “An Experimental Study on Evolution of Grain-Scale Stress/Strain and Geometrical Necessary Dislocations in Advanced TA15 Titanium Alloy during Uniaxial Tension Deformation”

    Calculation processes of stress/strain obtained from electron backscatter diffraction and geometrical necessary dislocations (GND) density in TA15 titanium subjected to uniaxial tensile deformation are investigated. The similarity between kernel average misorientation (KAM) images and GND distribution images are compared and explained.

    Nickel foam sheet and aluminum solid sheet for battery tab and catalyst support are successfully joined via ultrasonic spot welding. The foam undergoes acceptable thickness reduction and deformation, whereas most of the porous structures remain intact. The mechanical and electrical properties of joints welded at different energies are studied. The welding process is in solid state.

  5. An Approach Toward Numerical Investigation of the Mechanical Behavior of Ceramic Foams during Metal Melt Filtration Processes

    This article describes a numerical modeling approach to investigate the thermomechanical behavior of ceramic foams during metal melt filtration processes. The described methods cover the creation of the geometric models, the fluiddynamic simulations of the melt flow using the lattice boltzmann method, and subsequent finite element simulations.
