The self-propagating foaming process of porous Al-Ni intermetallics was investigated. Aluminum and nickel powders were blended, and titanium and boron carbide powders were added as reactive exothermic agents. The blended powder was extruded to make a rod-shape precursor. Only one end of the rod precursor was heated to ignite the reaction. The reaction propagated spontaneously throughout the pre...

The ablation material used during the National Ignition Campaign, a glowdischarge polymer (GDP), does not couple as efficiently as simulations indicated to the multipleshock inducing radiation drive environment created by laser power profile [1]. We investigate the performance of two other ablators, boron carbide (B4C) and high-density carbon (HDC) and compare with GDP under the same hohlraum c...

Nanocomposites based on boron carbide B4C are hard materials with wide field of applications in modern technologies. A system first-order ordinary differential equations that simulates the process chemical synthesis nanopowders B4C–TiB2 compositions containing titanium diboride (TiB2) as an additional phase is suggested and resolved numerically for a typical ratio reaction constants. Reagents p...
