Abstract: A pulsed current source comprises a power source, a discharge capacitor, and an inductive element. The discharge capacitor is selectively coupled to either of the power source or the inductive element. When coupled to the power source, the discharge capacitor is charged. The inductive element can be connected to a load. The load can have a current-dependent impedance. When the discharge capacitor is coupled to the inductive element, the discharge capacitor discharges through the inductive element and the load. The discharge capacitor and the inductive element are configured so that the current through the load exhibits a substantially linear rise in a linear operational region. The inductive element is configured to saturate during discharge of the capacitor through the load, so that the saturation of the inductive element causes the current through the load to continue to rise in a substantially linear fashion.

Abstract: Carbon fiber reinforced steel matrix composites have carbon fiber impregnated in the steel matrix and chemically bonded to the steel. Chemical bonding is shown by the presence of a unique amorphous carbon layer at the carbon fiber/steel interface, and by canting of steel crystal edges adjacent to the interface. Methods for forming carbon fiber reinforce steel composites include sintering steel nanoparticles around a reinforcing carbon fiber structure, thereby chemically bonding a sintered steel matrix to the carbon fiber. This unique bonding likely contributes to enhanced strength of the composite, in comparison to metal matrix composites formed by other methods.
