Abstract Ultrasonic processing of solidifying metals in additive manufacturing can provide grain refinement and advantageous mechanical properties. However, the specific physical mechanisms of microstructural refinement relevant to laser-based additi

Copper (Cu) has been patterned using a laser direct-write metallization technique for fabrication of printed wiring boards. The approach consists of writing a silver (Ag) seed layer with a subsequent step of electroless Cu plating to increase thickne

The formation of a directionally solidified non-oxide eutectic surface layer based on the 75 mol% B4C and 25 mol% TiB2 eutectic composition has been developed using a continuous-wave, high-power, CO2 laser. To prevent the oxidation of nonoxide compou

Aluminum matrix composites with reinforcement of planar-random graphite fibers, SiC whiskers, or alumina particulates have been evaluated for their high temperature performance. The composites were aged at 150 and 200°C for up to 500 hours. Microhar

The hardening rates of 6061/SiC/20w and 6061/Al2O2/15p are significantly higher than that of wrought 6061 Al. The whisker composite retains its tensile strength over a broad range of aging times (up to 500 hours). Under identical aging conditions, th

For rapid prototyping and repair of printed wiring boards, direct laser patterning techniques of Cu are investigated. Laser direct writing techniques reported in the literature are compared and contrasted. The approach taken in this work is laser-ind

Design of laser welded sandwich panels has not considered the welds as part of the analysis. The preferred method of failure based on the design, is by global panel buckling. In order for this to occur the welds must be sufficiently strong. The goal

Recent advances in laser technology has enabled the achievement of high power and high quality beams by diode pumping of Nd:YAG slabs. TRW, under the Precision Laser Machining Program funded by DARPA, has produced a 3 kW diode pumped Nd:YAG slab lase
