MARTENSITIC TRANSITION ENTROPY CHANGE AND ELASTIC CONSTANTS OF Cu-Al-Be ALLOYS

Abstract

Investigations are reported in a number of applications areas for high average power, nanosecond pulsed Diode-Pumped Solid-State Lasers operating at the fundamental wavelength of 1064nm. This includes cutting and polishing polycrystalline diamond and high-speed milling of industrial materials such as aluminium and steels. The results are investigated with regard to processing these materials at superior rates by comparison with conventional technologies. The effects of varying laser parameters are reported with respect to the inter-related phenomena of plasma formation, dimensional accuracy, material removal, dross formation and processed material properties.
