Abstract:

The primary objective of order subcontract was to prepare AGT and UGT test specimens, provide characterization data and provide damage assessments on tech base laser mirror materials being developed on other government contracts. The properties to be determined included flexural strength, Youngs modulus, Poissons ratio, fracture toughness KIc, coefficient of thermal expansion, thermal diffusivity, hardness, and specific heat. In some cases scanning electron microscopy SEM, x-ray diffraction XRD, energy dispersive x-ray analysis EDAX, and Auger spectroscopy AES were to be performed to determine chemical composition and crystal structure and damage mechanisms. In addition if materials problems occurred, that could not be anticipated in advance, studies were to be initiated to aid the SDI optical materials efforts as required.
