Brazilian Disc Experiments on a Cold Spray Material

ORAL

Abstract

Characterisation of novel materials presents a number of unique difficulties to the experimenter, however these are problems which must be overcome in order to effectively utilise such materials in systems level applications. A series of experiments were performed to probe the tensile behaviour of a two cold sprayed composite materials containing a mixture of nickel, aluminium, tungsten and zirconium. Data were acquired at two different strain rates and collected using high speed photography, strain gauges, force-extension measurements and digital image correlation techniques. Comparisons were made with modelling on representative microstructural elements in the CTH code.
