Consolidation of rapidly solidified Mar-M 200 powder was carried out successfully using the axi-symmetric and plane-wave (using contact explosives with normal incidence) geometries. However, cracking produced by reflected waves remains a major problem and considerable development work will be required until it can be eliminated. The ambient temperature ultimate compressive strength of the consolidated powder is approximately 2200 MPa. The change in micro-indentation hardness and microstructure as a function of isochronal anneals of one hour between 600 and 1200° C are presented. Ageing compact to optimum hardness (850° C/1 h) raises the ultimate compressive strength to 2250 MPa.
