The present article considers forward extrusion, closed-die forging and backward extrusion processes for fabrication of individual microcomponents from two bulk metallic glass (BMG) compositions: Mg 60 Cu 30 Y 10 and Zr 44 Cu 40 Ag 8 Al 8 . Two types of tooling were used in the present work: relativ
This paper presents results based on a series of indentation tests (hobbing) performed on supported billets of Coronze, a superplastic alloy of copper, aluminium, silicon and cobalt. The relationship between hobbing force, depth of indentation and strain rate was established. An upper bound techniqu
