STRUCTURAL AND MECHANICAL PROPERTIES OF A Cu//6//0Zr//4//0 (at %) ALLOY PROCESSED BY HIGH VELOCITY INJECTION (HVI).

In the HVI process, alloys are arc-melted in a watercooled copper crucible and injected (at high velocities) into a circular channel by a gas/vacuum coupled pressure gradient. The molten jet rapidly solidifies, as it is in good thermal contact with the circular walls of the copper channel. This process (melting and injection) is carried out in the inert protective atmospheres (helium). The samples produced are in the form of cylindrical rods with large length to diameter ratios (40:1). The samples exhibit a good surface finish and are of high density. Results presented in this paper show that amorphous samples can be produced using the HVI process.
