Abstract

It was already reported that Al-Ni-Zr amorphous alloys powder was expected to show excellent properties in not only mechanical such as toughness and strength but also abrasion and corrosion resistance. It is also known that those alloys can be produced by Double Mechanical Alloying (DMA) method, which has taken instead of the rapid solidification method. In this study, compacts of Al-Ni-Zr amorphous were formed from amorphous powder mechanically alloyed, by Vacuum Hot Press (VHP) method for various conditions. Densities of compacts were measured and the rupture strength and the deflection were tested in order to know its mechanical properties. As a result, a relative density of the compact increases as compacting pressure increases and it becomes constant until 700-800 MPa, then the particle begins to deform over that pressure range. In this compacting pressure range, for the density is stable, the both of the rupture strength and the maximum deflection become to the maximum value. Below that pressure, consolidation is not packed enough, and above that pressure, the crack inside compact occurs due to over pressure. Therefore, that range of pressure can be thought optimum compacting pressure to form Al-Ni-Zr amorphous consolidation.
