[en] Full text: In the past two decades, metallic glasses (MGs) have drawn considerable attention due to their unique mechanical behavior and high corrosion resistance. Cu-based MGs are known for having excellent mechanical properties together with a high glass forming ability. These characteristics make these alloys important candidates for practical applications in structural areas such as “microengineering”, such as the fabrication of micrometric parts. Some quaternary Cu based alloys, such as those belonging to the Cu-Zr-Al-(Nb, Y, Gd) and to the Cu- Zr-Hf-Al systems, presented a higher GFA. Cu-Zr-Al-Y system, have been shown unusual high GFA Cu46Zr42Al7Y5 alloys have shown critical casting thickness up to 1 cm and a ΔTx of around 100 K. Considering these aspects, large BMGs can be produced by consolidation from amorphous powders. This alloy was used in this work to produce powders by gas atomization. The powder with granulometric range of 75 to 106 μm were consolidated by conventional powder metallurgy, (Pressing and Sintering - PS) in the super-cooled liquid region at temperature (420-470 °C) using a H13 steel die with diameter of 1 inch and pressure of 700 MPa. The microstructural and thermal behaviors of the powders and the consolidated amorphous bulk were characterized by X-ray, scanning (SEM) and transmission (TEM) electron microscopy and differential scanning calorimetric (DSC) techniques. The porosity was measured by optical micrographs analysis using the Image J® free software. The mechanical properties were analyzed by HRC microhardness. The consolidation process produces fully amorphous cylindrical samples with 25.4 mm diameter (1 inch) and 6 mm height. The amorphous material showed hardness of ~ 51 HRC and high porosity and it is necessary to study new process parameters to improve the densification. (author)
