A preliminary study has shown that bulk metallic glasses of the CuZrAl type of large dimension may be manufactured from amorphous powders densified by a process of sintering such as spark plasma sintering (SPS). However, to remedy the lack of plasticity of these materials, the addition of ductile crystalline particles was carried out in the present study. The zirconium was chosen because its properties are close to those of the amorphous matrix. The same sintering parameters as those optimized for the metallic glass are also applicable for the production of the composite for the different zirconium volume fractions retained, respectively 5%, 10%, 20%, 30%, 40% and 50%. The materials obtained are dense. X-ray diffraction clearly indicates that only the amorphous matrix CuZrAl and the crystalline zirconium are present. Young's modulus as well as the elastic limit decrease only very slightly with the addition of crystalline particles. Decrease in hardness is more pronounced. On the other hand, the plastic deformation increases with the addition of zirconium, reaching about 4.9% for the alloy containing 50% zirconium. The analysis of the fracture surfaces clearly shows the role of the ductile crystalline particles, namely the deceleration of the shear bands. The influence of volume fraction and size of the crystalline particles and of matrix toughness is discussed from a mechanical point of view.

Therefore, SPS is a solution to solve both the problem of size and low ductility of amorphous metal, since it is possible to control microstructure and so to control mechanical properties.

初步研究表明，大尺寸CuZrAl型块状金属玻璃可以用无定形粉末制造，该无定形粉末通过烧结工艺（如火花等离子烧结（SPS））致密化。但是，为了弥补这些材料的可塑性不足，在本研究中添加了可延展的结晶颗粒。选择锆是因为它的性质接近于无定形基体的性质。与针对金属玻璃优化的那些相同的烧结参数也适用于复合材料的生产，因为保留了不同的锆体积分数，分别为5％，10％，20％，30％，40％和50％。所获得的材料是致密的。X射线衍射清楚地表明仅存在无定形基体CuZrAl和结晶锆。年轻的' s的模量和弹性极限随晶体颗粒的添加而仅略微降低。硬度降低更为明显。另一方面，塑性变形随锆的添加而增加，对于含50％锆的合金，塑性变形达到约4.9％。断裂表面的分析清楚地表明了韧性晶体颗粒的作用，即剪切带的减速。从机械的角度讨论了晶体颗粒的体积分数和大小以及基体韧性的影响。断裂表面的分析清楚地表明了韧性晶体颗粒的作用，即剪切带的减速。从机械的角度讨论了晶体颗粒的体积分数和大小以及基体韧性的影响。断裂表面的分析清楚地表明了韧性晶体颗粒的作用，即剪切带的减速。从机械的角度讨论了晶体颗粒的体积分数和大小以及基体韧性的影响。

因此，SPS是解决非晶态金属的尺寸和延展性低的问题的解决方案，因为可以控制微观结构并因此控制机械性能。
