Abstract
A composite material based on polyethylene terephthalate (PET, about 1% by mass) and Al85Y8Ni5Co2 metallic glass was obtained by mechanical alloying and consequent spark plasma sintering. The spark plasma sintering was performed at a temperature near to the super cooled liquid region of the metallic glass. Mechanical properties and the structural characterization of the composite material were obtained. It was conceived that composite samples (Al85Y8Ni5Co2/PET) have a better thermal conductivity in comparison with pure PET samples. The formation of the crystalline phases causes degradation of physical properties. It was calculated that the activation energy for crystallization of the Al85Ni5Y8Co2 metallic glass is higher than that of the other types of metallic glasses (Mg67.5Ca5Zn27.5 and Cu54Pd28P18) used for composite preparation previously. This denotes a good thermal stability of the chosen metallic glass.
Highlights
The unique properties of composite materials often make them more desirable than pure components
The difference between the thermal conductivity of the composite sample and the metal glass sample is about 50%. This difference is much greater compared to the results presented in our previous works [21,22]
A method was proposed that allows obtaining a composite material based on a polyethylene terephthalate and Al85 Y8 Ni5 Co2 metallic glass
Summary
The unique properties of composite materials often make them more desirable than pure components. A combination of two different materials can result in enhanced properties, such as high strength and good ductility. The reinforcement elements help to improve the mechanical properties [1] of the composites. Metallic glasses have gained attention because of their remarkable properties [2]. They have outstanding corrosion and wear resistance and show unusual magnetic softness [3,4]. The procedure for casting metallic glasses is generally an inexpensive process. Metallic glasses have various applications in optical, electrical, magnetic, and mechanical materials, as well as in membranes, biological materials, and biotechnology [5]
