Abstract
The short-range order structure of the liquid Al0.973Ni0.027 eutectic alloy and eutectic based composites with carbon nanotubes containing 5, 10 and 15% was investigated. The changes of the main structure parameters (interatomic distances, coordination numbers, cluster sizes) was analyzed depending on the nanotubes content and temperature of the composites. As a result of the addition of carbon nanotubes, the atomic structure contracting of the liquid Al0.973Ni0.027 eutectic was revealed.
Highlights
The necessity to obtain light and durable materials arose primarily with the development of aircraft and aerospace industries and remains relevant to this day
Ni-carbon nanotubes (CNTs) composite was performed (Fig. 2), which revealed the presence of diffraction peaks corresponding to crystalline nickel
The study of composites structure obtained by the liquid phase sintering method in the liquid state was carried out by analyzing structure factors (Fig. 3), pair correlation functions and parameters obtained from them
Summary
The necessity to obtain light and durable materials arose primarily with the development of aircraft and aerospace industries and remains relevant to this day. It is known that as the strength and stiffness of the materials increases, the dimensions and the mass of the material of the vehicle decreases This promotes to increase the load capacity and reduce the amount of fuel used by aircraft and cars. It is known that metals and alloys cannot have high strength and stiffness values at the same time, which has led to intensive studies of composite materials. In these materials, strength and ductility are provided by a metal matrix and stiffness by filler. Strength and ductility are provided by a metal matrix and stiffness by filler Due to their mechanical, electrical and thermal properties, carbon nanotubes (CNTs) are promising reinforcing materials in composites. The best candidates for this are metals and metal alloys that combine high ductility with durability
