The use of nanotechnology in the manufacture of castings

Abstract

Nanoscale particles (1 nm = 10-9 m), entered into the melt, allow to obtain castings from iron-carbon and non-ferrous alloys with a homogeneous fine-grained structure in different sections. The use of nanomaterials changes the modes of consolidation of components of composite castings, increases the stability of technological processes, and provides technological reliability of cast parts. The control of the castings structure in the presence of nanoparticles is achieved by the presence of a physical interface with the liquid phase, which determines the heterogeneous crystallization mechanism.
