Title: Laser heating of construction materials Keywords: laser heating, temperature, construction materials Abstract: This paper analyzes laser heating processes and their effects on the material thermal response. The radiation-materials interactions are treated as a coupled process as heating of the metal lattice through electron-phonon collisions. Pulse duration, heating intensity and time of heating are key parameters of manufacturing process. The construction materials like cemented carbides, ceramics, metal matrix composites are increasingly attractive because of their superior combination of properties such as high strength, hardness and fracture toughness. These materials are finding potential applications in the manufacture of transport components such as wheel/rail systems, electrical. One of the ways to improve the wear performance of machine parts is application of sintered carbides layer by laser cladding method. The paper under discussion focuses on the analysis of the impact of the laser beam on various construction materials and shows a current trends in laser heating. References Issue
