Estudio de las propiedades térmicas de los materiales.

Abstract

The properties of materials in engineering are very important, such is the case of thermal conductivity which indicates their thermal capacity to conduct heat. When machine elements operate in hot environments, heat transfer can affect machine performance. Therefore, the study of the parameters in the changes in thermal properties will help a better understanding and adequate selection of materials in engineering. There is little information about the parameters that influence the thermal properties of the materials and their relationship with the microstructure; these are very important, since inadequate selection would cause poor operation or rapid wear of the machine. Information will be collected on the thermal properties of materials in books, scientific journals, software articles, as well as the parameters involved in each of them in materials such as steel, ceramics, plastics, etc. Next, an analysis will be made that relates the different materials that meet the needs of the material needed. In this integration work, information on the thermal properties of the materials was collected: Melting point, Maximum service temperature, Thermal conductivity, Specific heat capacity and Coefficient of thermal expansion in order to analyze their parameters and how heat affects their properties. . Subsequently, 3 examples of materials selection in industry use were selected, taking into account 4 fundamental aspects followed by Dr. Michael Ashby which are: establishing the performance requirements, filtering the materials that meet these characteristics, classification of the materials and document information to select the best material to fit the job.
