Materials selection and case studies

Abstract

In the most general sense, everything that people need is called a material. In a specific sense, we can say that all kinds of tools and equipment that engineers use to produce are called materials. Materials Science studies the various properties of materials such as mechanical and physical; It is also a branch of science that deals with their application to various scientific and technological fields and is in the interest of almost every technical staff member. A technical staff member who does not have sufficient knowledge about the structure and properties of the materials cannot choose the most suitable material for his usage area. Errors can reach large dimensions; this can put the choice of the material and other relevant units in a difficult situation. Understanding materials has led to progress in design since ancient times. The process of replacing old materials with new ones has occurred from time to time, as there is so much material today than before. The importance of material selection as part of the design process is growing, especially due to industrial competition. Therefore, design and material engineering and scientists are in close relationship for the design and selection of economical materials that will best respond to the desired service conditions. More than 200 thousand materials used in the industry are used. These materials should be selected in accordance with their usage areas. If the materials are chosen incorrectly, this causes loss of life and property. In this study, diagrams used in material selection are introduced and 3 examples are given on the subject.
