Selecting an engineering material is like choosing a dress for a particular occasion. What works for a retro party would surely not work for a formal dinner.
Depending upon the type of equipment or machine, we use different types of materials. We need to pay so much attention to material selection because it is one of the foremost functions of effective engineering design. It determines the reliability of the design in terms of industrial and economical aspects.
For example, a machine that has to be used underwater would require a material that can long endure corrosion effects. Various factors like working conditions, environmental exposure, and operational temperature have a huge impact on the life and efficiency of a machine or equipment, and if materials are not chosen considering these factors at the time of manufacturing, it might have serious implications.
The following is a carefully chosen collection of articles that will help you gain new knowledge (or refresh yourself) about engineering materials and processes.
History of Materials Engineering
Even in the primitive age human beings were civilized and knew how to use different materials in their construction and simple tools. Today we apply terms like Stone Age, Bronze Age, and Iron Age to indicate how competent early man was in dealing with different types of materials. Even the modern science of metallurgy originally evolved from primitive methods of mining.
What to Consider When Selecting a Material for a Particular Design
Material selection can make the difference in whether a great design can lead to a profitable product. Other factors to be considered are the mechanical properties of a material, its resistance to corrosion, and cost effectiveness.
Testing of Metals Used in Mechanical Engineering Components
Material testing is an important aspect of material engineering and manufacturing processes. Unless a material is tested for stress, strain, ductility, permeability, and other factors, it cannot be deemed fit for use. This article provides detailed information about the various types of tests and testing equipment, as well as how to assess the mechanical properties to confirm a material’s suitability for the fabrication of a component.
Understanding the Mechanical Properties of Engineering Materials
Ultimate tensile strength, ductility, necking, fracture, impact strength, and metal fatigue are some of the mechanical properties involved in material selection. These properties are related to each other and help in designing efficient and long lasting mechanical equipment.
