How does the grain size affect the strength of a material?
How does the grain size affect the strength of a material? In this article we are going to focus on how the grain size impacts on yield strength. What is a grain? A crystal can be modelled as a unit lattice in which atoms are arranged in a specific position, when a group of crystals […]
Material deformation techniques
Material deformation techniques This article discusses various methods where materials are forcibly deformed, and their physical or microstructural properties are altered. This is done to enhance certain mechanical or electrical properties. The deformation usually takes place at high or low temperatures, and this is reflected in the naming of the process. Cold Working This process […]
