Contributed by: Christie
  • 1. Material characterization is a crucial aspect of materials science and engineering that involves understanding and evaluating the properties and behaviors of materials. This process typically includes analyzing the structure, composition, and performance of a material to determine its suitability for a particular application or to assess its quality. Various techniques and methods, such as microscopy, spectroscopy, and mechanical testing, are commonly used in material characterization to obtain detailed insights into the material's properties at different scales. By thoroughly investigating and characterizing materials, scientists and engineers can make informed decisions about material selection, design, processing, and optimization, ultimately leading to the development of innovative and high-performance materials for a wide range of industries and applications.
