Materials Science: A Comprehensive Overview
Materials Science
Introduction
Everything in the universe consists of matter, which occupies space and has mass. This matter presents itself in nature in various forms, each with specific properties. Matter is composed of atoms. The origin of these atoms can be traced back to the Big Bang (Hydrogen, Helium, and Lithium), the cores of stars (Iron), and supernova explosions (heavier atoms).
Classification of Materials
- Raw Materials: Obtained directly from nature (e.g., wood, granite).
- Processed Materials:
