Materials synthesis and processing involve creating and shaping substances for specific purposes. Synthesis utilizes methods like chemical vapor deposition and alloying to achieve controlled properties. Processing, including techniques like casting and heat treatment, refines materials for functional components. Understanding the structure-property relationship is crucial for tailored performance. Key aspects include nanostructuring, composites, and alloys for unique properties. Additive manufacturing, like 3D printing, revolutionizes processing, offering design flexibility.
