Materials processing is the set of techniques used to transform raw materials into finished or semi-finished products with defined shapes, microstructures, and properties. It encompasses material selection, synthesis or refinement, forming and shaping, consolidation, finishing, and testing. The field covers metals, polymers, ceramics, composites, and emerging materials such as semiconductors and bio-based materials. The goal is to develop components that meet performance requirements while optimizing cost, manufacturability, and reliability.

Common processing methods include casting and solidification, deformation processing (rolling, forging, extrusion, and drawing), powder processing and sintering, and additive manufacturing. Finishing operations such as heat treatment, surface engineering, coating, machining, and joining complete the production chain. Each method influences the material's microstructure and properties, through mechanisms like grain refinement, phase transformation, and defect control. Process-structure-property relationships guide design choices and quality control.

Equipment ranges from furnaces, kilns, and heat-treatment ovens to mills, presses, reactors, extruders, and additive manufacturing systems. Process control relies on sensors, modeling, and statistical methods to achieve consistent properties. Quality assurance uses standard tests and nondestructive evaluation to verify conformance to specifications.

Current trends in materials processing emphasize sustainability and energy efficiency, recycling and circular economy considerations, and the integration of computational materials science, data analytics, and multi-scale modeling to accelerate development. Additive manufacturing and hybrid processing enable complex geometries and new material architectures, while continued research addresses scale-up, defect management, and cost reduction.
