Introduction to Materials Science and Engineering 1.1

Materials Science

Study of structures and properties of materials.

Materials Engineering

Designing materials for specific properties and uses.

Materials Scientist

Develops new materials through synthesis and research.

Materials Engineer

Creates products using existing materials and techniques.

Functional Perspective

Role distinction between scientists and engineers.

Applications of Materials

Influences transportation, housing, clothing, and food production.

Material Selection

Choosing materials based on cost and performance.

Material Limits

Understanding how properties change with usage.

New Material Creation

Processing in Materials Science

Influences structure, properties, and performance of materials.

Processing Techniques

Methods include casting, forging, rolling, coating, heat treatment.

Material Structure

Arrangement of internal components at various scales.

Subatomic Structure

Electrons and nuclei interactions within atoms.

Atomic Structure

Organization of atoms or molecules relative to each other.

Microscopic Structure

Large groups of atoms observable with a microscope.

Macroscopic Structure

Structural elements visible to the naked eye.
