Match the following materials processing concepts with their descriptions:

Synthesis and processing = The stage where raw materials are transformed into engineered materials Engineered materials = Materials created through specific processing techniques Product design, manufacture, and assembly = The final stages where products are created from engineered materials Recycle/reuse = The process of reusing materials, reducing waste Waste = Unusable byproducts from the materials processing chain Signup and view all the answers

Study Notes

Electromagnetic Radiation

Common types include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Tensile Stress

Defined as force divided by initial surface area (σ = F/A₀).

Compressive Stress

Opposite of tensile stress; pushing instead of pulling on a material.

Shear Stress

Force applied perpendicular to the surface.

Torsional Stress

Stress causing twisting or deformation.

Processing-Structure-Properties-Performance

Performance goals lead to increased strength in metallic materials.

State Changes

Freezing: Liquid to solid
Melting: Solid to liquid
Condensation: Gas to liquid
Vaporization: Liquid to gas
Deposition: Gas to solid

Materials Cycle

Raw materials are synthesized and processed into engineered materials.
Products are designed, manufactured, and assembled.
Waste is recycled or reused.
Applications include agriculture, construction, and environmental protection, with considerations for defense, information, energy, and health.
