L9- Material Processing

Flashcards containing key terms and definitions related to material processing and sustainable practices.

Ferrous Metals

Metals that contain iron and alloys containing iron above a certain level.

Noble Metals

Resistant to corrosion or oxidation, usually precious metals such as platinum, palladium, and rhodium.

Alloy

A material composed of two or more metals, or a metal and a non-metal, which has different properties than its constituent materials.

Plastic Deformation

Permanent deformation of materials that occurs when the stress exceeds the yield strength.

Annealing

A heat treatment process used to relieve internal stresses and improve ductility by reducing defects in the crystal structure.

Casting

A manufacturing process where liquid material is poured into a mold and allowed to solidify.

Dislocation

A defect within a crystal structure that facilitates plastic deformation.

Sintering

A process that compacts and forms solid materials by applying heat without melting.

Plasticity

The ability of a material to undergo significant deformation without breaking.

Work Hardening

The process of increasing a material's strength and hardness through plastic deformation.

Heat Treatment

A group of industrial and metalworking processes used to alter the physical and sometimes chemical properties of a material.

Thermoplastics

Plastics that become moldable above a specific temperature and return to a solid state upon cooling.

Composites

Materials made from two or more constituent materials with significantly different physical or chemical properties.

Grain Boundaries

The interfaces that separate different crystals or grains in a material, which can significantly affect mechanical properties.

Crystalline Defects

Non-perfect structural variations in crystal lattices that can affect the properties of materials.

Hybrid Materials

Materials that combine two or more types of materials to obtain improved properties.

Thermal Conduction

The process of heat transfer through a material without the movement of the material itself.

Microstructure

The structure of a material observed at a microscopic level, which influences its properties.

Mechanical Properties

The properties of a material that reveal its elastic and inelastic behavior when a force is applied.

Surface Treatment

Processes that alter the surface of a material to improve its properties such as wear resistance, aesthetic appearance, or corrosion protection.

Grain Structure Evolution

Changes in the microstructure of a material due to processing such as cold working or heat treatment.
