Creep and Inspection Techniques in Materials Science

Flashcards focused on key vocabulary and concepts related to creep and inspection techniques in materials science.

Creep

Time-dependent plastic deformation of materials under constant static stress.

Creep Conditions

The conditions under which creep occurs, involving constant load and high temperatures.

Melting Point (Tm)

The temperature at which an alloy starts to melt; key in determining creep behavior.

Dislocation Movement

The motion of dislocations in the crystal structure, which is significant during creep.

Larsson Miller Parameter

A parameter used in assessing creep rupture life based on temperature and time.

Face-Centred Cubic (FCC) Structures

Crystal structures characterized by lower diffusion rates affecting dislocation movement.

Non-Destructive Testing

Methods used to find defects in materials without causing damage.

Dye Penetrant Testing

A method to detect surface discontinuities using visible dyes.

Ultrasonic Testing

A non-destructive testing method that uses sound waves to detect defects.

Aerosol Sprays in Testing

Portable application of dye penetrants which simplifies inspection processes.

Acoustic Emission Testing

A method that detects transient elastic waves produced by the rapid release of energy in materials.
