Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the fundamental mechanism?Plastic deformation in crystalline materials via displacement along crystallographic planes and directions
2. What is the driving force?Movement of dislocations on close-packed planes
3. What is slip in metals?Slip is when layers inside a metal slide past each other, letting the metal bend instead of break. It happens along special planes and directions in the crystal.
4. Why do metals bend instead of break?Because tiny defects called dislocations move through the crystal, letting atomic layers slide. This lowers the energy needed for the metal to change shape.

Crystallographic Planes: Specific, ordered atomic surfaces within a crystal lattice.
Dislocations: Linear crystallographic defects whose motion is responsible for slip.
Burgers Vector (b): A vector defining the magnitude and direction of lattice distortion caused by a dislocation.
Critical Resolved Shear Stress: The minimum shear stress required to initiate dislocation motion and slip.
