Crystallography

Subject and UNIT: Materials Science: Unit I: Crystallography

Most frequently, the source about which nuclei are formed on solid particles are always present in the melt.

Crystallography

Subject and UNIT: Materials Science: Unit I: Crystallography

The formation of nuclei in a melt without the aid of impurity foreign particles is called homogeneous or self-nucleation.

Crystallography

Subject and UNIT: Materials Science: Unit I: Crystallography

Nucleation is the beginning of phase transformation.

Crystallography

Subject and UNIT: Materials Science: Unit I: Crystallography

Phase transformation is an important process in the production and treatment of metallic compounds and alloys.

Many substances exist in more than one stable crystalline form.

Subject and UNIT: Materials Science: Unit I: Crystallography

The combination of a slip plane and slip direction is known as slip system. as slip system. Slip direction is the most important factor in slip system.

Types: Slip, Twinning

Subject and UNIT: Materials Science: Unit I: Crystallography

Plastic deformation of a single crystal occurs in two ways. They are (a) Slip (b) Twinning

The defects on the surface of material are called surface defects or plane defects. They are also known as two dimensional imperfections.

Types

Subject and UNIT: Materials Science: Unit I: Crystallography

The defects due to dislocation or distortion of atoms along a line are known as line defects. These defects are also called dislocations.
