Crystalline Structures Flashcard

Front

Crystalline Structure

Back

A material structure where atoms are arranged in a regular, repeating pattern.

Front

Which property is influenced by the Crystalline Structure of a material?

Back

Strength

Front

In a Face-Centered Cubic (FCC) Structure, where are the atoms positioned?

Back

At the corners and the center of each face of a cube.

Front

Characteristic of a Face-Centered Cubic (FCC) Structure?

Back

High ductility

Front

Does Titanium alloys have a Face-Centered Cubic (FCC) or Body Centered Cubic Cell (BCC) structure?

Back

Face-Centered Cubic (FCC)

Front

Main characteristic of a Body-Centered Cubic (BCC) Structure?

Back

Less densely packed than FCC structures; atoms are located at each cube corner and one in the cube center.

Front

Why is a Body-Centered Cubic (BCC) crystal structure important in biomedical surgical instruments?

Back

BCC steels have high hardness and strength, providing durability and resistance to wear during repeated sterilisation and use.

Front

How are atoms arranged in a Hexagonal Close-Packed (HCP) Structure?

Back

Atoms are arranged in a hexagonal pattern with each atom surrounded by 12 nearest neighbours, creating a high packing efficiency.

Front

Characteristic of a Hexagonal Close-Packed (HCP) Structure?

Back

High strength and stiffness along specific crystallographic directions due to its atomic arrangement.

Front

Amorphous material

Back

A material with no long-range ordered atomic arrangement.

Lacks a regular atomic arrangement
