These flashcards cover the key concepts and learning outcomes from the BME2100 Materials 1 lecture, helping students prepare for the upcoming exam.

What are the two main sections of the BME2100 course?

Metals/Metal Processing and Polymer Technology.

What percentage of the course grade is the written examination worth?

70%.

What are the classes of materials discussed in the course?

Metals, Polymers, and Ceramics.

Define Materials Science.

Investigating relationships that exist between the structure and properties of materials.

Define Materials Engineering.

Designing the structure of a material to produce predefined properties based on structure-property correlations.

What is the significance of microstructure in material properties?

Microstructure influences the mechanical properties like hardness and toughness.

What are some recommended textbooks for the course?

Materials Science and Engineering by WD Callister and Plastics Engineering by RJ Crawford.

What factors are included in the measurement of mechanical properties of materials?

Elastic constants, yield strengths, fracture strengths, fatigue strengths, and hardness.

What does the Iron-Carbon phase equilibrium diagram describe?

The microstructures of steel and cast iron as functions of composition and temperature.

What are the primary classes of alloy steels discussed in the course?

Copper and aluminium alloys.

Explain the difference between thermoplastics and thermosets.

Thermoplastics can be remelted and reshaped, while thermosets cannot be reprocessed after curing.
