Introduction to Materials (Duration approx. 30 min)

​

1. Material Classes
Contents:

• Classification into:

  • Metals (e.g., steel, aluminum)

  • Non-metals (e.g., ceramics, plastics)

  • Composite materials (e.g., CFRP, GFRP)

• Areas of application for each material class

Learning Objective:
Trainees can assign materials to the correct classes and describe basic differences.

​

2. Properties of Materials
Contents:

• Mechanical properties: hardness, strength, elasticity

• Thermal properties: thermal conductivity, expansion

• Chemical properties: corrosion behavior, resistance

• Physical properties: density, electrical conductivity

Learning Objective:
Trainees recognize and evaluate typical material properties with regard to their use in manufacturing.

​

3. Steel and Its Alloys
Contents:

• Basic properties of steel

• Influence of alloying elements such as chromium, nickel, molybdenum

• Difference between unalloyed, low-alloyed, and high-alloyed steel

Learning Objective:
Trainees understand how alloying elements affect the properties of steel and select appropriate materials for specific applications.

​

4. Practical Material Testing
Contents:

• Methods for material identification:

  • Hardness testing (e.g., Brinell, Rockwell)

  • Tensile test to determine strength

  • Magnetic test to distinguish types of steel

  • Charpy impact test

Learning Objective:
Trainees perform basic testing procedures, identify material properties, and use them for material assessment.

Special Benefits of VR Training:

• A typically abstract topic like materials science is conveyed in a practical and interactive way

• Numerical values such as hardness or strength come to life through interactive experiences
