Learning activities and teaching methods
Lecture, Practicum
  • Preparation for comprehensive test (10-40) - 20 hours per semester
  • Preparation for an examination (30-60) - 50 hours per semester
  • Preparation for laboratory testing; outcome analysis (1-8) - 8 hours per semester
  • Contact hours - 26 hours per semester
  • Practical training (number of hours) - 26 hours per semester
prerequisite
professional knowledge
Students should have a basic knowledge of chemistry (high school level) and basic knowledge of engineering, technology and properties od material.
learning outcomes
The subject will provide students with profound knowledge of basic properties of metallic materials and their end-use and application potential. Students will build on the whole spectrum of experience and information gained throughout the previous study to be able to assess the behaviour of materials and predict their properties.
