Basic information
Level of Studies: Undergraduate applied studies
Year of Study: 2
Semester: 3
Requirements:
Goal: The course aims to acquaint students with the basic types of materials used in mechanical engineering, their structure, properties, application and possibilities for processing and altering their chemical, physical and technological properties. This course is designed to provide information about the welding techniques as well as the welding equipment.
Outcome: After completion of the course, the students should be able to: • Identify the type of chemical bonding, crystal structure, and properties for a given type of material (metal, ceramic, polymer). • Differentiate the characteristic stress–deformation in metals, ceramics, crystals and amorphous materials, polymers. • Perform experiments (standard destructive tests) from which they analyze and interpret results of mechanical tests (hardness, plasticity, toughness, material resistance and deformation) on standard devices and machines (devices for measuring hardness by static and dynamic load, tensile testing machines, Charpy pendulum, extensometers, …). • Recognize the types of damage in engineering materials, their application and behaviour in exploitation (fatigue and creep). • Differentiate between steels and irons and define the fields of their application. • Select the proper heat- or chemical treatment, based on the required properties of the steel • Define the characteristics and application of light and non-ferrous metals and alloys (Al, Cu, Ni, Ti, ...). • Distinguish conventional welding procedures. • Understand the conventional welding techniques. • Differentiate between the conventional welding techniques and components of welding equipment. • Identify the influence of welding parameters on the quality of the joint.
