This Laboratory Works Guide has been prepared specifically for the use in the Materials Engineering course taught at Kaunas University of Technology and is intended to be used by students of Production Engineering, Aviation Engineering, Nuclear Energy, Thermal Energy and Technology, Mechatronics and Vehicle Engineering first tier (Bachelor) study programs. This Laboratory Guide may be used as a valuable resource when conducting laboratory works and answering theoretical questions during the laboratory work defense. All the works are described uniformly: at the beginning of each work, the Tasks are presented, the Theoretical Part and the Content of the Work follow the first part. At the end of each work, Review Questions and the Content of the Final Report are listed.
