Dersin Amacı

In addition to the properties of materials in low and room temperature properties, it is necessary to know materials`s high temperature behaviours, especially when they are used in high temperature environments. Therefore this course aims to provide students with the high temperature properties and behavior of materials at postgraduate level. 

Dersin İçeriği

Creep, creep activation energy, factors affecting resistance of creep, creep deformation mechanisms, deformation mechanism maps, prediction of long-time creep properties, dynamic recovery and dynamic recrystallication, thermo mechanic processes, fatigue and torsion tests at elevated temperature, creep-fatigue interaction, superplasticity, mechanisms of superplastic deformation, properties of ceramics at elevated temperature, selection of creep-resistant materials.
