| Summary |
|---|
| In the introduction given subject is focused on basic heat treatment (HT) types, on which selected, the most perspective HT ways follow-up, including their analyses and/or physical metallurgical principles. Further, structures stability and instability conditions are discussed, which occur in case of up-to-day types of surface treatment of metal materials, e.g. after electo heating, plasma or laser exposition. Heat treatments of chosen nonferrous metals are integral part of subject. Up-to-day HT technologies enable to reach promising mechanical-metallurgical steels properties under economical advantageous conditions and favourable energy demands. |
| Learning Outcomes of the Course Unit |
|---|
- student will be able to compare the basic heat treatment (HT) types with unconventional HT types and will be able to use those in technical praxis.
- in some cases student will be able to use the acquired information for the „on line“ HT without conventional followed-up HT
- student will be able to suggest concrete steps for the HT using unconventional technics as are e.g. laser or plasma exposition, electric heat and/or ADI method |
