Specifika přípravy vybraných paměťových slitin legovaných Zr, Hf a Nb

Abstract

The main aim of this work was to prepare ternary alloys based on Ni-Ti alloyed with Zr, Hf and Nb and to evaluate them in terms of microstructural phases and impurities. For this purpose, optical microscopy, SEM, EDX analysis was used. The theoretical part deals with memory alloys, memory effect, influence of selected alloying elements and impurities, preparation of alloys themselves and some possible applications. The experimental part evaluates the alloys produced by the plasma melting technique and subsequent vacuum induction melting.
