Název v původním jazyce

Effect of zirconium, niobium and chromium on structure and properties of Ni-Ti alloy

Popis výsledku v původním jazyce

This work deals with the possibility of modification of the phase composition and improvement of the properties of the NiTi alloy by alloying with other elements. After the production by conventional melting metallurgy as well as powder metallurgy, the Ni-Ti alloys contain in addition to the NiTi shape memory phase a lot of other phases, for example Ti2Ni, Ni3Ti, Ni4Ti3. Some of these phases can have an undesirable effect on the properties of the Ni- Ti alloy. A possible solution is the addition of alloying elements to destabilize these phases. The aim of this work is to describe the effect of Zr, Nb and Cr as alloying elements in the amount of 1 and 3 wt. % on microstructure, phase composition, hardness and transformation behavior of the Ni-Ti alloy produced by powder metallurgy using reactive sintering. Alloying by chromium leads to increase of hardness and microhardness of the NiTi phase whereas the addition of the alloying elements niobium and zirconium increases the temperatures of phase transformations. © 2018.
