Preparation of nitinol by reactive sintering

Popis výsledku v původním jazyce

Melting metallurgy processes of NiTi shape memory alloys can lead to undesirable contamination of the melt and forming of oxide inclusions. One possible solution of this problem is reactive sintering using pure elemental powders. Reactive sintering method enables to produce high-purity materials. In this process, compressed mixture of metallic powders is transformed to bulk intermetallic phases via thermally activated exothermic reactions. The evolved heat sustains and helps to propagate the reaction front through the body of the reactants. Therefore this process is called ?Self-sustainable High-temperature Synthesis (SHS). This work aims to optimize the parameters of the SHS process for the preparation of NiTi shape memory alloy to obtain a high-purity, low-porosity material.
