Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

<p>Preserving the shape memory effect (SME) and superelasticity (SE) in shape memory alloys (SMAs) after a joining process is of great importance. In this work Ni-rich NiTi SMAs were laser welded using a Nd:YAG laser in continuous mode. A detailed structural characterization was carried by means of X-ray diffraction (XRD). It was possible to observe the existence of a microstructural gradient from the base material (BM), which contained only austenite, through the heat affected zone (HAZ) and the fusion zone (FZ), where both zones contained austenite and martensite. The mechanical behavior under cyclic load/unload of the welded samples may be explained taking in consideration the structural information retrieved from the XRD analysis.</p>
