Abstract
The paper presents a series of in-situ SEM-EBSD experiments mainly devoted to Ni-Mn-Ga shape memory alloys and pure Al. Firstly, orientation relationship between austenite and martensite during phase transformation of Ni-Mn-Ga alloys has been investigated by in-situ EBSD measurements. In the next step, the interface between the austenite and twinned martensite was directly visualised and mapped using a temperature gradient. Depending on the distance from the interface, three distinct types of martensite crystal lattices and their transformation path were revealed. As a result, a new concept for adaptive structures is proposed having regard to a sequential form of martensitic transformation. Then employing the heating stage and EBSD, a precise method for the orientation process of Ni-Mn-Ga-based single crystals was demonstrated. In a further step, in-situ experiments dealing with the so-called twin boundary engineering are shown. Depending on the twin configuration (parallel, perpendicular or mixed), different effects can be observed, e.g., magneto-elasticity, magneto-plasticity, and magnetically induced pseudoelasticity. Finally, the re-crystallisation process in pure Al has been studied.
