Finite Size-Effects in Martensite Microstructure of Magnetic Shape Memory Films. [PDF]
SmallMagnetic shape memory alloys are a promising multifunctional material system for integration into microsystems. Their multifunctionality arises from the coexistence of ferroelasticity and ferromagnetism. While size‐effects in ferromagnetic microstructure are well understood, corresponding experiments on the ferroelastic microstructure are sparse.

Deformation mechanisms in a TiNi shape memory alloy during cyclic loading [PDF]
, 2012 The deformation mechanisms governing the cyclic stress-strain behaviour of a TiNi shape memory alloy were investigated in this work. To understand the development of these mechanisms during cyclic loading, three low-cycle fatigue tests were performed and

The role of the austenite grain size in the martensitic transformation in low carbon steels
Materials & Design, 2019 There is sufficient experimental evidence to propose that the formation kinetics of athermal martensite directly depends on the austenite grain structure from which the martensite forms. Yet, this dependence is frequently ignored.
