✦ Synopsis

An improvement of the mechanical properties of powder metallurgically produced NiTi shape memory alloys was attained by reducing the impurity contents of oxygen and carbon. Elongation at fracture was increased to 16.5 % for Hot Isostatically Pressed (HIP), as well as for net‐shape samples produced by Metal Injection Moulding (MIM) with plastic deformation before fracture. Furthermore, an enlargement of the utilisable strain of the shape memory effect itself was detected.

## Abstract Pseudoelastic NiTi‐ shape memory alloys (SMAs) provide a high damping capacity and can be used in order to achieve a reduction of peak loads being caused by unexpected shock loading. These “pseudoelastic” properties are related to the formation of martensite M from austenite A, which ha

## Abstract This paper takes into account the localized deformation behaviour of a pseudoelastic NiTi shape memory alloy with finite element method. A three‐dimensional micromechanical model has been developed, in which the difference between the elastic properties of austenite and martensite is co
