[Translate to English:] — Fig. 1 a) Stress–strain and b) stress-temperature behavior of the Fe-SMA material; c) application of SMA for the reinforcement of an existing component under cyclic loading

We’re happy to share that our latest review article has been published in Shape Memory and Superelasticity: “Iron-based Shape Memory Alloys in Construction: A Review of Research, Applications, and Challenges.”

This paper explores how Fe-SMAs are transforming civil engineering with their unique ability to induce and recover prestress, making them ideal for retrofitting, strengthening, and fatigue repair of infrastructure.

Key highlights:

Proven use in concrete, steel, composite, and glass structures
Simple, versatile installation methods (e.g., bonding, clamping, bolting)
Advantages over traditional reinforcements in adaptability
Outlook on durability, corrosion resistance, and future research needs

We thank Prof. Thomas Niendorf for the kind invitation to contribute to this Special Issue honoring Prof. Hans Jürgen Maier.
