Coherent phonon dynamics at the martensitic phase transition of Ni_2MnGa
We use time-resolved optical reflectivity to study the laser stimulated dynamics in the magnetic shape memory alloy Ni_2MnGa. We observe two coherent optical phonons, at 1.2 THz in the martensite phase and at 0.7 THz in the pre-martensite phase, which we

Fine size inclusion can serve as the effective nucleation site to induce the formation of optimal microstructure, i.e. intragranular acicular ferrite (IAF). Here, the low‐alloy steels with different amounts of Ti and Al contents are prepared, and the inclusion characteristics are quantitatively investigated.

Martensite crystallography and chemistry in dual phase and fully martensitic steels
Lath martensite is important in industry because it is the key strengthening component in many advanced high strength steels. The study of crystallography and chemistry of lath martensite is extensive in the literature, however, mostly based on fully martensitic steels.

Plastic deformation behaviour of single-crystalline martensite of Ti-Nb shape memory alloy
β-Ti alloys have attracted considerable attention as new biomedical shape memory alloys. Given the critical importance of the plastic deformation in the martensite phase for the shape memory effect and superelasticity, we investigated here the plastic ...

On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Impact of ε-martensite on the fracture resistance of high-Mn steels1
The formation of ε-martensite is generally considered as detrimental to cracking resistance. The essential work of fracture (EWF) of high-Mn steels with ε-martensite has been determined in the near plane-stress regime.

Dynamic Scenarios of the Formation of Martensite with the {110} Habits in the Ni50Mn50 Alloy [PDF]
Martensitic transformation B2–L10 in the ordered alloy Ni50Mn50, which occurs at comparatively high temperatures (980–920 K), is discussed with the use of dynamic concepts of the wave control of the threshold deformation.

Processing by Equal-Channel Angular Pressing (ECAP) is generally considered superior to most other SPD techniques because it uses relatively large bulk samples.

In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can
