Phase stability and magnetic-field-induced martensitic transformation in Mn-rich NiMnSn alloys

AIP Advances, 2012
A series of Ni50-xMn41+xSn9 (x = 0–19) alloys from Ni-rich to Mn-rich composition were prepared, and the composition dependence of phase transitions and magnetic properties were investigated. No γ-phase can be observed until x = 17.

Vacancy-tuned paramagnetic/ferromagnetic martensitic transformation in Mn-poor Mn_{1-x}CoGe alloys

, 2010
It is shown that a temperature window between the Curie temperatures of martensite and austenite phases around the room temperature can be obtained by a vacancy-tuning strategy in Mn-poor Mn1-xCoGe alloys (0

Finite Size‐Effects in Martensite Microstructure of Magnetic Shape Memory Films

Small, EarlyView.
Magnetic 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.

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
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.

Influence of β-Stabilizing Nb on Phase Stability and Phase Transformation in Ti-Zr Shape Memory Alloys: From the Viewpoint of the First-Principles Calculation

Metals
In the present study, the effect of the Nb element on the lattice parameters, phase stability and martensitic transformation behaviors of Ti-Zr-based shape memory alloys was extensively investigated using the first-principles calculation.

The Peculiarities of Martensite Morphology in Nano- and Inhomogeneous Spaces [PDF]

, 2013
The article describes certain experimental situations, in which the small volumes available for the phase transformation can dramatically affect the morphology, substructure of martensite, martensitic transformation itself.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
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

All-d-metal equiatomic quaternary Heusler hypothetical alloys ZnCdTMn (T = Fe, Ru, Os, Rh, Ir, Ni, Pd, Pt): A first-principle investigation of electronic structures, magnetism, and possible martensitic transformations

Results in Physics, 2018
A new series of Zinc-based all-d-metal equiatomic quaternary Heusler hypothetical alloys ZnCdTMn (T = Fe, Ru, Os, Rh, Ir, Ni, Pd, Pt) were designed, and their ground state, electronic structures, magnetism, and possible martensitic transformations, as ...
