Characterization of Nitinol Produced by Laser Powder Bed Fusion for Mechanical Metamaterial Applications

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Shear-induced α → γ transformation in nanoscale Fe-C composite [PDF]

, 2006
High-resolution transmission electron microscopy and three-dimensional atom probe observations show clearly that a reverse transformation of body-centred cubic ferrite to face-centred cubic austenite occurs during severe plastic deformation of a ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Synergism between coherent precipitation strengthening and FCC-HCP type transformation-induced plasticity

Materials & Design, 2022
It is becoming a trend that many strengthening methods are applied at the same time to overcome the strength-ductility trade-off. However, the combination of precipitation strengthening and transformation-induced plasticity (TRIP) is rarely used ...

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

Advanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Transformation characteristics of γ→ε-M and ε-M→α'-M in high manganese steel under high speed compression

Cailiao gongcheng, 2021
The volume fractions of γ (austenite), ε-M (hcp martensite) and α'-M (bcc martensite) in static and high speed compressed high manganese transformation induced plasticity (TRIP) steel were calculated by the XRD technique to investigate the effect of ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

The evolution of microstructure, martensitic transformation and mechanical properties in Ti–V–Al-based shape memory alloys with changing annealing temperatures

Journal of Materials Research and Technology, 2022
In the present study, the effects of annealing temperature on the microstructure, martensitic transformation and mechanical properties of Ti–V–Al-Gd shape memory alloys were investigated. The results revealed that the phase constituents were dependent on

Crystallography and ageing effect associated with thermoelastic martensitic transformations [PDF]

, 1996
Martensitic transformation means the first-order diffusionless phase transformation in solids. Originally, a particular microstructure observed in quenched steels was called "martensite", in recognition of the well-known German metallurgist A.
