First-principles modeling of temperature and concentration dependent solubility in the phase separating Fe$_x$Cu$_{1-x}$ alloy system

, 2012
We present a novel cluster-expansion (CE) approach for the first-principles modeling of temperature and concentration dependent alloy properties. While the standard CE method includes temperature effects only via the configurational entropy in Monte ...

Impact of Textile Architecture on the Electromechanical Behavior of Conductive Carbon: Silicone Composite Strain Sensors

Advanced Engineering Materials, EarlyView.
A stretchable carbon composite is integrated by stencil printing onto two different types of textile, with different yarn morphologies. The impact of the knit structure and coating direction on the performance of the sensor composite is evaluated and used to derive a model estimating nominal resistance at a given strain near the percolation threshold ...

Thermal stability of Al-Cu-Fe icosahedral alloys

Journal de Physique I, 1991
A stable ideally quasiperiodic phase exists in a small range of concentration, close to the composition Al62Cu25.5Fe12.5. Reducing the iron content, or replacing small amounts of copper by aluminium, lead to icosahedral alloys which exhibit around 650 ○C structural transformations of unclear nature: in the X-ray powder diffraction pattern, the peak ...

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Mechanical properties and microstructural change in (Cu–Fe) immiscible metal matrix composite: Effect of Mg on secondary phase separation

Journal of Materials Research and Technology, 2020
Phase morphology and the distribution of the strengthening phase generally have a strong influence on the movement of dislocations. The presence of minor alloying element Mg in Cu–30Fe alloy significantly affects both the morphology and distribution of ...

Efficient Process Development for Laser Powder Bed Fusion of a Soft‐Magnetic Metallic Glass Composite

Advanced Engineering Materials, EarlyView.
Iron‐based metallic glass alloys exhibit excellent soft‐magnetic properties, and unprecedented geometrical freedom in the design of soft‐magnetic metallic glass components is made possible by additive manufacturing. An efficient workflow for developing parameters for laser‐based powder bed fusion of a Fe‐based metallic glass alloy is presented along ...

Absence of long-range chemical ordering in equimolar FeCoCrNi [PDF]

, 2012
Equimolar FeCoCrNi alloys have been the topic of recent research as "high-entropy alloys," where the name is derived from the high configurational entropy of mixing for a random solid solution.

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Effect of Cr addition on the hot deformation behavior and microstructure evolution of Cu-0.8Fe-0.2Mg alloy

Journal of Materials Research and Technology
The Cu-0.8Fe-0.2Mg and Cu-0.8Fe-0.2Mg-0.2Cr alloys were investigated using hot compression experiments at 600–950 °C and 0.003–10 s−1 strain rates. The effects of Cr addition on the microstructure and recrystallized behavior of the Cu-0.8Fe-0.2Mg alloy ...
