Results in Physics, 2023 In this paper, a new concept of “dynamic softening” is proposed to explain the mechanism of residual stress reduction through “cold” treatment. The impact of grain size, grain boundary width, and grain orientation on the reduction was studied through ...

Advanced Engineering Materials, EarlyView.Ca2.5Ag0.3Sm0.2Co4O9 semiconductor materials are synthesized and produced in this study using the sol–gel and cold pressing techniques for thermoelectric generator applications. As template samples are added, the Seebeck coefficient and power factor values rise, peaking at 800 °C for Ca2.5Ag0.3Sm0.2Co4O9 at 274.47 μV K−1 and 0.58 mW mK−2, respectively.

AIP Advances, 2018 In this study, we simulated the effects of the anisotropy field (Hk) dispersion of the grains (the main phases and the deterioration layers) for a NdFeB magnetic powder on Hc and squareness ratio in consideration of the magnetic properties of the grain ...

Advanced Engineering Materials, EarlyView.The utilization of direct energy deposition (DED)‐arc additive manufacturing processes in industrial applications is increasing, and these processes have the potential for multi‐material applications. This work provides a overview of the state of research in DED‐arc made functional graded structures, to establish a link to potential industrial ...

Advanced Engineering Materials, EarlyView.High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...

Forming incoherent twin boundaries: a new way for nanograin growth under cyclic loading
Materials Research Letters, 2017 Obvious grain growth was observed in regions around the fatigue cracks in the Au thin films under cyclic loading. Dominant generation of twin boundaries (TBs) and low-angle grain boundaries was observed in the coarsened grains.

Advanced Engineering Materials, EarlyView.The fused filament‐fabricated MAR‐M247 alloy without hot isostatic pressing shows the lowest porosity of 4%. Heat treatment at 1220 °C produces coarse precipitates and carbides. Specimens heat‐treated at 1220 °C exhibit higher tensile strength (683 MPa) and elongation (10%) at room temperature.

Advanced Engineering Materials, EarlyView.This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.
