Composition‐Tuned Enhancement of the Anomalous Nernst Effect in FeCo–Pt Thin Films on Rigid and Flexible Substrates

Advanced Engineering Materials, EarlyView.
Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Twin-induced plasticity of an ECAP-processed TWIP steel [PDF]

, 2017
The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult.

Hot Deformation Behavior and Hot Processing Map of 4Cr5MoSiV1 Steel

Material Sciences, 2013
利用Gleeble-1500D热模拟试验机对4Cr5MoSiV1钢在950℃~1100℃，应变速率为0.01~10.0 s−1，最大应变量为50%的条件下进行了热压缩实验。结果表明：真应变–应力曲线在应变速率为10 s−1时出现波动现象；经计算得到4Cr5MoSiV1钢的激活能为416.16 kJ·mol−1，建立该合金的本构方程形式为，经验证与实验结果吻合较好；基于动态材料模型建立的热加工图可分为两个区域，在低应变速率0.01 s−1和0.1 s−1时为加工稳定区，且变形温度为1050℃时，能量耗散功率达到最大值0.3；在高应变速率1 s−1和10 s−1时为加工失稳区。结合变形组织的分析，合金在稳定区下具有较好的热加工性能。 The hot deformation characteristics

Hot deformation behavior of spray formed FGH4095

Acta Physica Sinica, 2012
For the numerical simulation of hot working process of spray-formed FGH4095, the high temperature deformation behavior of spray-formed FGH4095 is studied at different deformation temperatures (1010-1140 ℃) and different strain rates (0.001-10.0 s-1) using Gleeble 3800 thermal simulator. The constitutive equation is established with the sinh model.

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics

Advanced Engineering Materials, EarlyView.
Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

Research progress in hot deformation behavior of high entropy alloys

Cailiao gongcheng
The high entropy alloy overturns the traditional design idea that one or two elements are the main elements, and its design concept of multi-element and high mixing entropy endows it with excellent properties such as high strength, high toughness ...
