Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Gongye shui chuli针对工业废水中六价铬〔Cr（Ⅵ）〕高毒性且难以高效去除的问题，本研究成功制备了一种负载硫化亚铁的磷酸改性生物炭复合材料（FeS-PBC），并系统考察其对Cr（Ⅵ）的去除性能及作用机制。结果表明，在600 °C、40% H3PO4浓度、热解时间2 h，FeS与PBC的质量比为2∶1时，FeS-PBC表现出最佳的Cr（Ⅵ）去除性能：在初始Cr（Ⅵ）质量浓度为100 mg/L、pH=4.5、温度为25 °C条件下，去除率达87.3%，为未改性生物炭的5.5倍；当温度升至35 °C时，最大吸附容量可达123 ...

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.
