Correlation between Microstructural Evolution and Mechanical Properties of 2000 MPa Cold-Drawn Pearlitic Steel Wires during Galvanizing Simulated Annealing by Xiuyu Lu, Jing Liu, Guifeng Zhou, Lulu Feng, Zhen Wang

“…It was found that the torsional performance of the wires deteriorated after annealing at 450 °C for 2–5 min, and the corresponding microstructural evolution was accompanied by the partial degradation of lamellar pearlites due to the diffusion and dislocation pinning of dissolved carbon atoms in ferrites, and it is not feasible to achieve the matching of strength and torsion laps by prolonging the holding time. …”

Extracellular enzyme activity in the coastal upwelling system off Peru: a mesocosm experiment by K. Spilling, K. Spilling, J. Piiparinen, E. P. Achterberg, J. Arístegui, L. T. Bach, M. T. Camarena-Gómez, E. von der Esch, M. A. Fischer, M. Gómez-Letona, N. Hernández-Hernández, J. Meyer, R. A. Schmitz, U. Riebesell

“…Here, we focus on the pelagic remineralization of organic matter by the extracellular enzyme activity of leucine aminopeptidase (LAP) and alkaline phosphatase activity (APA). After the addition of the OMZ water, dissolved inorganic nitrogen (N) was depleted, but the standing stock of phytoplankton was relatively high, even after N depletion (mostly <span class="inline-formula"><i>&gt;</i></span> 4 <span class="inline-formula">µ</span>g chlorophyll <span class="inline-formula"><i>a</i></span> L<span class="inline-formula">⁻¹</span>). …”

Cladding thick Al plate onto strong steel substrate using a novel process of multilayer-friction stir brazing (ML-FSB) by Guifeng Zhang, Xiaohui Yang, Daheng Zhu, Linjie Zhang

“…Friction stir brazing (FSB) using a pinless tool together with a braze was developed to extend bond area over friction stir lap welding. When using a large pinless tool of Ø40 mm to clad 10 mm thick 5083Al plate to 16Mn steel by FSB with Zn braze, the thermomechanical effect was sufficient to achieve wetting on Al side by dissolving Al into molten Zn, but joint could not be formed due to poor wettability on steel side. …”

Mechanical Performance Evaluation of the Al-Mg-Si-(Cu) Aluminum Alloys after Transient Thermal Shock through an Novel Equivalent Structure Design and Finite Element Modeling by Congchang Xu, Ke Liu, Hong He, Hanlin Xiang, Xinxin Zhang, Luoxing Li

“…By sorting the whole welded joint into multi-material composed structure and introducing the obtained material constitutive relation and damage parameters, tensile properties were precisely predicted for typical types of weld joint such as butt, corner, and lap joints. The results show that precipitate coarsening, phase transformation from β″ phase to Q′ phase, and dissolving in the temperature range of 243.3–466.3 °C during the thermal shock induced a serious deterioration of the mechanical properties. …”
