“…The second group includes metals with a ratio lower than 1.633 as Zr (1.589) and Ti (1.587), with a AE 20-408 tilted texture from the normal direction toward the transverse direction. [55] The third group includes materials with about equal ratio than the ideal value of 1.633, such as Mg, and that tend to form basal fiber textures during rolling. From the literature, [56,57] it was found that e-martensite can be included in the second group, together with Zr and Ti.…”

High Mn steels, alloyed with Si and Al, present large plasticity when deformed due to the TRIP/TWIP effect. The present work studies the microstructural evolution and its influence on the mechanical behavior of a steel containing 17%Mn and 0.06%C after cold rolling to 45 and 90% reduction and subsequent annealing at 700 °C for different times. The microstructural analysis is performed by X‐ray diffraction (XRD), scanning electron microscopy (SEM)‐electron backscatter diffraction (EBSD), and transmission electron microscopy (TEM). It is observed that cold reduction induces the formation of ϵ‐ and α′‐martensite. The material exhibits yield and tensile strength around 700 and 950 MPa, respectively, with a total elongation around 43% and a work hardening exponent of around 0.30 after 45% cold rolling and subsequent annealing and a yield and tensile strength of 750 and 950 MPa, respectively, with a total elongation of almost 50% when 90% cold rolling and subsequent annealing. The austenite texture contains brass, copper, and Goss components, while the α′‐ and ϵ‐martensite textures mainly consist of rotated cube and prismatic and pyramidal fibers, respectively.

“…For continuous distillation applications especially the so‐called rotating zigzag beds (RZBs), mainly developed by Wang et al , , have shown superior performance compared to known single‐block packings in RPB and have resulted in a number of industrial applications, primarily in Asia , . Unlike classical RPBs with so‐called single‐block packings , which are fixed in between two simultaneously rotating disks, the RZB rotor consists of a rotating disk and a stationary disk, on which two series of circular baffles are mounted in an alternating fashion.…”

The growing demand for flexible and compact separation technologies has promoted the application of high‐gravity technology, like rotating packed beds (RPBs). Mass transfer characterization and packing design play an important role in the development of this technology. This article provides a systematic approach towards the evaluation of packing and the development of advanced packing design for distillation in RPBs. For the latter, an additive manufacturing approach is used to develop a new Zickzack packing for RPBs. The new packing provides better mass transfer at reduced pressure drop compared to available conventional packings, while being competitive in terms of mass transfer with the industrially applied rotating zigzag bed at significantly reduced pressure drop.

“…Generally, the as-extruded Mg alloys exhibit intensive fiber texture with basal planes paralleled to extrusion direction. [45] The deformation mechanisms largely relies on the orientation of the applied stress and texture due to the low symmetry of Mg alloys. The basal slip with lowest critical resolved shear stress (CRSS) was inhibited when the tensile direction paralleled to extrusion direction.…”

The microstructure with weak fiber texture and dense precipitates is designed and produced through extrusion and subsequent ageing treatment of Mg-6Zn-0.2Ce (wt%) alloy. Results show that ageing treatment improves the strength of the as-extruded Mg-6Zn-0.2Ce (wt%) alloy and retains the ductility. The peak-aged alloy exhibits a good combination of strength and ductility, which is superior to the commercial Mg alloy. The yield strength and elongation to fracture of the peak-aged Mg-6Zn-0.2Ce (wt%) alloy are 225 MPa and 32.1%, respectively. The strength improvement of the peak-aged alloy is attributed to dense rod-like precipitates, and the superior ductility is mainly due to weaker texture and homogeneous microstructure.
