Supernovae Types Ia/II and Intracluster Medium Enrichment [PDF]

, 1997
We re-examine the respective roles played by supernovae (SNe) Types Ia and II in enriching the intracluster medium (ICM) of galaxy clusters, in light of the recent downward shift of the ASCA abundance ratios of alpha-elements to iron favoured by Ishimaru

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Effects of Continuous Rolling and Reversible Rolling on 2.4% Si Non-Oriented Silicon Steel

Crystals
The cold-rolled non-oriented silicon steel sheets with a Si content of 2.4 wt.%, produced by continuous and reversible cold rolling, were used as the experimental material. The effects of annealing temperature on the microstructure, texture, and magnetic

PBF‐LB/M of Ti‐6Al‐4V: High‐Pressure Solution Treatment and Aging for Applications in a Sustainable Aerospace

Advanced Engineering Materials, EarlyView.
Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Evaluation of Adhesion Strength of Coils of a High-Speed Motor Applying Welding-Less Coils

IEEE Access
Motors for electric drive systems applied to electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs) need to be compact and to have high power density to reduce vehicle weight, to expand the living space, and to lower costs. Several means of

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Robust Design Optimization Considering Static Eccentricity Fault of Six-Phase IPMSM

IEEE Access
Static eccentricity fault (SEF) primarily occurs due to external mechanical shocks and incorrect manufacturing processes. In the case of SEF condition, vibration and noise in the electric motor are generated due to unbalanced magnetic forces ...
