Microstructural Evolution and Mechanical Performance of Plasma‐Assisted Hybrid Friction Stir Welded Dissimilar Aluminum–Copper Joints

open access: yesAdvanced Engineering Materials, EarlyView.
Plasma‐assisted hybrid friction stir welding of dissimilar AlCu joints employs localized plasma preheating to balance heat input and enhance plastic flow. The optimized process reduces axial force by up to 35%, refines the microstructure, and achieves ≈96% joint efficiency.

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

Snaking states on a cylindrical surface in a perpendicular magnetic field

open access: yes, 2013
We calculate electronic states on a closed cylindrical surface as a model of a core-shell nanowire. The length of the cylinder can be infinite or finite.

Flow over rough-walled circular cylinder in the critical area [PDF]

open access: yes, 2018
The article deals with the flow over a roughwalled circular cylinder in the critical area at high Re numbers. The subject of the paper is a comparison of the standard calculation of the aerodynamic drag coefficient with numerical modeling.

Mechanically Deposited Wear‐Resistant Amorphous Zr55Cu30Al10Ni5 Coatings

open access: yesAdvanced Engineering Materials, EarlyView.
Mechanically deposited from glassy ribbons, the Zr55Cu30Al10Ni5 amorphous coating formed a hard, continuous layer on AISI 1010 steel, tripling substrate hardness, lowering friction, and reducing wear. Despite its rough surface, it showed friction and wear behavior comparable to the crystalline alloy, highlighting its strong potential as a durable ...

GRAPHICAL AND ANALYTICAL APPROACH ON CYLINDRICAL – CONICAL INTERSECTIONS

open access: yesJournal of Industrial Design and Engineering Graphics, 2019
The cylindrical – conical intersections are often met in technique as parts of pipes, tanks, bends etc. The paper work proposes a comparison between methods to solve the cylindrical – conical intersection problems.

Integral representations for products of two parabolic cylinder functions with different arguments and orders

open access: yes, 2015
This paper derives new integral representations for products of two parabolic cylinder functions. In particular, expressions are obtained for D_{nu}(x)D_{mu}(y), with x>0 and y>0, that allow for different orders and arguments in the two parabolic ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Cylinders on surfaces

open access: yesCommentarii Mathematici Helvetici, 1978
(Note that when ~ = 1 the two inequalities coincide.) The proof will consist of two parts: (i) we show the validity in the universal covering of M, /~7/, of the construction given in Figure 3 in [2] (without the symmetry about the vertical geodesic) and then show, as in [2], that the top lateral geodesic in Figure 3 can intersect at most one of the ...
