Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

A Novel Differential High-Frequency Current Transformer Sensor for Series Arc Fault Detection

open access: yesSensors, 2019
Fault arc detection is an important technology to ensure the safe operation of electrical equipment and prevent electrical fires. The high-frequency noise of the arc current is one of the typical arc characteristics of almost all loads.

Symplectification of Circular Arcs and Arc Splines

open access: yesCoRR
In this article, circular arcs are considered both individually and as elements of a piecewise circular curve. The endpoint parameterization proves to be quite advantageous here. The perspective of symplectic geometry provides new vectorial relationships for the circular arc.

Complete arcs

open access: yesDiscrete Mathematics, 1997
This is a very useful survey (without many proofs) on what is known about the maximum size \(m(r,q)\) of an \(n\)-arc in \(\text{PG}(r,q)\) and the size \(m'(r,q)\) of the second largest complete arc in \(\text{PG}(r,q)\). The connection of \(n\)-arcs in the projective space \(\text{PG}(r,q)\) (that is, a set of \(n\) points no \(r+1\) of which are ...

Symmetries of arcs

open access: yesJournal of Combinatorial Theory, Series A, 1994
The authors' introduction: ``We denote by \(P \Gamma L(3,q)\) the full collineation group of \(PG(2,q)\) while \(PGL (3,q)\) denotes the group of homographies of \(PG (2,q)\). The stabiliser of a \(k\)-arc \({\mathcal K}\) in \(P \Gamma L(3,q)\) is called the collineation stabiliser of \({\mathcal K}\), while the stabiliser of \({\mathcal K}\) in \(PGL

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...
