Giant van Hove Density of States Singularities and Anomalies of Electron and Magnetic Properties in Cubic Lattices [PDF]
Physics of Metals and Metallography, v. 120, p. 1282-1290 (2019), 2021 Densities of states for simple (sc) and base-centered (bcc) cubic lattices with account of nearest and next-nearest neighbour hopping integrals $t$ and $t'$ are investigated in detail. It is shown that at values of $\tau \equiv t'/t = \tau_\ast$, corresponding to the change of isoenergetic surface topology, the formation of van Hove $\bf k$ lines takes

Notch aspects of RSP steel microstructure
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012 For a rather long time, basic research projects have been focused on examinations of mechanical properties for Rapid Solidification Powder (RSP) steels. These state-of-art steels are commonly known as “powdered steels“.

Half-Metallic Ferromagnets and Spin Gapless Semiconductors [PDF]
Phys. Met. Metallogr., Vol. 119, No. 13, pp. 1321-1324 (2018), 2019 A brief review of experimental and theoretical studies of half-metallic ferromagnets (HMF) and spin gapless semiconductors (SGS) is given. The data on resistivity and magnetoresistivity are presented. An important role of non-quasiparticle states owing to electron-magnon scattering in transport properties is discussed.

Failure analysis of a hydraulic press clamp
Revista Facultad de Ingeniería Universidad de Antioquia, 2014 This paper describes the analysis and investigation of the causes of the failure of an hydraulic press jaw face grip. Analysis of the fractured surfaces indicated the creation of cracks due to stress concentrators as a result of defective design. On the
