Explaining Defects of the Universal Vacua with Black Holes-Hedgehogs and Strings
Autor: C. R. Das, L. V. Laperashvili, H. B. Nielsen, B. G. Sidharth
Publikováno v: Universe, Vol 5, Iss 3, p 78 (2019)
Assuming the Multiple Point Principle (MPP) as a new law of Nature, we considered the existence of the two degenerate vacua of the Universe: (a) the first Electroweak (EW) vacuum at v 1 ≈ 246 GeV—“true vacuum”, and (b) the second Planck scale

Creep Behavior of Inconel-625 and Its Modeling at 843 K
Autor: Sunil Goyal, A.K. Bhaduri, S. C. S. P. Kumar Krovvidi, C. R. Das, J. Christopher, J. Vanaja
Publikováno v: Transactions of the Indian National Academy of Engineering. 7:541-548
Inconel-625 is used for the fabrication of bellows in high-temperature sodium valves operating at 843 K in fast breeder reactors. Creep deformation coupled with the damage is one of the major failure modes of the bellow. The creep data required for t

Study on hot cracking susceptibility of alloy 617M and an analysis on parameters used for its evaluation
Autor: H. C. Dey, Madavan Vasudevan, Shaju K. Albert, C. R. Das, M. Divya
Publikováno v: Journal of Manufacturing Processes. 68:1714-1725
Hot cracking study on nickel base superalloy, alloy 617M, a candidate material for Advanced Ultra Supercritical (AUSC) power plant applications, was carried out. The susceptibility of this alloy to solidification cracking was evaluated using varestra

Influence of Stress Ratio and Contact Pressure on Fretting Fatigue Behavior of Modified 9Cr-1Mo Steel
Autor: V. Shiva, A. Nagesha, N.L. Parthasarathi, Shaju K. Albert, Sunil Goyal, Utpal Borah, A.K. Bhaduri, R. Kannan, C. R. Das
Publikováno v: Journal of Materials Engineering and Performance. 30:2822-2831
Influence of contact pressure and maximum cyclic stress (σmax) on the fretting fatigue behavior of modified 9Cr-1Mo steel has been studied using contact pads made of the same steel. The contact pressure was varied from 50 to 200 MPa using σmax of 4
