Features are revealed for the inheritance of bimetallic rolled product of dendrite inhomogeneity of the cast structure of two-phase austenite-ferrite steel applied in the form of a cladding layer on a base of low-alloy steel. It is shown that the banded and fiber structure of a cladding layer on rolled product is the result of retention of chemical liquation and rebuilding of the surfacing dendritic structure. Results are given for quantitative analysis of specimen fractures tested in static tension in the form of two parameters, i.e., work for plastic deformation localization and specific area of a fracture surface characterizing the energy content of failure. Areas of the surface of all fractures having a complex configuration are determined with considerable accuracy due to the original procedure of digital measurement of a three-dimensional failure surface from results of photogrammetric exposure on a meso-macro-scale followed by recreation of a complete three-dimensional model of the relief. Quantitative properties of fractures are supplemented by the strength and ductility indices of bimetallic rolled product, which makes it possible to substantiate the optimum version of final heat treatment and material use taking account of carbon content in the main layer. © 2017 Springer Science+Business Media New York

Creation of a nitrogen atmosphere within a tank gas space with sulfurous oil leads to a reduction in steel corrosion rate and pyrophoric deposit formation rate. A reduction in oxygen content in the gas phase to a level of 3 vol.% or less makes it possible to avoid pyrophoric iron sulfide formation. © 2014 Springer Science+Business Media New York

This paper deals with research into the evacuation of children from pre-school educational institutions. The research was designed to determine possible values for their pre-movement time and to thoroughly investigate the parameters of their movement along the emergency escape routes. All the stages of the research conducted are described including the preparation and arrangements for the actual observation studies and the collection of basic empirical data and their statistical treatment. This includes the analysis of the pre-movement time for pre-school educational institutions, a theoretical analysis for establishing the relationships between speed and density of flows of children of different age groups during their upward and downward movement on stairs, through door openings, along horizontal routes at a normal walking speed, and while running. It also includes the categorization of movement by a degree of emotional state and psychological abilities of those people involved. The use of the results obtained for evacuation planning under various conditions in pre-school educational institutions is also discussed. Copyright © 2012 John Wiley & Sons, Ltd.

The problem of probabilistic prediction of residual operating life of measurement equipment with parametric failures is investigated. A general analytical solution of the problem with an arbitrary finite number of defining parameters is presented. The obtained solution is applied to a practical example. © 2016 Springer Science+Business Media New York
