Free Download Aspects of Modelling: Track Layouts By Anthony New
2011 | 88 Pages | ISBN: 0711033552 | PDF | 45 MB
This valuable new addition to the highly successful ‘Aspects of Modelling’ series will give modellers of all abilities the necessary skills to perfect the most important aspect of their railway scenes; the track layout. Beginning with a detailed examination of a number of simple layouts, this informative guide then shows readers how more complex plans can be developed. It explores the compromises that have to be made when creating a layout in limited space, and shows prospective modellers how to avoid creating track plans that would not be correct in prototype terms. Beautifully illustrated throughout with vivid, detailed pictures which are ideal for reference, this practical guide will help modellers of all abilities to enhance their recreated railway scenes and to achieve the very highest level of accuracy in their layouts.

Free Download Aspects of Modelling: Road Vehicles For Model Railways By Ian Moreton
2007 | 79 Pages | ISBN: 0711031541 | PDF | 34 MB
Over recent years there has been an increasing trend in railway modelling circles to replicate not just the railway itself, but also, the broader environment in which the railway was found. This involves recreating the whole townscape or countryside in which the railway operated, realising that the backdrop to the route portrayed is now as much a part of history as the locomotives and rolling stock that operated on it. This book takes the modeller, both the beginner and the more experienced practitioner, through the complex subject of adding road vehicles to their layout. Providing useful information about scale, relevance, operation and much more, it offers all modellers a detailed guide to a subject which can be confusing, but which, if got right, will greatly enhance the appearance and authentic look of any model railway. Profusely illustrated throughout, this third title in our new ‘Aspects of Modelling’ series, will be of use to all modellers, irrespective of the scale in which they are working.

Free Download Modelling Atomic Arrangements in Multicomponent Alloys: A Perturbative, First-Principles-Based Approach
English | 2024 | ISBN: 3031620208 | 222 Pages | PDF EPUB (True) | 29 MB
This book provides a comprehensive overview of a computationally efficient approach for modelling the phase behaviour of multicomponent alloys from first principles, describing both short- and long-range atomic ordering tendencies. The study of multicomponent alloy systems, which combine three or more base elements in near-equal ratios, has garnered significant attention in materials science due to the potential for the creation of novel materials with superior properties for a variety of applications. High-entropy alloys, which contain four or more base elements, have emerged as a particularly fascinating subset of these systems, demonstrating extraordinary strength and fracture resistance, among other desirable properties. The book presents a novel modelling approach for studying the phase behaviour of these systems, which is based on a perturbative analysis of the internal energy of the disordered alloy as evaluated within the Korringa-Kohn-Rostoker (KKR) formulation of density functional theory (DFT), using the coherent potential approximation (CPA) to average over chemical disorder. Application of a Landau-type theory to an approximate form of the Gibbs free energy enables direct inference of chemical disorder/order transitions. In addition, the perturbative analysis facilitates extraction of atom-atom effective pair interactions for further atomistic simulations. The connection between the arrangement of atoms in a material and its magnetic properties is also studied. By outlining and applying the proposed modelling techniques to several systems of interest, this book serves as a valuable resource for materials scientists, physicists, and chemists alike, seeking to understand and develop new alloy systems with enhanced materials properties.
