In this memorandum, the available reports in DMIC which are concerned with welding of metal surfaces in space environments, whether this welding is desirable or undesirable, are reviewed. The phenomenon of surface welding in the space environment is of interest to many for various reasons. Some hope to use the phenomenon for the completion of attachment joints or repairs to spacecraft. Some are concerned because of the possible malfunction of moving components such as bearings, valves, and electrical contacts. However, no effort has been made to correlate and analyze the data that are presented. A section on fundamental studies also is included, along with an annotated bibliography which covers references dealing primarily with lubricants, lubrication, coatings, and test equipment.

This is one of the first books describing in detail research and development work carried out in the former USSR and in the CIS countries in the area of welding in space. Information has been scattered throughout various journals and conference proceedings and this book presents a comprehensive picture of individual stages of development and construction of space stations. The authors describe in detail the work carried out at the E O Paton Electric Welding Institute (the main organisation working in this field).

This report supplies information on joining processes applicable to titanium and its alloys in sheet metal applications, primarily related directly to airframe construction. Although the material presented here does not cover all titanium joining processes, and omits such processes as plasma-arc, submerged-arc, electroslag, flash, and high-frequency resistance welding, the data presented cover materials up to 2-inches thick in some cases and the report should be useful to anyone seeking titanium joining information. The joining processes covered fall into five categories: welding, brazing, metallurgical bonding (diffusion and deformation bonding), adhesive bonding, and mechanical fastening. The fusion welding processes that are discussed in detail include gas tungsten arc, gas metal arc, arc spot, and electron beam. The resistance processes give extended coverage are spot, roll spot, and seam welding. (Author).

This book will be the last one in a series of 4 books issued yearly as a deliverable of the research school established within the European Network of Excellence CMA (for Complex Metallic Alloys). It is written by reputed experts in the fields of metal physics, surface physics and chemistry, metallurgy and process engineering, combining expertise found inside as well as outside the network. The CMA network focuses on the huge group of largely unknown multinary alloys and compounds formed with crystal structures based on giant unit cells containing clusters, with many tens up to more than thousand atoms per unit cell. In these phases, for many phenomena, the physical length scales are substantially smaller than the unit-cell dimension. Hence, these materials offer unique combinations of properties, which are mutually excluded in conventional materials: metallic electric conductivity combined with low thermal conductivity, combination of good light absorption with high-temperature stability, combination of high metallic hardness with reduced wetting by liquids, electrical and thermal resistance tuneable by composition variation, excellent resistance to corrosion, reduced cold-welding and adhesion, enhanced hydrogen storage capacity and light absorption, etc. The series of books will concentrate on: development of fundamental knowledge with the aim of understanding materials phenomena, technologies associated with the production, transformation and processing of knowledge-based multifunctional materials, surface engineering, support for new materials development and new knowledge-based higher performance materials for macro-scale applications.
