Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
In recent times, there has been an increasing demand for dissimilar metal
fabrication, as this weldment utilizes the specific benefits of different metals for a
particular application. In this paper, the recent trends evolving in the field of dissimilar
material joining, which introduces residual stresses, distortions and formation of brittle
intermetallics within the structure is discussed. As these are highly undesirable,
therefore various techniques were studied by the researchers, which reduce the
distortions and formation of brittle intermetallics. The use of numerical techniques in
this field was also studied as they provided the researchers with an insight into the
process. Mostly, the joining of dissimilar material is done using friction stir welding
and laser welding, but the use of friction stir welding has constraints in terms of
material temperature thus, the joining of dissimilar weldment is discussed by giving a
special context to laser welding technology.
