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
Our work presents a comprehensive report on selective laser melting (SLM) techniques with a specific focus on the different material families compatible with the SLM process, the mechanical and microstructural characteristics, residual stress and defect analyses. The major process parameters that determine the geometric accuracy and post-treatment techniques that eradicate defects in SLM fabrication are also reviewed. Then, a keyword co-occurrence analysis is performed to determine the future research directions in the SLM. The results showed mechanical characteristaion of SLM, defect analysis of SLM, SLM fabrication of porous implants and bulk metallic glass production using SLM to be the four major domains in SLM literature.
