| Research Abstract |
It is known to be difficult to fabricate large-sized bulk metallic glasses by conventional method and also difficult of their machining and plastic working. The present study aims to fabricate large-sized and complex three-dimensional metallic glasses by the use of the method based on Selective Laser Melting (SLM). Optimum conditions for laser irradiation to fabricate metallic glasses SLM specimens have been investigated with the use of powder mixtures which consist of all the elements of multicomponent alloys with high glass-forming ability. The components of alloys and the building conditions in order to obtain metallic glasses SLM specimens easily were found.
