Abstract:

The metallic glasses are knowing an increasing interest for the past decades. They exhibit very exceptional properties; however the main drawback is the limited size of the samples.The MBJ is a promising solution to obtain larger dimensions and high-resolution samples. Using SPS after MBJ process, ensure the production of high density, fully amorphous parts.In this study, a printing recipe has been found to get metallic glass green parts using the HERAEUS powder AMLOY ZR01. After finding that the curing and debinding steps have no influence on the amorphous character of the materials, a pre-sintering recipe in a sintering furnace has been developed. Meanwhile, after finding the parameters of the sintering process on the raw powder using SPS, the printed and pre-sintered parts have been sintered using SPS. The influence of carbon residues on the densification and stability of the materials have been discussed.
