In order to improve the limited plasticity of bulk metallic glasses, the main idea is to introduce some inhomogeneity, ranging from atomic scale to micrometer scale. Two main routes have been reported in the literature to introduce this inhomogeneity: either by monitoring the chemical composition so as to induce a controlled and limited crystallization during the solidification phenomenon (in-situ composites) or by introducing crystalline particles which are not modified during the manufacturing of the bulk metallic glass matrix (ex-situ composites). Both methods offer advantages and drawbacks. The development of MGMC has been reported mainly in the Zr-based metallic glasses, and more recently in Ti-based alloys. The aim of the present work is to compare Ti-based MGMC produced by direct solidification with more conventional Ti-based BMG. The mechanical properties of these materials are characterized, mainly those corresponding to the plastic behavior.
