Journal ArticleDOI
Microstructure and mechanical properties of an Al–TiC metal matrix composite obtained by reactive synthesis
Nassim Samer,Jérôme Andrieux,B. Gardiola,Nikhil Karnatak,Olivier Martin,Hiroki Kurita,Laurent Chaffron,Sophie Gourdet,Sabine Lay,Sabine Lay,Olivier Dezellus +10 more
TL;DR: In this article, a metal matrix composite was obtained by a novel synthesis route, reacting Al 3 Ti and graphite at 1000°C for about 1min after ball-milling and compaction.
Journal ArticleDOI
Microstructural and mechanical comparison of Ti + 15%TiCp composites prepared by free sintering, HIP and extrusion
Jean-Baptiste Fruhauf,Jérôme Roger,Olivier Dezellus,Sophie Gourdet,Nikhil Karnatak,Nathalie Peillon,Sébastien Saunier,Frank Montheillet,Christophe Desrayaud +8 more
TL;DR: In this paper, three different powder metallurgy techniques: free sintering, HIPing, and direct powder extrusion were compared and the correlation between the microstructural features and the mechanical properties was discussed and the processes are compared.
Journal ArticleDOI
Transformation Kinetics and Resulting Microstructure in MMC Reinforced with TiC Particles
Mickael Mourot,Alice Courleux,Moukrane Dehmas,Elisabeth Aeby-Gautier,Guillaume Geandier,Olivier Dezellus,J.C. Viala,Olivier Martin,Nikhil Karnatak,Frédéric Danoix +9 more
TL;DR: In this paper, the phase transformation kinetics on cooling and resulting microstructures of steel-based matrix composites (MMC) reinforced with TiC particles by powder metallurgy were studied.
Journal ArticleDOI
