Al-TiB₂: Un materiau alternatif pour des applications resistant a l'usure et aux hautes temperatures dans l'industrie du transfert

Results obtained in a study of real-life possibilities, process optimization and mechanical properties of aluminum metal matrix composites reinforced by particles of ceramic TiB₂ are presented and discussed. Vehicle and train components have been made of those materials by gravity molding, high-pressure casting and the so-called Pultipouring process. The results have been analyzed and evaluated from the standpoint of casting and mechanical properties. Reinforcement resulted in a significant improvement and the presence of TiB₂ made the alloy thixotropic, which had a positive effect on the process.
