Abstract
High technology transport sectors are looking for higher performance materials, competitive in terms of cost, lighter than conventional titanium alloys and recyclable, which could improve efficiency of several components and reduce fuel consumption through weight reduction. This work has been carried out in the framework of Growth NEWTIRAL project (Contract N°G5RD-CT01-00529) financially supported by the European Commission, which investigates the production of in situ Ti/TiB master alloy (with a high volume fraction of reinforcing phase) that is further melted together with titanium ingots. This way a composite with controlled TiB reinforcement volume fraction can be obtained via conventional casting route. This study focuses in the investigation of the production technique of the Ti/TiB master alloy, which is produce by SHS (Self Propagating High temperature Synthesis). This technique is a self-sustaining combustion process of any chemical compound that results in the formation of valuable condensed products. The SHS is based on the principle of maximum utilization of chemical energy of reacting substances (exothermicity) for obtaining inorganic compounds, materials, and items of various application purposes and also for organizing highly efficient technological processes. The obtained product is characterised using different techniques: XRD, SEM, and mechanical properties.
