Desarrollo de aceros reforzados con carburos primarios vía metalurgia líquida

The steel reinforcement by means of the addition of primary carbides via liquid metallurgy needs to fulfil two essential requirements to be technically viable: the development of a solid reinforcing product which is appropriate to be mixed with the steel and the optimisation of the metallurgic addition of these reinforcing particles into the liquid steel. Besides, the improvement of the reinforced alloy characteristics is directly related to the particles' nature of reinforcing particles, their homogeneous and uniform distribution in the matrix and their size and morphology. The manufacture of these carbides by SHS ('Self propagating High temperature Synthesis') and their addition before steel is poured into moulds allows achieving the above-mentioned conditions.
