The atomised powder present a microstructure of an aluminium matrix reinforced with a spherical quasicrystalline icosahedral phase, in the range of nanometre in size. The powder was consolidated into bars using warm extrusion. The microstructure of the extruded bars retains the quasicrystalline microstructure and the bars present outstanding mechanical properties, i.e. proof stress of 280 MPa at 300 °C. Upon heating the microstructure evolves towards the equilibrium. The thermal evolution was investigated by means of x-ray diffraction, differential scanning calorimeter, scanning electron microscopy and transmission electron microscopy. According to these observations a transformation in two steps is proposed. A first step consists in the decomposition of the supersaturated solid solution of the matrix and the quasicrystals, and a second step in the transformation of the quasicrystals into the equilibrium phases.

The highly beneficial effect of LSP treatments has been demonstrated in the extension of life of test specimens with induced surface notches. The application of the LSP treatment to concrete high reliability components, particularly in the field of metallic materials of biomedical interest is envisaged. In the present communication, several experimental examples of the effects introduced in this kind of materials are shown along with some computational design tools developed in relation with typical prosthetical components. Additionally, the prospects for the application of the LSP treatment to new/advanced materials of biomedical interest are discussed.

Biodegradable polymers and magnesium (Mg) alloys have played an important role writing the history of resorbable implants [1,2]. This paper presents the processing by extrusion/compression moulding, mechanical characterization, thermal characterization and in vitro biocompatibility of a novel generation of resorbable materials based on a polymeric matrix reinforced with metallic Mg particles.
