“…Scudino et al [31] and Kim et al [32] have observed a 60%-90% increase in the compressive strength of high volume fraction of Zr-and Ni-base glassy metal particles in Al and brass matrices produced by microwave sintering compared to the powder metallurgy technique. Others have also reported the enhancement of compressive strength in Mg and Al-matrices reinforced with Zr-, Cu-and Fe-based glassy ribbons processed by powder metallurgy-based hot compaction through the induction heating method [32][33][34][35]. The processing techniques involved in these reports limit the particle dimension of the composites (4-10 mm in diameter), which has a greater impact on the compressive strength of the composites.…”

Aluminum metal matrix composites (AMMCs) are light-weight materials having wide-spread use in the automobile and aerospace industries due to their attractive physical and mechanical properties. The promising mechanical properties of AMMCs are ascribed to the size and distribution of the reinforcement, as well as to the grain size of the matrix. Microwave rapid sintering involves internal heating of aluminum compacts by passing microwave energy through them. The main features of the microwave sintering technique are a short processing time and a low energy consumption. The aim of this review article is to briefly present the microwave rapid sintering process and to summarize the recent published work on the sintering and properties of pure Al and Al-based matrix composites containing different reinforcements.

“…In metal matrix composites reinforced with particles of metallic glass, the latter perform both functions being a binder at the sintering temperature and a hard reinforcement in the composite at its service temperature. 34)37) The role of a binder can be played by metallic glass thanks to the existence of the supercooled liquid region (¦T x = T x ¹ T g , where T x is the crystallization temperature and T g is the glass transition temperature of the metallic glass), within which the metallic glass becomes soft. Distributed along the boundaries of the alloy matrix particles, the metallic glass particles help fully eliminate the porosity during consolidation, as was suggested in ref.…”

Sintering of powder mixtures is one of the widely used production methods of composite materials. The distribution of the reinforcement phases in these composites is a function of both initial powder structure and sintering conditions. Based on the recent literature and experimental results obtained by the authors, this article discusses a specific type of reinforcement distribution®the network distribution®in composites produced by sintering of powder mixtures. Examples of the influence of networks of different nature on sintering of metal and ceramic matrices are presented for continuous structures composed of carbon nanotubes and quasi-continuous structures of smaller particles located at boundaries between larger particles. The principles of the microstructure formation in composites with networks formed by ceramic particles, particles of metallic glass and carbon nanotubes are analyzed. Unusual properties of composites with metal and ceramic matrices achieved by organizing reinforcements in networks are discussed.

“…We chose three kinds of bulk glassy alloys, i.e., Cu 54 [49][50][51] . By sintering the mixture of Al powder and the FeCo-based glassy alloy powder at around T g , fully dense composite alloys are produced and exhibit a rather high compressive yield strength of about 600 MPa in conjunction with large strain of about 12% 51 . The yield strength level is comparable to weight reduction by about 60%.…”

In recent years, there has been a strong demand of developing advanced structural materials with functional properties such as high specific strength, high elevated temperature specific strength, high fatigue specific strength, low corrosion loss and low wear loss. This is because the practical uses of these functional structure materials are expected to cause the saving of material amount, reductions of material cost and energy during material production as well as the saving of consuming energy during practical uses. Besides, the light-weight materials with high corrosion resistance and high wear resistance are effective for the increase of endurance limit and the lightening of final products. Thus, the development of novel Al-based alloys having simultaneously the above-described functional properties is particularly important nowadays.As strengthening mechanisms for Al-based alloys, the following seven mechanisms are generally known 1 : solid solution, grain size refinement, work hardening, age hardening, precipitation, dispersion and defect-induced solute segregation. We have also noticed that the use of rapid quenching enables highly supercooled liquid solidification in conjunction with a high nucleation rate and low growth rate. By utilizing the high nucleation rate and low growth rate phenomenon, we have synthesized various kinds of metastable phases which change from nanocrystalline base structure to bulk glassy base structure through an amorphous base structure with increasing quenching effect (cooling rate). It is also known that the quenching effect is dominated by cooling rate from melt resulting from rapid solidification processes as well as by supercooling capacity of alloy liquid depending on alloy component and composition.When we focus on the strengthening caused by metastable phases, the effect is due to the combination of solid solution + ultra-high density of defects for amorphous phase and dispersion + grain size refinement + segregation for nanocrystalline phase. The amorphous plus nanocrystalline mixed phase alloys are expected to have simultaneously almost all the strengthening mechanisms. By utilizing the combined strengthening mechanisms of these metastable phases, we have tried to prepare novel Al-based alloys with the high tensile strength exceeding 1500 MPa at room temperature, high elevated temperature strength above 500 MPa at 573 K, high rotating beam fatigue strength above 400 MPa at 10 7 cycles, high elevated temperature fatigue strength above 100 MPa at 673 K after 10 6 cycles and high corrosion resistance below 20 mm/year in 0.25 M NaOH aqueous solution at 293 K. In addition, these Al-based alloys have been requested to exhibit a low wear loss, low coefficient of thermal expansion and low material density etc. This paper presents the review of the development achievements of metastable Al-based alloys obtained in our group on the basis of the above-described backgrounds and objectives. This paper reviews the features of alloy components, structure and mechanical properties, p...
