“…The data shown here were obtained from compression tests. Note that in A520 alloy and 6061 alloy matrices, there is no fracture (even for >20 % strain) and hence the ultimate strength and fracture strain values are not provided (Dudina et al 2009(Dudina et al , 2010Aljerf et al 2012 ) In a similar kind of work, Dudina et al ( 2010 ) reinforced Al-alloy A520 with Cu-based Cu 54 Zr 36 Ti 10 (at.%) glassy alloy (of 15 % V f ) by using high frequency induction sintering under pressure. The metallic glass ribbons prepared by arc melting/melt spinning were powdered in a vibratory mill for 24 h and mixed with the cut ribbons of Al-matrix (procedure similar to that in ref.…”

“…They observed a significant increase in the mechanical properties due to the grain refinement and the uniform distribution of the Fe-based metallic glass particles. 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].…”

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.

“…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 .…”

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...
