“…In another work, (Yoshikawa et al, 2003) The microstructural studies showed that the reinforcements were uniformly distributed throughout the specimens examined. In addition, it was reported that the composite materials prepared using scrap exhibited a little higher strength and hardness than Al/Al 2 O 3 composites, and did not break into pieces upon fracture, as occurred in the case of (Al-10 at.% Fe)/Al 2 O 3 samples.…”

In this contribution, authors present a review on the state-of-the-art in the utilization of industrial and agricultural waste materials for the development of metal-matrix composites (MMCs), providing, through the judicious analysis of an ample and varied references source -from the oldest to the newest ones -, an insight into the challenges and opportunities for the exploitation to their full potential. In addition to its topicality, the novelty of this contribution lies in the presentation of key statistical, technical and property-related information of a comprehensive variety of waste materials classed into two main groups, namely, fly ash reinforced MMCs and MMCs derived from other waste materials. Although fly ash has been exploited in a broad range of applications, the attention paid for its use in the development of MMCs seems to be insufficient. A purposely designed chart helped to pinpoint the more demanding and profitable applications of fly ash, and establish strategic opportunity areas. With the exception of the recent utilization of fly ash for the automotive industry, virtually no other waste material has been reused for a specific industrial application. In this context, by identifying five reasons for this Downloaded by [University of Nebraska, Lincoln] at 08:41 26 August 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 observed delay, an essential goal of this review is arouse the interest of academicians, scientists/technologists and industrialists in the use of those materials for the fabrication of MMCs. In the case of agricultural materials, a two-fold perspective may apply, because while on the one hand, certain chemical elements have to be removed for specific applications, on the other hand, recovery of certain elements might be more attractive. Based on the significant progress observed so far, in terms of scientific and technological research, a promising future can be anticipated. The proper use of industrial and agricultural waste materials entails knowledge generation as a prerequisite for incubation of pilot-plant and industrialization stages, culminating with all related benefits to society.

“…5) It has been demonstrated that the reaction rate and the mechanical properties are not deteriorated very much if the Al is replaced with the synthesized Al scrap. In the above process, 4) vitreous (pure) silica was utilized as the raw materials, however it is expensive and better to make use of the other silica-based wasted materials. There are many kinds of wasted glasses.…”

Model experiments were performed for fabricating composite materials using Al scrap and waste glasses. Significance of the fabrication using the waste matters was discussed from an environmental point of view. Al alloy having composition of the Al scrap was melted and infiltrated into a soda-lime glass beads' bed by a vacuum process. Reaction layer was formed at the interface between the glass beads and the molten Al alloy. The layer thickness of 50 microns was obtained after 1 h reaction. The composite materials showed a strong bonding between the filler (the glass particles) and the matrix. Variation of the layer thickness was measured at various conditions of the reaction time and temperature.Distribution of the metal elements in the microstructure of the composite material was analyzed with SEM/EDX. It was shown that not only Si but also some elements were removed from the glass to the Al alloy matrix. Behaviors of the other elements were discussed, considering the thermodynamics. Compression test of the composite materials was performed. They fractured in a brittle manner once, however, after the fracture, they were not broken into pieces, but followed by the ductile deformation.

“…Amphoteric oxide Al 2 O 3 is a common crucible material; its stability is better than that of acidic oxides. Yoshikawa et al (2003) reacted waste-Al with acidic SiO 2 to prepare composite materials. Basic oxides such as MgO and Y 2 O 3 are again more stable than amphoteric oxides.…”

Purpose When smelting Al-Li alloy, the material inevitably comes into contact with various oxide-refractories. These refractories are subjected to varying degrees of melt-corrosion at high temperatures. The purpose of this study is to find stable oxide refractories at casting temperature. Design/methodology/approach Four materials were selected for evaluation, and their corrosion by the Al-Li alloy at casting temperature and different holding times was measured. Subsequently, scanning electron microscopy and energy-dispersive spectroscopy were used to study the interfaces. Stable refractory materials were selected by comparing the thicknesses of the reaction layers. Findings The thickness of the Al-Li/ZrO2 reaction layer varies linearly with the square root of the holding duration. Therefore, the growth of the reaction layer is controlled by diffusion. The reaction layer of Al-Li/Al2O3 is thinner, and its growth is also controlled by diffusion. However, there were no obvious reaction layers between the Al-Li alloy and MgO or Y2O3. By comparing these reaction-layer thicknesses, the order of stability was found to be ZrO2 < Al2O3 < MgO and Y2O3. Originality/value These results provide a scientific basis for the optimal selection of refractory materials for Al-Li alloy smelting.
