“…The SEM observations (Figure 8) indicated that the microwave-heated samples exhibited a finer and homogeneous microstructure when compared to samples prepared by other conventional sintering methods. Zhu et al [39] prepared and characterized Al-matrix composites containing α-Al2O3, Al3Ni and Al3Ni2 particulates, which were synthesized from Al and Ni2O3 powders by the microwave technique. Al-based alloy was initially mixed with reinforcement of 20% (volume fraction); the weight ratio of Al and Ni2O3 powders was 87.11%:12.89% (in wt.…”

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.

“…Recent years, reinforced particles have been used to strengthen the aluminum alloy, which was called particle reinforced aluminum matrix composite (PRAMC [1][2][3][4]). PRAMC is widely used in many fields such as automotive and aerospace for its various advantages, such as high specific strength, formability, weldability, low thermal expansion coefficient as well as wear-resisting property [5,6].…”

The hot deformation tests of in situ ZrB 2 and Al 2 O 3 nanoparticles reinforced AA6016 matrix composite were studied at deformation temperature of 300°C-450°C and strain rate of 0.001-1 s −1 . In this paper, the ZrB 2 and Al 2 O 3 nanoparticles were successfully prepared by direct melt reaction method firstly. Based on experimental results, the flow stress increased rapidly with the increasing true strain and decreased with the increasing temperature. Constitutive equation of the composite can be established based on the Arrhenius constitutive model. The processing map based on dynamic material model showed two stable processable domains: Domain A(300-360°C/0.08-0.01 s −1 ), which was controlled by dynamic recovery and domain B(410-430°C/0.37-1 s −1 ), which was typical dynamic recrystallization structure. The microstructural changes of the samples after deformed were observed through optical microscope (OM), scanning electron microscope (SEM) and transmission electron microscope (TEM). It was concluded that these two kinds of reinforced particles can greatly promote recrystallization nucleation at high temperatures. Thus, domain B is optimum hot processing window.

“…So compared with matrix metal, composite material has better mechanical properties at both room and high temperature. In this experiment, we use the thermal explosion reaction technology to in situ synthesize the NiAl matrix composite from Ni-Al-Ti-B system, explore the process and product of the composite materials, thus, provide a new direction for the preparation of the NiAl inter-metallic compounds [3][4][5][6][7] .…”

In situ synthesis technology was used to synthesize the NiAl matrix composite reinforced by TiB 2 which were fabricated by induction heating furnace in this work. Modern testing technologies were applied to analyze the microstructures of the products and the reaction process. The results showed that the composite consisted of NiAl and TiB 2 phases. The ignition temperatures of Ni+Al→NiAl and Ti+2B→TiB 2 were approximately 626C and 1029C when heating in 20K/min. The activation energy of above reactions were mol k 86. 295 J and mol k 08. 113 J , respectively. TiB 2 phase with fine particle was uniformly distributed in the NiAl matrix in the form of hexagonal prism.
