        摘要：The present research and development of classic cast aluminum alloys, AlSi, AlCu et al, have been reviewed in this paper. The aluminummatrix composites has also been reviewed. However, faced the challege of 21st century, the classic material must be connected with the development of advanced manufacture technology and casting process technology. Furthermore, with the development of modern industry, new cast aluminum alloys need to be developed and researched.

        摘要：Metal matrix composite may be one of the most attractive engineering materials in 21 st century. More attention is paid to short fiber and ceramic particulate reinforced metal matrix composites. Aluminum alloys and magnesium alloys are the best candidates for matrix, while ceramic particulate is in the investigator’s good graces due to its excellent properties. Addition of reinforcement in metal matrix could lead to the increase of strength, modulus, hardness and wear resistance, the improvement of the performances at elevated temperature and fatigue strength, and the decrease of the coefficient of thermal expansion, but to the decrease of ductility and toughness. Over the last two decades, a variety of techniques has been evolved in an attempt to successfully manufacturing particulate reinforced metal matrix composites （PRMMCs） and to optimizing the microstructure and mechanical properties. Accordingly, the process can be classified into three categories: （1） liquidphase process, （2） solidphase process and （3） twophase process. The interfacial chemical reaction between metal matrix and reinforcement depends upon many factors, such as fabrication process, composition of matrix and reinforcement, temperature and time. On the other hand, it shows a great influence on the fabrication process and the properties of composites. It is one of the most important task of investigations to understand and control the interfacial reaction in order to make it favorable to the processing and properties of PRMMCs. Discussion of techniques and interfacial reaction and control in PRMMCs is focused on present paper.

        摘要：The history and the general conditions of LP die casting in the world, the LP die casting machines and their famous suppliers are introduced in the paper. Now, there are still a lot of troubles in equipment, technology, die and automation in domestic LP die casting production, that will be overcome in the 21st century. The author’s emphasis on the key problem of LP diecasting is that LP die casting equipment must meet the needs of technologies and create a steady casting condition so that qualified products and high ratio of healthy products could be achieved.

        摘要：A set of complete technological system and theoretical basis has been established for squeeze casting technology during period of the past 60 years. Over 105 t of castings per annual was produced by this methed. As the development of Chinese automobile industry, the transfer of international industrial construction and Chinese entrance to WTO, squeeze casting technology will have to meet better opportunity and more powerful challenge in the soon coming 21st century. Therefore, it must penetrate into other subjects to boarden its large complicated product with high quality. In addition, new types of squeeze casting machines should be developed to replace the existing machines.

        摘要：The relationship between microstructure and properties of the reactive selfcomposing Al2O3/Al ceramic matrix composite was investigated in this paper. The results had shown that the bending strength and fracture toughness of the composite were affected by the content of aluminum alloy and porosity in the structure. When the metal content was about 20%￣30%, bending strength and fracture toughness of the composite reached 380￣420 MPa and 8.5￣9.5 MPa\5m12, respectively. The pore in the structure was very detrimental to properties of the Al2O3/Al composite. Especially, as the metal content in the composite was less than 10%, the pore was more detrimental to the properties.
