 The 9th China International Diecasting Congress and the 1st International Symposium on Nonferrous Alloys and Special Casting Technologies (ISNASCT) were successfully held in Shanghai on July 19-22, 2014. Both events were jointly sponsored by Chinese Mechanical Engineering Society, Die Casting Commission of World Foundry Organization and Non-Ferrous Materials Commission of World Foundry Organization, and organized by the Foundry Institution of Chinese Mechanical Engineering Society (FICMES) and China Productivity Promotion Center of Foundry Industry.
    The opening ceremony of the congress was held on the morning of July 20. Dr. Su Shifang, Secretary-General of FICMES, presided over the opening ceremony. Approximately 150 delegates from China, Switzerland, Germany, Italy, USA and Japan participated in the conference.
    A total of 29 papers were collected for the 9th China International Diecasting Congress, and 19 experts, scholars, and delegates of enterprises at home and abroad made wonderful technical presentations. Their presentations covered such topics as: the current cutting edge and hot topics of die casting materials, technologies and equipment, typical case study on the production and management of die casting enterprises, the development status of the die casting industry, and so on. Their topics included: the latest research progress and application of high pressure, low pressure, squeeze casting and vacuum die casting technologies; the latest technology and application of die casting machines; computer numerical simulation in the design of die casting processes; analysis of microstructures and properties of die castings;  research and development of new die materials; development and application of multi-functional metal plating technology and infiltration technology to die castings; the concept of green environmental protection in production and equipment development of the die casting industry.
    A total of 31 papers were collected for the 1st International Symposium on Nonferrous Alloys and Special Casting Technologies. Fourteen delegates from colleges and universities, research institutes and production enterprises gave presentations at the symposium. Their topics covered casting materials, casting processes, measurement methods, defect study, numerical simulation, and so on. On the whole, the presentations on casting materials research accounted for a large proportion. Meanwhile, the topics of the presentations show that the current research on non-ferrous alloy materials tends to diversify. The focus was not only on the most popular materials in recent years such as magnesium alloys and aluminum alloys, but also titanium alloys, copper alloys and composite materials. The application of the developed materials is not merely limited to the aerospace and automobile industries, but has gradually extended to the field of biological materials. The casting processes and technologies concerned include investment casting, die casting, thixoforming, spray forming, as well as metal solidification and control.
    Professor Su Yanqing of Harbin Institute of Technology gave a presentation entitled "Development of lamellar orientation controlling in TiAl intermetallics by directional solidification". He introduced in detail the properties of TiAl-based alloys and their anisotropic characteristic, and demonstrated how to modify the lamellar orientation by two different directional solidification processes, namely seeding technique and adjusting the solidification path. He reviewed the principles of the two methods and compared the advantages and disadvantages of the two methods in engineering applications. He pointed out that to accurately control the lamellar orientation to be suitable for large scale industrial production, the laws between the lamellar orientation and the directional solidification parameters should be established. 
    Professor Jie Wanqi of Northwestern Polytechnical University, also having many years of research in the field of solidification control, emphatically introduced the solidification characteristic of multi-component alloys and its application to casting in his presentation. He illustrated the effects of overheating treatment and the addition of refining agents on the solidification microstructures of alloys, and showed how to control the microstructures and properties in casting production by showing examples of cast A356 alloys. 
    Professor Ma Naiheng of Shanghai Jiao Tong University has a lot of in-depth research on the preparation of aluminum matrix composites. He presented a controllable melt synthesis route to produce high quality high strength particle reinforced aluminum matrix composite material, and he finally successfully prepared the composite material with the reinforcement particles uniformly distributed in the matrix. His report aroused great interest among the delegates.
    Gas porosity is a big problem of vacuum die castings. Professor Xiong Shoumei of Tsinghua University gave a solution in his presentation. He studied the effects of vacuum condition, divider cone, runner and filling velocity on the microstructure and mechanical properties of vacuum die casting magnesium alloys. He pointed out that controlling the vacuum degree and filling velocity can reduce the gas porosity and improve the grain refinement. His research results are valuable for the application of the process.
    Casting computer simulation technology has been more and more widely applied to important, complex and large casting parts, and it has also been paid more and more attention by production manufacturers. Dr. Yin Yajun of the InteCAST software research & development team of Huazhong University of Science and Technology introduced the latest research and achievement of the InteCAST-casting CAE software applied in nonferrous alloys and special casting processes, including multiphase flow interface capturing, automatic fault tolerance, macro/micro structure prediction, stress prediction analysis, metal smelting process simulation and heat treatment simulation, intelligent casting  process optimization, and so on. Mr. Wu Guanghui of MAGMA Engineering (Suzhou) Co., Ltd. introduced how to optimize wheel castings and their casting processes by implementing casting CAE technologies.
    Professor Hiromi Nagaumi, Aluminum Corporation of China, and Professor Han Qingyou, Purdue University of USA, were welcomed by the delegates since their topics were closely related to the production practices. Professor Hiromi Nagaumi mainly introduced his basic research achievements on the cracking of aluminum alloy materials. By studying the high temperature properties of the two-phase regions of the 2xxx, 6xxx and 7xxx series aluminum alloys, he obtained the stress-strain curves and established the relationships between temperature, tensile strength, and elongation. He concluded that ZST (zero strength temperature) could be used as a criterion of cracking. His research results have a practical significance on the prevention of cracking. Professor Han Qingyou systematically analyzed the mechanism of die soldering on a bare steel die/core pin and on a coated die/core pin material during the diecasting operations. He investigated the effect of temperature on die soldering, and his research results provide a theoretical basis for reducing the defect of die soldering and increasing the productivity during the practical diecasting operations.
