Metal Casting Technologies : September 2005
ASIAN OVERVIEW THAILAND as skilled workers in the field of iron casting. During 2006 a similar training and examining/certification programme will operate in die-casting. Research in light alloys at KMUTT is lead by Dr. Chaowalit: the main areas include the influence of flux compositions on grain refinement efficiency and the application of Scandium as a grain refiner. The first paper from the work on Scandium in cast aluminum alloys will be presented at AFC9 -- the Asian Foundry Congress in Vietnam this coming October. Work is also under way on semi- solid processing of aluminum alloys in cooperation with King Mongkut's Institute of Technology (KMIT) North Bangkok and the Tokyo Institute of Technology in Japan. Casting research at Chulalongkorn University is concentrated in a special Solidification Laboratory in the Department of Metallurgical Engineering. The key staff members include Prof. Umeda, Dr. Suvanchai, Dr. Mawin, and Dr. Ittipon, who are all members of the Advisory boards of the Thai Foundrymen's Society and of the Iron and Steel Institute of Thailand. Like KMUTT they also provide technical seminars for industry including the "Die Casting University" programme operated with the Thai Foundrymen's Society. Currently 8 students are involved in post-graduate research in solidification. The main research themes include: • Casting Simulation of shaped castings and continuous castings • Fluidity of Aluminum Alloys • Deformation behaviour during Solidification of Aluminum Alloys and Steels • Castability, Machinability and Mechanical Properties of Lead Free Copper Alloy Castings • Solidification of Wear Resistant Cast Irons The Dept. of Metallurgical Engineering is designated as a Centre of Excellence (COE) in Casting Technology. Significant research areas receiving external funding include: • "High Quality Castings for the Automotive and Machinery Industries", which is financially 5 5. Activities on the two day Induction Melting Course for Industry held at KMUTT 6-7. Teaching activities on the post grad Masters course in Production Engineering at KMUTT 6 7 supported by the Thai-Japan Technology Transfer Project (TJTTP). • "The Foundry Master Plan", which is financially supported by the Iron and Steel Institute of Thailand (ISIT) to develop training and research towards the year 2010. • "High Temperature Deformation including the Mushy State", which is financially supported by Nippon Light Metals Co. Ltd. The aim is to study elevated temperature mechanical properties and behaviour, and to analyze ingot distortion/breakage phenomena in order to prevent breakage of DC ingots. • "Castability and Mechanical Properties of Lead Free Copper Alloy Castings and their Standardization ", which is supported by the Japanese Standards Association (JSA) and the Japan Non Ferrous Metal Castings Association. The Solidification Group have produced some 15-20 conference and journal papers during the past 12 months. Staff from the group will be presenting some of their research at AFC 9. At Chiang Mai University in the north of Thailand the writer is working with a small research group led by Dr. Torranin on the characterisation of the microstructural features of casting alloys including High Cr Irons, Duplex Stainless Steels and Precipitation Hardening Aluminium Alloys. Work on the study of eutectic and other carbides in 30% Chromium Irons using transmission electron microscopy (TEM) has lead to a number of international conference and journal papers, the latter including Acta Materialia and the International Journal of the Iron and Steel Institute of Japan. 40 www.metals.rala.com.au
