Metal Casting Technologies : December 2008
GREEN FEATURE renewable energy technologies, more efficient conventional technologies, energy storage systems and carbon capture and storage. In the next keynote address, “Climate Change in the Context of Material Technology”, the focus turned to the effects of climate change in Thailand when Anond Snidvongs from the Southeast Asia START Regional Centre , based at Chulalongkorn University in Bangkok, gave some projections about the future climatic conditions under different greenhouse gas emission scenarios. He said that over the last 10-15 years frost in the cool season has all but disappeared from the mountain regions in the north of Thailand. If the “business as usual” situation continues then it is predicted that over next 10-20 years Thailand will have longer and drier hot seasons with shorter cool seasons. Rainfall will remain the same but there will be fewer rainy days. Potential dangers are from drought in the longer drier periods, flooding due to more intense rain and fewer but more violent storms. There would be changes in raw material supply especially from agricultural sources, water limitation and/or supply inconsistency, and in consumer requirements. Prizes are lead free The best paper award for the metals sessions at MSAT-5 was given to Katsuyoshi Kondoh and Hisashi Imai from Osaka University, Japan for their presentation on “Environmentally Benign Pb-free Cu-Zn Alloys Dispersed with Graphite Particles via Powder Metallurgy Processing and Their Mechanical Properties”. Also held during MSAT-5 was the 12th Annual Contest for the Thainox Metallurgy Award 2008 presented by Thainox Stainless plc to encourage young Thai metallurgical researchers. The winner at post-graduate level was Miss Wanthanee Sithiloh from Chulalongkorn University for her work on “High temperature tensile tests of lead free copper alloy castings simulating the machinability”. Other young researcher awards at MSAT were made in the field of surface engineering by the Thai Parkerizing Company of Thailand. Metallurgy for sustainable development Following MSAT-5 The 2nd Thailand Metallurgy Conference (2 TMETC) was also held in Bangkok from 16-17th October under the banner of “Metallurgy for Sustainable Development”. The conference was hosted by King Mongkut’s University of Technology (KMUTT) as part of the celebrations for this institution’s 48th Anniversary. During this event the Thailand Metallurgist of the Year award was made to Dr. Chatchai Somsiri, Metallurgy Director of Thainox Stainless Plc., situated in Rayong province. Earlier at MSAT-5, Dr. Chatchai had given an invited presentation on “Unseen Roles of Nickel Alloys on Environmental Preservation and Reduction in Global Warning”. Altogether 40 papers and 10 posters were presented to show Mark Radka gives an international perspective on materials research and climate change at MSAT-5. Waste is gold Recycling was the subject of the final keynote talk by the Wongpanit Company the recycling message being highlighted as “Waste is Gold”. The Wongpanit Garbage Recycle Separation Plant which is situated in Phitsanulok in the north was the first recyclable waste separation plant in Thailand; it is certified to ISO 14001. It can handle 500 tons of recyclable waste per day dealing with metal, plastic, glass, paper, electronic waste, and other industrial materials . Wonpanit places emphasis on public relations to educate people in both reducing waste and in separating waste at home so that it can be more efficiently recycled. 34 www.metals.rala.com.au how metallurgical developments can contribute to reducing environmental demands and waste and to energy conservation by improving the efficiency of manufacturing processes, the performance, reliability and life of parts, and the ease of recycling. For example, Dr. Wannasin from Prince of Songkla University reviewed the benefits of semi-solid Al casting processes in terms of reduced defects from gas and shrinkage, reduced machine cycle times, lower cost machines, shorter heat treatment times and the possibility of casting “wrought” type alloys, etc. Early in the New Year Thai chemists will also debate environmental matters when they address “Sustainable Development in Chemistry Based on Indigenous Knowledge” which is the theme of PACCON 2009 - the next Pure and Applied Chemistry International Conference. This event  is being organized by the Chemical Society of Thailand and Naresuan University and will be held from 14-16th January in Phitsanulok.
