Japan's Institute of physical and chemical research group announces 13 days, they successfully developed a rise in temperature will shrink of new alloy materials. If it is and thermal mixing of substances, and can produce regardless of temperature changes its shape remains unchanged material, which in the processing of precision instruments, and has broad application prospects. According to Japan's" Daily News" reported on 13, general metal objects such as heat will occur after the expansion, but this kind of new alloy materials instead of having a thermal shrinkage characteristics. Although there have been other countries developed a case of heat shrinkable material, but because of low strength, shrinkage rate is difficult to control, raw material prices and other reasons to expensive to be practical. The research team developed a new material with manganese, germanium and other common materials, shrinkage is easy to control and convenient processing, the most important is its high strength and is suitable for various instruments. A member of the research team in division Kang said, the new materials of the invention enables the fabrication of temperature insensitive nanoscale processing tools possible, and this patent to Japan to bring considerable economic benefits. |
