Researchers say that several additional microstructural analyses are needed in order to fully understand the alloy’s mechanics and its ability to recover from exposure to high stresses. “Our ultimate goal is to invent a novel ul- trahigh temperature material superior to nickel-base superalloys and replace high-pressure turbine blades made of nickel-base superalloys with new turbine blades made of our ultrahigh temperature material,” says Yoshimi. www.tohoku.ac.jp/en. VIBRATION INSULATION FOR DIESEL LOCOMOTIVES Scientists at Samara University, Russia, are developing a vibration in- a 25-year quality warranty for locomo- tives, and a 15-year warranty for space equipment. www.ssau.ru/english.

The vibration in- sulating devices will be made of metal rubber (MR) material, a unique damp- ing material developed by the Samara scientists and produced in the universi- ty’s laboratories. MR material features the useful properties of rubber, while at the same time withstanding aggres- sive agents, high and low tempera- tures, and other adverse external fac- tors. Scientists say the secret lies in the special technology of plaiting and pressing the spiral metal strands of varying diameters. Dampers produced by this meth- od and based on the MR material are used successfully in producing Russian space equipment. Due to their all-metal structure, items made of MR material easily withstand temperatures to 400°C and also have high service life indica- tors, because deterioration processes develop relatively slowly in them. For example, MR vibration insulators have
