| Research Abstract |
Deformation experiments and in situ time-resolved stress-strain measurements were carried out at pressures of 14-17 GPa, temperatures of 1400-1700 K and strain rates of 3-15×10^<-5> s^<-1> by using a deformation-DIA apparatus and synchrotron radiation. This technical development enables us to investigate viscosity(creep strength) of wadsleyite, which is the most dominant mineral at the upper part of the mantle transition zone.
