Research Abstract

We tried to develop cell assembly for deformation experiment using the solid medium deformation apparatus installed at Hiroshima Univ., which can be used to obtain the mechanical data of Mg_2GeO_4-olivine during transformation to its high pressure phase. In the result, we only succeeded to develop the good cell assembly, which can be applied to the deformation experiment at the condition of strain rate : 10^<-5>-10^<-6>/sec, pressure : 1GPa-2 GPa and temperature : up to 900C. However we need to conduct the deformation experiment up to almost 1200C conditions in order to clarify the initial problem. Now we know the key points for its development through the present research, therefore we will continue to improve the cell assembly.
