In polycrystalline Ni, Nabarro-Herring diffusion creep was found to be the rate controlling creep mechanism at a certain temperature.
At that temperature, if the steady state strain rate is 10-8 s-1 at a stress of 10 MPa, the steady state strain rate of 10-9 s-1 will be obtained at a stress value of ______ MPa (in integer).
Assume that the same creep mechanism is rate controlling during the creep deformation.
At that temperature, if the steady state strain rate is 10-8 s-1 at a stress of 10 MPa, the steady state strain rate of 10-9 s-1 will be obtained at a stress value of ______ MPa (in integer).
