Figure 4-7:   Texture dependence of       (  ) (denoted by Fn in the figure) (fraction of radial hydrides) of specimens oriented as
                             indicated in Figure 4-6, containing 60 to 90 wppm hydrogen, loaded at 160 MPa and cycled through the temperature
                             range from 355 to 160C five times (from [Sakamoto & Nakatsuko, 2006]).








































                  Figure 4-8:   Applied stress dependence of       ′(  ) (fraction of ‘radial’ hydrides relative to the value of       (0) at zero load with the
                             former denoted by Fn in the figure) cycled five times between 355 to 160C with an externally applied tensile stress of
                             160 MPa for specimens containing 61, 130 and 251 wppm hydrogen and with an externally applied tensile stress of
                             130 MPa for specimens containing 135, 239 and 668 wppm hydrogen. All tests were done with specimens oriented in
                             the WD (from [Sakamoto & Nakatsuko, 2006]).
