“…As can be seen by comparing the data collected in Tables 7 and 9, E b and E of Ref steel are comparable while E b for rapidly solidified alloys are substantially lower than E. Keeping in mind the grain size difference across the sample radius, given in Table 5, it could be explained by sample anisotropy. According to Lucca et al [80], in the test in which the maximum penetration depth is kept constant for a period of time, the measured change in force is defined as indentation relaxation R ind [81,82]:…”
