Tribological Behavior of Hastelloy C and Refractalloy 26
Figure 2
Microstructure of the Hastelloy C prior to testing (a) and that of the alloy subjected to the thermal cycle of the wear test at 400°C (b), as well microstructure of the Refractalloy 26 without modifications (c) and once it had been subjected to the thermal cycle of the same test (d).
