The Effect of Surface Alloying on the Fatigue Behavior of Aluminum and Titanium.

摘要

Sheet specimens of titanium 125,titanium 6Al-4V,and aluminum 2014-T6were tested in a constant deflection reverse bending machine with and without surface alloying. It was observed that for the chromium treated titanium 125,the endurance limit increased from 28,000psi to 41,000psi,an increase of 46%. No improvement in fatigue life of aluminum 2014-T6was observed with any of the coatings tested. (Author)
