Effects of thermomechanical processing on microstructure and hardness profiles in AA6061 plates
… (?) and temperature (T) - on grain structure and hardness evolution in AA6061 plates were investigated by simulating the rolling process using plane strain compression (PSG). Particular emphasis was exerted on understanding the impact of the variables on the overall mean grain size and hardness, …

Dynamic hardness testing challenges conventional tests
The design and use of a portable dynamic hardness tester is described. The thesis begins with a description of the more common static hardness tests and the usefulness of such tests in industry. It shows a correlation between the different types of hardness and also between hardness and other …

Characterization of cyclic plasticity type wear mechanism for titanium alloy, TI-6AL-4V on reciprocating sliding wear test
… frequency for both contact pins cylinder. The hardness shows high value at 200 N, 20 cycle and 2.5 Hz of frequency. Contact pin Ø6.5 mm experienced greater wear width, wear area and hardness due to high contact pressure applied during the sliding. The cyclic plasticity presences following …
