Characterization of fretting fatigue in self-piercing riveted aluminium alloy sheets
Han, L.; Chrysanthou, A.; Young, K. W.; O'Sullivan, J. M. (2006)A study was conducted to characterize fretting fatigue in self-piercing riveted single-lap joints of aluminium alloy 5754 sheets. The experimental results showed that fretting occurred at three different positions in the ... -
Chord line force versus displacement for thin shallow arc pre-curved bimetallic strip
Angel, G. D.; Haritos, G.; Chrysanthou, A.; Voloshin, V. (2015-01-01)A pre-curved bimetallic strip that is applied with a force in an axial orientation, i.e. along its chord line, exhibits nonlinear force-displacement characteristics. For thin bimetallic strips, whereby the radius of curvature ... -
Combustion synthesis and subsequent sintering of titanium-matrix composites
Chrysanthou, A.; Chen, Y.K.; Vijayan, A.; O'Sullivan, J. (2003-05-01)Titanium-matrix composites containing up to 50 wt% TiC particles were prepared by combustion synthesis using elemental powders. The products were subsequently sintered at 1160°C for various periods of time. SEM and X-ray ... -
Combustion synthesis in the Mo-Si-Al ternary system
Bhaduri, S.B.; Huang, J.G.; Bhaduri, S.; Chrysanthou, A. (1998)Combustion synthesis reactions were investigated in the Mo-Si-Al ternary system along the MoSi-MoAl tie line. The experimental data show that addition of Al helps the exothermicity of the reaction, presumably with the help ... -
