Vpliv parametrov laserskega udarnega utrjevanja na zaostale napetosti v visoko-trdnostnih aluminijevih zlitinah
Jan Ahačič, Uroš Trdan, Laurent Berthe
Diplomsko delo
Oznake: diplomske naloge;visoko-trdnostne aluminijeve zlitine;površinsko utrjevanje s plastično deformacijo;lasersko udarno utrjevanje;zaostale napetosti;rentgenska difrakcija;
Izločevalno utrjene, visokotrdnostne aluminijeve (Al) zlitine so v industriji pomemben ter nepogrešljiv material predvsem zaradi dobrega razmerja med trdnostjo in gostoto. V letalski industriji so tako še vedno pogosto v uporabi, kljub velikemu porastu kompozitnih materialov z ogljikovimi vlakni, oj ...

This study investigates the microstructural, mechanical, high-cycle fatigue, and fracture behaviour of a dissimilar 2017A-T451/7075-T651 Al alloy joint produced by single-pass friction stir welding (FSW) without post-processing. Residual stress analysis revealed low tensile residual stresses in the ...

This paper presents an innovative methodology of material characterization under high strain rate (order of 10$^7$s$^{–1}$) laser shock loading coupled with microstructural and mechanical material features. To that scope, experimental and simulation analyses have been conducted for Al alloys (AA7075 ...
