PERBANDINGAN PERLAKUAN T6 DAN TEMPERING CASE HARDENING ALUMINIUM 7075 TERHADAP SIFAT MEKANIK

Ionic Inhibition of Environmental Fatigue Crack Growth in 7075-t6

The objective of this study is to quantify and understand the effectiveness of a hexavalent chrome replacement ion to inhibit environmentally assisted fatigue crack propagation (EFCP) in high strength aluminum alloys. Because of dynamic-cyclic stress (or strain) loading, fatigue degradation occurs at stress levels considerably lower than the tensile or yield strength; degradation is exacerbated...

تضعیف امواج آکوستیک در Al 7075-T6 و St 304

Propagation and dispersion of acoustic waves is one of the important phenomena in physics. Acoustic-waves are nowadays widely used in a variety of applications ranging from underwater communications, identification and specification of the internal defects of materials to extracorporeal shock wave lithotripsy. Apart from application and utilization of such phenomena, study on production and pro...

Strengthening Mechanisms in the Aged 2024 and 7075 Aluminium Alloys

Aluminum 2024 and 7075 alloys which are widely used in aerospace and marine applications were chosen to investigate their strengthening mechanisms. Using differential thermal analysis (DIA), metallography and tension tests, the best solutionizing conditions were determined to be 500±5°C and 2 hours for 2024 and 480?±5°C and 1 hour for 7075 alloy. Aging was performed in the range of 100 to 200°C...

Aluminium Nanowires: Influence of Work Hardening on Conductance Histograms

Modelling of Precipitation Hardening in Casting Aluminium Alloys

Precipitation hardening, because it involves the hardening of the material over a prolonged time, is also called age hardening, or ageing. By the appropriate heat treatment of precipitation hardening, the strength or hardness of some heat-treatable aluminium alloys can be enhanced by the formation of nano-meter sized second-phase precipitated particles within the original phase matrix. The fine...
