Effect of tempering conditions on dynamic deformation behaviour of an aluminium–lithium alloy

State-of-practice on the mechanical properties of metals for armor-plating

“…During their study, they observed little difference in the amount of deformation between solid aluminum plates, aluminum plates containing small slits, and aluminum plates containing small, diamond-shaped notches. Ghosh et al (2015) studied the effect of natural and artificial aging on the dynamic compressive stress and strain of AA 2099. They found that artificial aging resulting from heating the samples at temperatures of 120-160°C for 12 to 18 hr caused an increase in the number of precipitates in the microstructure.…”

Effects on Texture and Microstructure of Aluminium Alloy 7075-T651 during High Strain Rate Torsion

“…The high strength to weight ratio of Al-Zn-Mg-Cu alloys can be attributed to interaction between mobile dislocations and finely dispersed precipitates [3]. However, these aircraft components are susceptible to dynamic impact loading in service, in which case strain rate of the order of ~10 3 s -1 can be achieved [4]. Such high strain rates can be achieved in the event of collision with flying debris or birds [4].…”

“…However, these aircraft components are susceptible to dynamic impact loading in service, in which case strain rate of the order of ~10 3 s -1 can be achieved [4]. Such high strain rates can be achieved in the event of collision with flying debris or birds [4]. Consequently, catastrophic failure can occur or can cause severe maintenance and repair costs.…”

Fracture analysis of high strain rate torsion samples of aluminium zinc magnesium copper alloy

“…10 The Torsional Split Hopkinson Bar has been widely used to test various materials including composites, aluminum, stainless steel, and the super alloy Inconel at elevated strain rates. [11][12][13][14][15] There is abundant literature available for high strain rate deformation under compression loading, while the same under torsion is scarce.…”
