Unprece dente d age-hardening and its structural requirement in a severely deformed Al-Cu-Mg alloy

Ran Yang et al.

Summary: A gradient nanostructured surface layer was produced in an Al-Cu-Mg alloy through surface sliding friction treatment at liquid nitrogen temperature, achieving unprecedented age-hardening after aging treatment with microhardness values exceeding previous maximum values. Enhanced grain boundary segregation instead of precipitation is believed to be responsible for this substantial age-hardening.

On the low-cycle fatigue behavior of thermo-mechanically processed high-strength aluminum alloys

S. V. Sajadifar et al.

Summary: This study evaluated the mechanical properties of thermo-mechanically processed AA6082 and AA7075 sheets under cyclic loading through low-cycle fatigue experiments. Different cooling rates resulted in precipitates with varying sizes and morphologies. The specimens processed in tools with temperatures of 24°C and 200°C exhibited superior mechanical properties, while different behavior was observed for the specimens formed in the tool with a temperature of 350°C. Thorough analysis of microstructural features revealed the significant impact of thermal history on the final performance of high-strength aluminum alloys.

Influence of post-heat treatment on the microstructure and mechanical properties of Al-Cu-Mg-Zr alloy manufactured by selective laser melting

Yanfang Wang et al.

Summary: A direct aging regime was proposed to maintain the grain-boundary strengthening and precipitation strengthening in modified conventional wrought aluminum alloys, resulting in a higher yield strength compared to the normal T6 heat treatment. The direct aging treatment preserved the ultrafine grains and precipitated spherical L1(2)-Al3Zr particles, while the solution treatment and aging led to grain coarsening and the presence of coarsening L1(2)-Al3Zr particles, nano-sized S' phases, and GPB zones. Both the direct aging and solution treatment and aging samples exhibited higher strength than other SLMed Al-Cu-Mg series alloys, comparable to the wrought AA2024-T6 alloy.

Fatigue and dynamic aging behavior of a high strength Al-5024 alloy fabricated by laser powder bed fusion additive manufacturing

Peidong He et al.

Summary: A high strength Al-5024 alloy with a bi-modal microstructure was successfully fabricated using laser powder bed fusion (LPBF) additive manufacturing. Different heat treatments showed a trade-off trend between yield strength and ductility, as well as a correlation between fatigue life and yield strength. Dynamic strain aging was found to occur in both as-built and some heat treated samples, attributed to magnesium solute atom clustering during subsequent heat treatments.

Experimental investigation of the damage characteristics of two cast aluminium alloys: Part III-Influence of the local microstructure and initial defect size on the fatigue properties

Carl Fischer et al.

Summary: The paper investigates the influence of locally varying microstructures in an AlSi12 cast aluminium alloy through extracting test pieces from different removal positions and conducting low cycle fatigue tests. It studies the temperature-dependent damage mechanisms, material specific defect types, sizes and their impact on fatigue properties of AlSi7 and AlSi12 cast aluminium alloys. An extreme value statistics methodology is applied to predict maximum defect sizes from metallographic micrographs, presenting a damage map for the AlSi12 cast aluminium alloy and explaining the influence of temperature- and load-dependent damage mechanisms on observed lifetime behavior.

Fatigue performance rejuvenation of corroded 7075-T651 aluminum alloy through ultrasonic nanocrystal surface modification

Ruixia Zhang et al.

Summary: The study showed that the fatigue performance of pre-corroded 7075-T651 aluminum alloy can be rejuvenated through ultrasonic nanocrystal surface modification (UNSM), increasing the fatigue life by twenty times compared to corroded specimens. This improvement is attributed to the repair of the corroded surface layer, surface workhardening, and beneficial compressive residual stress induced by UNSM.

Uncovering the origin of enhanced strengthening in Li-added Al-Cu-Mg alloys

S. Y. Duan et al.

Summary: The addition of 0.5 wt% Li to an Al-Cu-Mg alloy results in significant strength increases without sacrificing ductility, mainly due to modified precipitation behavior. The strengthening sources in unstretched and stretched alloys are fundamentally different, with Li favoring a high density of GPB zones in unstretched alloys and refined S-phase precipitates in stretched alloys. These modified precipitates with Li enrichments elucidate the strengthening origin in Li-added Al-Cu-Mg alloys under various conditions.

Effects of deformation temperature on second-phase particles and mechanical properties of multidirectionally-forged 2A14 aluminum alloy

Bingxiang Wang et al.

Summary: By subjecting age-hardenable 2A14 aluminum alloy to multidirectional forging at different temperatures, the mechanical properties were enhanced, with the best results obtained at an MD-forging temperature of 480 degrees C. Lower temperature MD forging led to network distribution of particles, causing stress concentration and crack initiation, resulting in decreased mechanical properties.

L. Mei et al.

Summary: The research found that the warm rolled alloy showed significant improvement in strength and corrosion resistance after appropriate aging, with good ductility. This improvement was mainly attributed to a more homogeneous distribution of nanosized precipitates in the grain interior and the absence of continuous grain boundary precipitates.
