“…The Cluster (1) structure had a wider range of Mg/Si ratios and was nearly insoluble at heat treatment temperature (180-200 • C). Cluster (2) could form above 100 • C, suppressing the formation of Cluster (1) during room temperature storage, and over-saturated vacancies inhibited natural aging, thus inhibiting the formation of Cluster (1). Cluster (2) had a Mg/Si ratio similar to the β ′′ phase, facilitating the formation of the β ′′ phase during the heat treatment process.…”

“…Among various aluminum alloy hot stamping techniques, Hot Forming-Quenching (HFQ) technology has gained significant attention. This technology involves rapidly transferring a fully solutionized aluminum alloy onto a cold die, promptly closing the die, and achieving in-die quenching [1]. In a study conducted by Omer [2] et al, the influence of the HFQ process on the mechanical properties of AA5754 was investigated.…”

This study explored the impact of Hot Forming–Quenching (HFQ) and heat treatment processes on the mechanical properties of AA6016 sheets. The experimental findings demonstrated that at high-temperature pre-straining (HT-PS) of 15%, the strength performance of the AA6016 sheet exhibited enhancement, with a progressive increase in both the heat treatment temperature and duration. Conversely, under HT-PS conditions of 3% and 7%, the heat treatment process exhibited a relatively modest impact on the mechanical properties of the AA6016 sheet. Differential scanning calorimetry (DSC) was employed to understand the influence of different process conditions on the precipitated phases. By comparing the precipitation peaks of the β″ phase at HT-PS of 3% and 15%, it was observed that the precipitation peak of the β″ phase decreased with an increase in HT-PS. This indicated that HT-PS promoted the precipitation of the β″ phase. In order to forecast the mechanical performance of the AA6016 sheets after applying various pre-straining and heat treatment parameters, two models were used: a backpropagation (BP) neural network and a genetic algorithm (GA)-BP neural network. These models were evaluated for their fitting and predictive capabilities. The research findings demonstrated that the GA-BP neural network model exhibited superior fitting and predictive accuracy compared to the BP neural network model.

“…Forming in as-quenched temper (W-temper) provides good formability and reduced process times. Zhang et al tested the hot form and quench process in O-temper at room temperature before solution heat treatment and ageing and found that ductility/formability and strength potential were both significantly reduced compared with the original hot form and quench process [3]. Zheng et al found that the deformation characteristics and post-form strength of heat-treatable aluminum alloys were significantly dependent on temper and forming processes [4].…”

Hot deformation and in-die quenching of aluminum components for the automotive industry is a cost and energy efficient technique that has been developed and thoroughly evaluated in recent years. The performance of this process is considered higher when compared to traditional cold metal forming due to shorter process times, low-cost machinery, and a high level of structural integrity in fabricated parts. The work presented in this paper provides several approaches for the formability of age hardenable 6xxx alloy sheets when forming at different temperatures. Warm tensile testing and formability cup testing were carried out to investigate the alloy formability at different temperatures. The results indicate that the formability of candidate alloys is not significantly affected by deformation temperatures or conditions, which provides great freedom when designing an automated production process with high productivity and minimal environmental impact. The candidate alloy can be deep drawn without severe thinning at the whole temperature range, from room temperature (RT) to solutionizing temperature.
