In this paper, the microstructure and material properties of continuous cast 5052 alloy sheet in as-received condition (as-received sheet) and laboratory cold rolled condition (lab-processed sheet) were investigated after annealing treatment.Abstract:
The microstructure and material properties of continuous cast 5052 alloy sheet in as-received condition (as-received sheet) and laboratory cold rolled condition (lab-processed sheet) were investigated after annealing treatment. Microstructural examinations show that the cold rolling process increases the extent of centerline segregation of second-phase particles. The increase in rolling reduction results in a decrease of grain size and a more random distribution of crystallite orientations. Tensile test results indicate that all the sheets exhibit two-stage strain-hardening behavior. Cold rolling increases the total elongation and n2-value in the transverse direction of the lab-processed sheet with a thickness of 1.6 mm. However, further increase in the rolling reduction leads to an increase of UTS with a decrease of elongation and n2-value. Furthermore, from the determined forming limit curves (FLCs), it is found that the 1.6 mm thick lab-processed sheet has better stretchability than the as-received sheet, whereas further cold rolling reduces the level of FLC. The effects of cold rolling on the mechanical property and formability are discussed in terms of the microstructural changes.read more

Asymmetric mechanical properties and tensile behaviour prediction of aluminium alloy 5083 friction stir welding joints
TL;DR: In this article, micro-tensile and indentation testing were applied to determine the local mechanical properties in a friction stir welded joint, and the local stress-strain curves exhibited a drastic change at the advancing side (AS) due to a steep gradient of mechanical properties.

On the mechanical behavior of cold deformed aluminum 7075 alloy at elevated temperatures
TL;DR: In this paper, the effects of deformation parameters on the mechanical behavior of 7075 aluminum alloy at annealed and cold rolled conditions were examined. And the results showed that high temperature flow was noticeably strain rate sensitive especially for the rolled condition, while cold work was shown to have a remarkable influence on increasing the peak stress up to 250°C.

A general forming limit criterion for sheet metal forming
TL;DR: In this article, it is shown that the forming limit for both proportional loading and non-proportional loading can be explained from a single criterion which is based on the state of stress rather than the state-of-stress.
