TL;DR: In this paper, the authors proposed an optimum process design system to assist the decision of material process condition for making a sheet metal which has better formability for stamping, which is realized by combining finite element analysis and discretized optimization algorithms.

TL;DR: In this paper, a vibration damper is formed from two metal layers, one with primer layers, slit, and partially stamped to form a strip holding a plurality of vibration dampers, each of which has a body portion and tab portions.
Abstract: A vibration damper is formed from two metal layers. The first metal layer is coated with primer layers, slit, and partially stamped to form a strip holding a plurality of vibration damper blanks. Each of these blanks has a body portion and tab portions. A second metal layer is formed separately by coating a second metal strip with adhesive and stamping it to form a plurality of vibration damper blanks but without tabs. The two strips are aligned, bonded together and the vibration dampers are formed and stamped out. (The tabs, which are only on one layer, are bent to form clips.) Due to this construction the clips cannot delaminate and provide a noiseless metal contact with the shoe plate, while an improved adhesive can be employed to bond the two metal layers together.

TL;DR: The deformability of PDMS stamp is focused on and an appropriate stamping force in micro-contact printing is discussed, which would provide a high-quality ECM pattern and a breakthrough technique to fabricate multi-cellular-patterned cell sheets for the next generation of regenerative medicine and tissue engineering.

TL;DR: In this article, it was observed that the tempering treatment on the directly hot-stamped boron steel resulted in better mechanical properties and higher formability index compared with the reported results using the Q&P process.
Abstract: The hot stamping process has an extensive range of applications due to its advantages over the traditionally used stamping techniques developed in the past. To enhance the mechanical properties of the indirectly hot-stamped parts, the quenching and partitioning (Q&P) process has been recently applied on boron-alloyed steel. In the current research, it was observed that the tempering treatment on the directly hot-stamped boron steel resulted in better mechanical properties and higher formability index compared with the reported results using the Q&P process. The nano-carbide formation and the dislocation annihilation during the tempering treatment were suggested as the evident reasons for the occurrence of the mentioned robust properties. The ease of the practical implementation of the tempering route together with the markedly enhanced mechanical properties of the tempered parts make the suggested method privileged. Additionally, the variations in the yield strength before and after tempering were quantitatively evaluated.

TL;DR: In this paper, the behavior of the steel grade MSW1200 blanks under semi and fully hot stamping processes was characterized and it was concluded that semi-hot stamping process could be considered as an improved thermo-mechanical process which not only guaranteed a high formability, but also led to ultra high strength values.
