“…Their research results showed that size effects were noticeable and significant when the thickness of the foils was equal to or less than 100 µm, and foil thickness, grain size and ratio of foil thickness (T) to grain size (D) affected significantly the value of LDR of ASS 304 foils. Ma et al [10] established a numerical model to investigate the MDD with radial pressure, and found that appropriate radial pressure and gap distance could improve the LDR of drawn ASS 304 circular cups by reducing the friction resistance. Huang et al [11] investigated the MDD with assistance of ultrasonic vibration.…”

In the present work, austenitic stainless steel (ASS) 304 foils with a thickness of 50 µm were first annealed at temperatures ranging from 700 to 1100 ℃ for 1 h to obtain different microstructural characteristics. Then the effects of microstructural characteristics on the formability of ASS 304 foils and the quality of drawn cups using micro deep drawing (MDD) were studied, and the mechanism involved was discussed. The results show that the as-received ASS 304 foil has a poor formability and cannot be used to form a cup using MDD. Serious wrinkling problem occurs on the drawn cup, and the height profile distribution on the mouth and the symmetry of the drawn cup is quite non-uniform when the annealing temperature is 700 ℃. At annealing temperatures of 900 and 950 ℃, the drawn cups are both characterized with very few wrinkles, and the distribution of height profile, symmetry and mouth thickness are uniform on the mouths of the drawn cups. The wrinkling becomes increasingly significant with a further increase of annealing temperature from 950 to 1100 ℃. The optimal annealing temperatures obtained in this study are 900 and 950 ℃ for reducing the generation of wrinkling, and therefore improving the quality of drawn cups. With non-optimized microstructure, the distribution of the compressive stress in the circumferential direction of the drawn foils becomes inhomogeneous, which is thought to be the cause of the occurrence of localized deformation till wrinkling during MDD.

With the advantages of high utilization of raw materials, high precision and low cost, micro metallic parts produced by micro deep drawing (MDD) have been tremendously used in a variety of fields such as micro-electromechanical systems (MEMS), vehicle engineering and chemical engineering. In order to study the deformation behavior of two-layer stainless steel-copper composite foils during MDD, a series of MDD tests were performed with specimens annealed at temperatures ranging from 600 to 1000 °C. The results show that complete circular cups cannot be formed using the as-received material due to its poor formability. For the specimens annealed at 600 and 700 °C, significant wrinkling is observed on the drawn cups. Differently, few wrinkles are characterized on the drawn cups when the composite foils are annealed at temperatures ranging from 800 to 1000 °C. An optimal annealing temperature of 800 °C is obtained for the MDD of stainless steel-copper composite cups with high surface quality.
