Effect of temperature and drawing speed on warm deep drawing characteristics of AZ31 magnesium alloy sheet

Journal of Japan Institute of Light Metals, 2006
In this study, effect of drawing speed and flange temperature on formability of cylindrical cup warm deep drawing of AZ31 magnesium alloy sheet is clarified experimentally. For the purpose, a new locally heating and cooling deep drawing apparatus is designed and developed. Magnesium alloy used is AZ31 sheet with 0.5mm thickness.

Investigation on the optimal geometrical parameters for cylindrical cups in warm hydromechanical deep drawing process

2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017
Warm sheet hydroforming process has being investigated in recent years with its high formability feature. Warm hydromechanical deep drawing (WHDD) which is a type of the warm sheet hydroforming process is important for deeper parts. To determine the formability of the WHDD process the most convenient tool is Limiting Drawing Ratio (LDR).

Circular and square cups drawing and ironing of Ti alloy sheets by incremental press forming method [PDF]

MATEC Web of Conferences
The low ductility of Ti–6Al–4V alloy at forming temperatures below 780°C is still a problem. Ti–6Al–IV alloy is usually hot press formed at 780 to 900°C.

Experimental research on warm deep drawing of HC420LA grade sheet material

The International Journal of Advanced Manufacturing Technology, 2016
The use of high-strength sheet material applications in the automotive industry has become widespread due to their high strength/weight ratios. The formability, however, of these high-strength sheet materials is limited at room temperatures (RTs).

Comparison of the Mechanical Properties and Forming Behavior of Two Texture-Weakened Mg-Sheet Alloys Produced by Twin Roll Casting

Frontiers in Materials, 2019
The influence of rolling and annealing on the resulting mechanical properties and forming behavior of Mg-Zn-RE and Mg-Zn-Ca alloys produced via twin roll casting is investigated. After hot rolling followed by an annealing treatment, both alloys develop a

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
