Development of Warm Forging Method for Magnesium Alloy * [PDF]
, 2020 A new warm forging method for magnesium alloys is proposed by taking their material properties into consideration. Since the ductility of Mg alloys is low at room temperature, the forging operation is conducted in the temperature range of 200-400 C.

In-Line Dimensional Inspection of Warm-Die Forged Revolution Workpieces Using 3D Mesh Reconstruction
Applied Sciences, 2019 Industrial dimensional assessment presents instances in which early control is exerted among “warm” (approx. 600 ∘C) pieces. Early control saves resources, as defective processes are timely stopped and corrected.

Development of Warm Forging Method for Magnesium Alloy
MATERIALS TRANSACTIONS, 2004 A new warm forging method for magnesium alloys is proposed by taking their material properties into consideration. Since the ductility of Mg alloys is low at room temperature, the forging operation is conducted in the temperature range of 200-400°C. In the warm forging of Mg alloys, the billet is easily cooled down in the die cavity before the onset of

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils
Advanced Science, EarlyView.We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet
