Even when casting has not been adopted to generate the shape of a component it may well have entered into the process of manufacture at an earlier state having been used to produce the stock for mechanical working, forging, rolling or extrusion by a process such as ‘ingqt’, ‘billet’,...
The importance of actin dynamics in the control of secretory granules extrusion is now well established30,31,40–42. Actin was initially thought to be entirely cleared from the synaptic area. It was therefore proposed that actin acts as a barrier preventing granules to reach the plasma membrane....
This chapter provides an overview of the common types of defects found in various structural materials and joints in aircraft. Materials manufacturing methods (including large-scale production) have been established in the aircraft industry. However, as will be seen in this chapter, manufacturing defec...
Additive friction stir deposition (AFSD) is a solid-state additive manufacturing (AM) process in which material is added layer-by-layer to form a part, based on its CAD model. Unlike fusion-based AM processes such as powder bed fusion (PBF) [1] or directed energy deposition (DED) [2],...
Fig. 6. Process-, product-, or people-centricity. Again, there appears to be an abundance of ZDM research that focusses on manufacturing processes (e.g., process monitoring, process control, process parameters, etc.). This has been a common theme in the ZDM literature throughout the previo...

This illustrates that the intensive melt shearing produces a uniform equiaxed grain structure throughout the billet providing a microstructure that is more suited for further processing via extrusion or forging processes. The melt conditioned billet in turn shows more uniform chemical composition from the...
bone resorption, and through direct cell-to-cell contact, absorption of old bone resulting in the release of growth factors and secretion of a series of coupling factors, it promotes the recruitment, proliferation, and differentiation of osteoprogenitor cell, thereby coupling the osteogenic process. ...
detecting a surface defect of a round wire rod in real-time and without contact. The device and method can detect the surface defect using an optical sensor, in which the surface defect occurs on the wire rod in a process of manufacturing the wire rod through rolling, drawing and extrusion...
