Numerical modelling of the aluminium extrusion process [PDF]
The extrusion of aluminium alloys involves the shaping of the product from an homogenised billet into a complex shape. In addition the properties of the extrudate are closely related to the processing parameters (temperature, stain rate, and material ...

Study on serration flow and dynamic strain aging of Cr–Ti–B low-carbon steel
Journal of Materials Research and Technology, 2021 Compression tests were carried out for hot-rolled Cr–Ti–B low-carbon steels with different Cr contents (low Cr and high Cr) at three strain rates (0.01, 0.1 and 1 s−1) and temperatures ranging from 250 to 650 °C.

Study of Orientation of Triangular and Square die hole profiles on Extrusion Load in Multi-hole Extrusion process [PDF]
E3S Web of Conferences, 2023 The multi-hole extrusion process is an extrusion process with a die having more than one hole. The multi-hole extrusion process is used to extrude more than one product from the same billet with less extrusion load. Different die profiles are used to get

Numerical modelling of the aluminium extrusion process and comparison with results obtained from industrially extruded complex sections. [PDF]
This thesis reports the analysis of extruded products by Forge2009® and EBSD produced by the investigator in the BOAL plant. The 3D FEM module was used to study the required load, the temperature evolution, surface formation of the extrudate and material

Research on the Extrusion Process of belt with Notch Descrition [PDF]
MATEC Web of Conferences, 2022 The extrusion process of the belt is a process in which the belt and the inner bore of the barrel undergo complex contact and collision, and the rifling gradually penetrates the belt, so that the material of the belt continues to fail and destroy. It has

Preparation of Biodegradable Materials by Reactive Extrusion [PDF]
Materials Science Forum, 2008 This work aimed to prepare biodegradable polymeric materials based on blends of a synthetic high density polyethylene (HDPE) and biodegradable polymers such as polylactic acid (PCL) and poly(caprolactone) (PLA), in a co-rotating twin-screw extruder. A polyethylene modified with maleic anhydride was used as compatibiliser.
