Influence of choked angle of bearing channel on profile grain structure during multi-hole extrusion of aluminum alloy [PDF]

open access: yes, 2018
Direct extrusion of aluminum alloy EN AW-6060 was carried out applying a four-hole die with pair-wise parallel and choked long channels. Due to the dissimilar friction inside parallel and choked channels profiles with different length were extruded ...

MICROSTRUCTURE AND THERMAL STABILITY OF Al-Fe-X ALLOYS

open access: yesActa Metallurgica Slovaca, 2018
In this work, Al-11Fe, Al-7Fe-4Ni and Al-7Fe-4Cr (in wt. %) alloys were prepared by combination of casting and hot extrusion. Microstructures of as-cast alloys were composed of aluminium matrix with large and coarse intermetallics such as Al13Fe4 ...

Impact of experimental conditions on material response during forming of steel in semi-solid state [PDF]

open access: yes, 2010
Semi-solid forming is an effective near-net-shape forming process to produce components with complex geometry and in fewer forming steps. It benefits from the complex thixotropic behaviour of semi-solids.

Thermal exchange effects on steel thixoforming processes [PDF]

open access: yes, 2010
Steel thixoforging is an innovative semi-solid forming process. It allows the manufacturing of complex parts and minimises the forming load. This work aims to identify and characterise the main feature zones of a thixoforging part.

Controlled Grain Refinement of Biodegradable Zn-Mg Alloy: The Effect of Magnesium Alloying and Multi-Pass Hydrostatic Extrusion Preceded by Hot Extrusion

open access: yesMetallurgical and Materials Transactions. A, 2020
To satisfy the most stringent criteria in terms of new cardiovascular stents, pure Zn was alloyed with 1 wt pct of Mg and subsequently subjected to plastic deformation, using conventional hot extrusion followed by multi-pass hydrostatic extrusion.
