The general principles behind the global mechanical tensioning technique for controlling weld residual stresses are examined using a finite lement model to follow their evolution throughout the welding process. While we focus specifically on friction stir welding, the tool is represented imply as a heat source. As a result, the findings have relevance to a wide range of welding processes. For a...

Compared to the recycling process by remelting, hot extrusion significantly reduces energy consumption and CO2 emission ensures good mechanical microstructural properties. This study investigates effects of reinforcing aluminium AA6061 chips with mixed boron carbide (B4C) zirconia (ZrO2) particles employing a design experiment (DOE) under 550 °C processing temperature three hours preheating tim...

The ESS-Bilbao facility, hosted by the University of the Basque Country (UPV/EHU), envisages the operation of a high-current proton accelerator delivering beams with energies up to 50 MeV. The timeaveraged proton current will be 2.25 mA, delivered by 1.5 ms proton pulses with a repetition rate of 20 Hz. This beam will feed a neutron source based upon the Be (p,n) reaction, which will enable the...

Aluminum alloy has been widely used due to its excellent workability, and double-pulse metal inert gas welding (MIG) become a popular technique in aluminum welding. In this study, cross-complementary test was performed study the effect of characteristics on weld bead formation mechanical properties MIG The carried out an AA6061 using flat overlaying After welding, micro-metallographic structure...

Aluminum alloy (AA6061)-based hybrid metal matrix composites (HMMCs) are manufactured using a dual stir casting method, with varying volume percentages of B4C (5%, 10%, and 15%) Gr (10%, 15%, 20%) incorporated. The resulting HMMC reinforcement elements uniformly dispersed within the main matrix, forming mechanically mixed layer interfacial reactions. This reduces wear loss friction coefficient ...
