Effects of SiCp distribution on microstructure, mechanical properties and deformation behavior of SiCp/2024Al composites

Cailiao gongcheng
SiCp/2024Al composite was prepared by semi-solid stirring casting, and the distribution of SiCp was regulated by multi-step deformation of hot extrusion and multi-direction forging (MDF).

Influence of thermomechanical processing on coarse particles, grain structure, and mechanical properties of Al–Cu alloy rings

Journal of Materials Research and Technology, 2023
Rings made of 2219 Al alloy are typically manufactured by multi-directional forging (MDF) and ring rolling at 460 °C, followed by heat treatment. However, this process often results in coarse elongated grains and a large number of coarse Al2Cu particles,

So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]

, 2014
Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.

Crystallographic orientation and slip behavior of powder metallurgy Ti–6Al–4V via multi-directional forging

Journal of Materials Research and Technology
In this study, we present a microstructural and mechanical analysis of Ti–6Al–4V alloys processed by low-temperature multi-directional forging at 900 °C, achieving near-theoretical density (99.9%), with a tensile strength of 1070 MPa and elongation of 14.
