Summary: Through cold rolling deformation, the microstructure of P/M aluminum alloy gradually transforms, with reduced grain size, increased relative density, and enhanced tensile strength. The improved mechanical properties mainly result from the combined effects of increased microstructural compactness and deformation strengthening.

Summary: Powder metallurgy Cu-30Fe alloy was prepared using mechanical alloying, pressureless sintering, and rolling processes. The rolling process affected the alloy microstructure and physical properties. The Fe particles became elongated and changed shape, while the Cu grains became elongated and refined. The coordinated deformation of the Cu and Fe phases resulted in finer Cu grains near the Fe particles. After annealing, the cold-rolled Cu-30Fe alloy achieved a good combination of mechanical and functional properties.

Summary: The AA5052 with a gradient strain and microstructure was produced by the accumulative compression bonding process in this study. A gradient microstructure was observed in the fourth pass sample, with elongated grains in the soft layer and fine equiaxed grains in the hard layers due to dynamic recrystallization. The fourth pass sample exhibited a good combination of high strength and high ductility, showing a recovery of strain hardening rate phenomenon with a remarkable improvement in strength.

Summary: Selective laser melting (SLM) of Al-3.48Cu-2.03Si-0.48Sc-0.28Zr alloy was systematically investigated in this work, showcasing a strong correlation between specimen density and laser parameters, along with the influence of laser energy input on pore formation and initiation of microcracks. The microstructure of the printed specimen exhibited grain refinement and lattice distortion, leading to increased tensile strength and elongation. This study provides valuable insights for designing high strength-ductility aluminum alloys for SLM.

Summary: Investigations were conducted on the rolling modes of plates made from an experimental aluminum-magnesium alloy with a scandium content of 0.10-0.11 wt.%. It was found that alloying with scandium significantly improved the grain refinement and strength properties of the semi-finished products. Rational reduction modes were proposed based on physical and computer modeling, allowing for the production of deformed semi-finished products with the desired mechanical properties. The findings also revealed that annealing had minimal effect on the mechanical properties, while cold rolling resulted in increased strength.

Summary: The study investigated the effects of Ti powder addition and T6 heat treatment on the microstructure and mechanical properties of A356-based composites. It was found that the addition of Ti led to changes in silicon nucleation, size, and porosity, with the T6 heat treatment transforming the eutectic Si structure. The composite with 0.5 wt% Ti showed the highest ultimate tensile strength among all samples, with improvements in hardness and tensile strength compared to the A356 alloy attributed to the presence of Ti and Al3Ti phases. The fracture surface of the A356/Ti composites was mainly covered by cleavage features.

Summary: The study showed that introducing Al3Er particles can improve the ultimate tensile strength and ductility of AA5056 alloy, while achieving a more uniform distribution of particles. Rolling the alloy results in a more uniform distribution of particles in the material, but does not increase its yield strength or ultimate tensile strength.
