Summary: The design of high-performance overhead aluminum wires is challenging due to the trade-off between strength-ductility and strength-electrical conductivity. In this study, in-situ halide salt reactions were used to introduce dual-size TiB2 particles into 6201 alloy, resulting in improved mechanical properties with slight sacrifice of electrical conductivity. The addition of Al-3B master alloy successfully optimized the electrical conductivity, as well as maximizing the strength and ductility.

Summary: Heterogeneous B4C/Al composites with soft and hard zones (SZs and HZs) were fabricated using a combination of segmented ball milling and pressure infiltration. The width of the SZs could be controlled by adjusting the parameters of the ball milling process. The mechanical incompatibility between the SZs and HZs led to the accumulation of dislocations near the interface and the formation of non-interface-affected zones (NIAZ). Reducing the width of the NIAZ improved the strength of the material. Additionally, the uniform distribution of plastic strain and other toughening mechanisms contributed to the enhancement of ductility.

Summary: In this study, (TiB + TiC)/Ti6Al4V composites (TMCs) were prepared using in situ synthesis technology and hot indirect extrusion was conducted at four different temperatures. It was found that below the phase transition temperature, mechanical effects significantly influenced the microstructures of TMCs, leading to the formation of more elongated α grains. The yield strength decreased gradually with increasing extrusion temperature, while elongation initially increased and then decreased slightly.

Summary: This study investigated the microstructures, mechanical properties, and strain hardening properties of 1 vol% and 2 vol% (Al3Zr/Al2O3 + ZrB2) nanoparticles reinforced 6016Al matrix composites, which were synthesized through in-situ chemical reaction and solidified under squeezing pressure. It was found that Fe-B-rich and AlB2 phase particles were also formed in addition to the reinforcement particles. The matrix of the 1 vol%-6016Al composite exhibited fine Mg2Si precipitates under high squeezing pressure, while the matrix of the 2 vol%-6016Al composite did not show such precipitates. The squeezed 1 vol%-6016Al composite also had a greater reduction in grain size compared to the squeezed 2 vol%-6016Al composite. The squeezed 6016Al matrix composites exhibited high strength, high ductility, and lower strain hardening effect in the aged state, which was different from monolithic 6016Al alloys.

Summary: Magnesium matrix composites (MMCs) have shown promising mechanical properties at both room and elevated temperatures. The commonly used ceramic particle reinforcements often improve the yield and ultimate stresses but sacrifice ductility. Titanium (Ti) has been introduced as an alternative reinforcement due to its high melting point, high Young's modulus, high plasticity, low mutual solubility with Mg matrix, and similar thermal expansion coefficient. However, challenges remain in achieving Ti's homogeneity, high recovery rate, and optimizing the interfacial bonding strength between Mg and Ti in MMCs. This review focuses on the microstructural characteristics, mechanical properties, and fabrication techniques of Ti-reinforced MMCs, comparing and discussing the influencing factors that govern the strengthening mechanisms.

Summary: In this study, the morphologies of AlP crystals were comprehensively studied, revealing two categories of AlP crystals and their morphological templated nucleation of primary Si phase. This process increased the percentage of primary Si twin crystals in the alloy and eliminated dendritic growth and hopper structures inside primary Si, maintaining faceted solid crystals through layer-by-layer growth mechanism. The insight into morphologically templated nucleation provides a new perspective on the mechanism of heterogeneous nucleation of primary Si phase on AlP nuclei.

Summary: This study investigates the effects of fibre concentration on the mechanical response of welded glass-fibre-reinforced polypropylene (GF-PP). Experimental observations reveal a significant reduction in weld ratio, up to 60%, indicating a decreased strength compared to the bulk material. Increasing fibre content in the welded material results in a decrease in stress at break and strain at the maximum stress. The use of DIC technique and X-ray microtomography further confirms the localized strain amplification in the welded zone due to the significant increase in fibre density.
