Recycling's value in conserving scarce resources, avoiding environmental damage to the land, and reducing energy consumption is well known. This research aims develop a composite that uses recycled reinforcement was formed through an situ method build confidence usage of materials. Thus, connection with defense aerospace industry applications, aluminum alloys receive more interest due their light weight high strength improved mechanical properties; therefore, this focuses on fabrication situ-developed TiC (r-TiC)-reinforced AlZnMgCu composites, i.e., new Experiments were conducted determine synthesized composites' microstructural, mechanical, tribological, corrosion properties. The microstructural study showed r-TiC distributed uniformly along grain boundaries until addition 12% r-TiC. However, accumulation reinforcements began at 14% became aggregated subsequent increases percentage tribological tests superior all other compositions, 60% qualities lowest wear rate 0.0007 mm3/m. Composites containing 2% best resistance, increase 22% over AlZnMgCu, without reinforcement.

This study proposes an advanced space radiation shielding design method that integrates multi-objective optimization with reliability evaluation to mitigate the impact of harsh environments on electronic systems. A genetic algorithm is employed optimize multi-layer configurations respect dose reduction, mass efficiency, and structural thickness. To ensure practical applicability, a framework incorporating uncertainty factors developed, where designs are considered acceptable when risk confidence level (CL) remains below 5%. case simulating long-duration deep missions demonstrates optimized five-layer configuration reduces radiation-induced failure rate by approximately 57%, enhancing long-term core components 0.94 over five-year mission. These findings validate effectiveness proposed approach in supporting development reliable, lightweight for future missions.

Cu/Nb multilayer composites with a continuous layered structure were fabricated using accumulative roll bonding (ARB). The effects of Joule heating on the mechanical properties and fracture behavior these under electrically assisted tension (EAT) at different current densities investigated. It is observed that ultimate tensile strength (UTS) exhibits progressive decline increasing density. When density reaches 120 A/mm2, UTS decreases by 68.9 MPa, this tends to saturate high densities. Furthermore, elongation (EL) displays significant enhancement 40 A/mm2 80 particularly reaching maximum improvement 42.1% when compared room temperature (RT). mode during EAT process consistent RT, which remains ductile fracture.
