Researchers investigated the optimization of self-healing concrete (SHC) properties by employing metaheuristic techniques alongside response surface methodology (RSM). They explored gray wolf optimization (GWO), multi-verse optimization (MVO), moth fly optimization (MFO), particle swarm optimization (PSO), and whale optimization algorithm (WOA) to predict mechanical properties based on bacteria concentration.

BU engineering doctoral student Sanika D. Barve is studying the mechanics of head carrying, and how fabric rings help people bear heavier loads.

Alumina-forming austenitic (AFA) steel, a promising candidate for use in high-temperature components of ultra-supercritical power plants, has high creep strengths and outstanding high-temperature corrosion resistance. The effects of microstructural evolution on the mechanical properties of Fe-20Ni-14Cr-3Al alumina-forming austenitic (3Al-AFA) steel with micro-cold deformation were investigated by multiple characterization methods, and the micro-cold deformation process was analyzed by conducting...

Cryogenic treatment enhances steel's mechanical properties by exposing it to extremely low temperatures, improving wear resistance and hardness.

Recent investigations have indicated that compositional heterogeneity, which is compositional undulation of alloying elements in single-phase solid solutions, can enhance the strength without sacrificing ductility, similar to cluster strengthening, of single-crystal nano-pillars and bulk nanocrystalline metallic materials. However, the impact of compositional heterogeneity on the mechanical properties of coarse-grained metallic materials is not yet fully understood. In this study, we examine the...

Multi-material components featuring high performance and design flexibility have attracted considerable attention, providing solutions to meet the performance demands of high-end equipment components. Achieving material diversity in additive manufacturing (AM) is a fundamental step towards manufacturing multi-material components. Wire arc additive manufacturing (WAAM), an important branch of AM technology, boasts notable advantages in the efficient and customized preparation of large-scale parts...

Metal composites have attracted many interests due to their multi-functionality and excellent overall performance. Medium Mn steels have received much attention as the third-generation high strength steels owing to the good balance between the low material cost and the excellent anti-wear and mechanical properties. Low carbon steels can provide required mechanical properties as base materials at a relatively low cost. In this study, microstructure and mechanical properties of low carbon steel (S...

It is common to use heat treatment process to control the microstructure of additive manufacturing parts and improve the mechanical properties. However, there are few reports about the control of microstructure properties of WAAM hybrid inter-layer hammering fabricated parts by heat treatment. In this study, the effect of annealing on microstructure and mechanical properties of inter-layer hammering hybrid wire arc additively manufactured aluminum alloy was studied. The ratio variation of fine g...
