Abstract

Studies in this research focus on understanding various elements such as alloying elements alongside heat treatment operations along with additive manufacturing parameters and environmental conditions that influence both mechanical properties and corrosion behavior of new alloy and composite materials. The experimental results show that nickel (Ni) proved to be the most effective alloying element because it resulted in maximum improvements to mechanical properties together with (Al) and (Mo). The mechanical properties received maximum improvement through heat treatments that included solution treatment followed by aging at 900°C. The combination of additive manufacturing process parameters which include layer thickness and laser power and scan speed directly controlled the tension strength and surface quality together with porosity in printed products. Material durability improved best from coated steel and then titanium alloys and stainless steel and aluminium through surface treatment methods. Moreover, regression analysis also brought out the profound influences of laser power, scan speed, heat treatment temperature, and cooling rate on ultimate tensile strength (UTS). Overall, the research emphasizes the significance of alloy composition, processing conditions, and manufacturing parameters in maximizing material performance for different engineering applications.
