AISI 630 alloy is widely used in the manufacture of CFM56 series aeroengine fan casing because of its high strength and excellent ductility. Herein, AISI 630 alloy is directly manufactured by directed energy deposition. The microstructural evolution, mechanical properties, and fracture behavior of AISI 630 alloy in as‐deposition, solution, and aging conditions are analyzed. Scanning electron microscopy, X‐ray diffraction, and electron backscattering diffraction are used to characterize the microstructure and phase characteristics. Mechanical tensile and Vickers hardness tests are performed. The results show that the samples as‐deposited, solution, and solution and aging samples are all composed of α phase and small amount γ phase, where γ phase proportions are 10.6%, 0.2%, and 10.8%, respectively. Due to transformation‐induced plasticity effect, the as‐deposited specimens have the highest strain hardening coefficient (0.410–0.432), which results in the tensile strength of 1121–1143 MPa, the yield strength of 279–293 MPa, and the fracture elongation of 14.9%. After solution and aging treatment, the tensile strength is increased by about 8% (1206–1239 MPa), the elongation at break is decreased by about 30% (9.6–11.4%), and the yield strength is increased by more than one time (740–907 MPa).

The aluminum metal matrix composites were broadly exploited in the applications of automotive, aerospace, and other defense with functionally graded materials-related application. Above applications definitely required excellent mechanical characteristics. Therefore, in this way, the major attempt was made on the nano-based composites with aluminum alloy utilization. In this research, aluminum alloy AA8011 and the ceramic-based reinforcement particles of nano boron carbide (B4C) were selected for producing the metal matrix composites by the liquefying process or stir casting route. The weight percentage of nano boron carbide particles having 15 wt% was subjected to add into the aluminum alloy during the stir casting process. Then, processed nano boron carbide and AA8011 specimens were prepared to conduct tribological behaviors with various processing conditions like sliding velocity, setting wear temperature, and applied load by the tribometer setup. The scanning electron microscope was employed to examine the processed composites samples and worn-out surface samples. Finally, the multiobjective optimization was used to measure the individual performances of the tribological parameters by the gray relational technique.
