In this study, the effect of Al5Ti1B grain refiners and Al10Sr modifiers on the mechanical and corrosion properties of the A aluminum alloy was investigated. For this purpose, varying amounts of Al5Ti1B grain refiner and Al10Sr modifier were added to the molten A alloy and the molten metal was poured into a per-manent mold. Subsequently, microstructural investigations, hardness test, tensile strength and corrosion resistance of the samples were examined. The results showed that, the Al5Ti1B grain refiner promotes finer-grained and coaxial solidifi-cation. The Al10Sr modifier, broke down the eutectic particles in the microstruc-ture and caused a more homogeneous distribution in the structure. While the tensile strength and corrosion resistance of the alloy increased both the grain refiner and the modifier added to the A alloy, a slight decrease in hardness was observed in the alloys to which only the modifier was added.

Combining hardness measurements of a heat-treated crankshaft bearing with cross-sectional residual stress and retained austenite distributions measured by HEXRD. The sample of FEM was as shown in Figure 6 a, the mesh refinement was as shown in Figure 6 b, and the assembly was as shown in Figure 6 c. Sci Prog ; Ramberg W. Zhen Li et al. Author Contributions Conceptualization, Z. Keywords: clad rebar, composite region, structural integrity assessment, hardness, yield strength. Rail Rapid Transit. Kyriakos I. The mechanical property parameters are acquired; moreover, the relationship between yield stress and surface hardness of the stainless steel clad rebar is set up. Theoretical Basis Austenitic stainless steel and carbon steel are widely used in construction structures, due to their good mechanical behaviors of strength toughness and corrosion resistance.
