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.

The indentation head was treated as a rigid body. The material chemical composition and the micro-hardness were both changed, which made it difficult to determine the material properties in each sub-region of the composite region [ 26 ]. Furthermore, a linear relationship was discovered between hardness and yield strength through the experiment of the SODH metal layer. Hence, the relationship between Richter hardness and yield strength was established and a method of moderate damage detection was proposed to acquire the parameters of the steel bar in service which was superior to the tensile test. Xue H. Therefore, it is of great importance to acknowledge the mechanical property parameters of the composite region in the structural integrity evaluation of clad rebar. The structures of steel are significant parts of infrastructures. Dahle AK, Arnberg L. Determination of the critical fraction of solid during the solidification of a PM-cast aluminium alloy. Introduction The structures of steel are significant parts of infrastructures. Year Volume: 7 Issue: 1. A bright-field TEM was used to observe that the striped martensite structure was produced on the side of the austenitic stainless steel, according to Li Zhen et al. Feng Y. The process effectively solved the interface oxidation problem of billet during heating and rolling, however, the production cost was high. The experimental data are shown in detail in Table 5.

Rail Rapid Transit. The material chemical composition and the micro-hardness were both changed, which made it difficult to determine the material properties in each sub-region of the composite region [ 26 ]. Furthermore, the hardness of FEM and a physical test were well-fitted. Table 4 Indentation diagonal length of numerical simulation under different yield stress. Lim D. Abstract Clad rebar is one of the key structures of marine and construction services. Materials and Experimental Method 3. Andre Rudnytskyj et al. Regarding the hardening index, the relations are as follows [ 24 ]:. Metall Mater Trans A ;— Figure 9. The contact property was tangential behavior, the friction formulation was penalty, the directionality was isotropic and the friction coefficient was 0. The experimental data are shown in detail in Table 5.
