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.

Materials Basel. Hornbogen E. Mater Des ;—8. Int J Corros ; Rudnytskyj A. The accuracy of material parameters were verified on the comparison between indentation test and numerical simulation under different loads of 0. The micro-hardness test was carried out to obtain the hardness gradient curve along the LSS to the carbon steel side to investigate the mechanical properties of the composite region between different kinds of carbon steel and stainless steel. The interaction was divided into two periods: before indentation test and indentation test process; in the period of before indentation test, the bottom surface was selected as master surface of contact, the top surface of sample was selected as slave surface of contact. Thus, we want to establish a method to bridge the hardness and material parameters, so that we could obtain the material parameters by hardness test on the surface of engineering structures.

Visar Farhangi et al. Kyriakos I. Adv Mater Sci Eng ; IEEE E. The consideration is taken that surface hardness could be acquired easily using a hardness test. Nevertheless, the accurate mechanical parameters of materials are significant basic data for the integrity evaluation of actual engineering structures [ 4 , 5 , 6 ]. The yield strength and microhardness in each area of the composite region of clad rebar were obtained via linear fitting between the finite element numerical model and the indentation test: R p0. The indentation load was 9. The common dimension systems were as shown in Table 2. Mater Tehnol ;— Journal ;—5.
