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.

Brencich A. It was qualified that the hardness decreased with the fall in temperature. Kourousis I. This model can be further considered as a part of a comprehensive prediction model for estimating the stress—strain behavior of steel bars. The experiment loads were applied on 0. There are 46 citations in total. We used this method to acquire the mechanical parameters of a composite surface uneven area of clad rebar, and we established a mechanical parameters mathematics model of clad rebar, it is a significant basis for a structural integrity evaluation of cladding materials. Hao F. Moreover, the hardness decreased on account of the residual stress influence on the aluminum alloy T4 cladding zone. Warmuzek M. The FEM results, under different indentation loads where the yield stress of the material was MPa are shown in Figure 9. Mater Res Express ;7. References 1. 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 ]. Introduction The structures of steel are significant parts of infrastructures.

Effect of TiB2 and Al3Ti on the microstructure, mechanical properties and fracture behaviour of near eutectic Al Copy Download. Table 6 Results of numerical simulation under different indentation loads. The contact property was tangential behavior, the friction formulation was penalty, the directionality was isotropic and the friction coefficient was 0. Table 3 Results of tensile experiments on rebars. Clad rebars were researched in this study and were hot-rolled through 14 passes according to the hot-rolling process in a steel factory in Guangxi, China. The Al10Sr modifier, broke down the eutectic particles in the microstruc-ture and caused a more homogeneous distribution in the structure. The FEM results, under different indentation loads where the yield stress of the material was MPa are shown in Figure 9. Federal government websites often end in. Table 7 Mechanical parameters of non-uniform region of clad rebar. 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.
