Microstructure and Mechanical Properties of Large-Scale Ingots of the Zr-1Mo Alloy
نویسندگان
چکیده
A large-scale ingot of Zr-1Mo alloy was produced for industrial manufacturing to investigate whether it is possible to produce an ingot with homogeneity. The homogeneous ingot with a chemical composition of Zr-1mass%Mo was prepared successfully. The microstructure, mechanical properties, and magnetic susceptibility were evaluated. The microstructure showed a coarse colony structure of a plate-like ¡ phase and a thin ¢ phase. An 1⁄2 phase precipitation was observed in the ¢ phase. Elongation of 23% and magnetic susceptibility of 12.4 © 1019m3 kg11 (0.98 © 1016 cm3 g11) were achieved. We found that it is possible to produce a homogeneous large-scale ingot of Zr-1Mo with high elongation and low magnetic susceptibility. [doi:10.2320/matertrans.M2015098]

This study focused on the effect of electro slag remelting process (ESR) on microstructure and composition of an as-cast alloy of Cu-Cr-Zr. These observations revealed that applying ESR process results in a more uniform distribution of alloying elements, however a slight aggregation of large precipitates and inclusions existed in as-cast ingot was found. Additionally, impurities like P, S and M...
متن کاملEffects of Zr Additive on Microstructure, Mechanical Properties, and Fractography of Al-Si Alloy
The effects of Zr additive on the microstructure, mechanical properties, and fracture behavior of Al-Si alloy were systematically investigated. The additive of Zr obviously reduced the size of Si particles and changed its morphology. Grain size refinement was promoted by the reaction between Al and Zr forming Al3Zr and ZrSi2 compounds. Compared to a Zr-free alloy, the additive enhanced the tens...
