Thus, Tarasov et al. demonstrated [5] that a Mg-72 mass%-Ni-20 mass%-Mm(La) alloy, which was prepared by induction melting, reversibly absorbed up to 5.5 mass% of hydrogen, and the system MgMmNi-H 2 demonstrated a much faster H/D kinetics when compared to the non-modified Mg-H 2 Development of a Process for Manufacturing a A full technique of production of a 29N26KKhBTYu-VI precision alloy is developed and implemented. A 500-kg ingot has been melted in Russia for the first time. This ingot is used to form an experimental batch of forged billets 90 mm in diameter and to fabricate hot-rolled metal billets 20 and 30 mm in diameter. The temperature-time deformation conditions, including data on the ductility of the

Effect of surface hardening by high frequency induction

Mar 28, 2006 · Surface hardening of carbon steel by high frequency induction heating (HFIH) produces a considerable increase in its resistance to stress corrosion [1, 2].The magnitude of this increase depends on the depth of surface hardening, on the strength of the specimen core, and on other factors whose influence was studied in this investigation. Failure Analysis of Micro Cracks and Alumina Inclusions Jul 08, 2015 · A tensile test must be conducted for each finished insulator in which a common but significant problem is a low stress mode of fracture. In order to investigate the cause of the low stress fracture in a batch of insulators, a series of failure analysis methods were carried out. As described in this paper, macro-fracture analysis, SEM observation, EDS examination, metallographic structure INDUCTION HARDENING OF TOOL STEEL FOR HEAVILY -treated with induction method and subjected to metallographic preparation, after which complex microstructure investigation wa s performed. The results obtained within the research will be a basis for numerical modelling of the process of induction hardeni ng with potential to be introduced for the aviation industrial components.
