Abstract:
Due to the high biocompatibility of magnesium, magnesium based alloys are considered as suitable materials for the production of biodegradable implants such as the fixators of fractured bones or stents. The main insufficiencies of pure magnesium are lower yield and ultimate strength and high corrosion rate. [..]

Abstract:
Development of titanium matrix composites (TMCs) appeared to be an effective way to improve wear and friction properties of titanium, especially though the melting route approach. In this case, the reinforcements are formed during phase transformations, obtaining a good interfacial strength with the matrix. [..]

Abstract:
In-situ Low Cycle Fatigue test (LCF) at temperature 635 °C have been performed in Scanning Electron Microscope (SEM) equipped with Electron Backscatter Diffraction analysis (EBSD) on a small dog-bone-shaped specimen of cast Inconel 713LC superalloy. The aim of the work was to study early stage fatigue damage at high temperature by the observations of the characteristic surface relief evolution and crystallographic characterization changes by EBSD together with post observation of internal dislocation structures on FIB prepared TEM lamella.

Abstract:
Microstructure evolution, Vickers hardness and Vickers microhardness were investigated in intermetallic TiAl-based alloy with nominal composition Ti-48Al-2Nb-1Cr-0.2Si (at.%). The samples prepared from the as-received ingot and centrifugally cast turbocharger wheel were subjected to the heat treatment consisting of isothermal annealing at temperatures ranging from 1150 to 1320 °C in protective argon atmosphere and air cooling to room temperature.

Abstract:
The deformation-aging process developed by us for the alloy (wt.%) 16 Co - 33 Cr - 2 Cu - 0.5 Nb - Fe (balance) includes the (1) quenching from 1100 °C to form the single-phase α-solid solution, (2) aging resulting in the formation of spherical α1-phase precipitates during cooling in a temperature range of 650 - 625 °C at a rate of 40 °C/h; (3) monoaxial plastic deformation with the ε = 79 % reduction of area in order to give the shape anisotropy of α1-phase precipitates and to produce the mechanical texture, and (4) final controlled cooling from 605 °C to 540 °C at a rate of 8 °C /h, in the course of which the more complete compositional separation of strongly magnetic α1-phase and weakly magnetic α2-matrix precipitates is reached. The developed heat treatment allowed us to obtain the following magnetic characteristics of the Kh33K16D2B alloy: %& = 64-64.5 kA/m, Br = 1.02-1.1 T and (BH)max = 41.4 - 42.2 kJ/m3.. [..]

Abstract:
In nickel-based turbocharger castings, defined macrostructure and microstructure are required in addition to internal homogeneity and mechanical and creep properties. The structure is given in particular by the orientation and maximum dimensions of dendritic and equiaxed grains and by the extent of admissible microporosity and carbide phases. [..]
