Abstract:
The influence of severe plastic deformation on ongoing phase transformations in metastable β-Ti alloy Ti15Mo was investigated in-situ during linear heating by electrical resistance and complemented by ex-situ microstructure observations using transmission electron microscopy. Several non-monotonic regions in the temperature dependence of electrical resistance were identified and associated with corresponding phase transitions, namely the reversible diffusionless shuffle transformation of athermal ω phase, followed first by diffusion controlled growth of isothermal ω phase and subsequently its continuous dissolution.

Abstract:
The present work is focused on the study of high temperature low cycle fatigue behaviour of Inconel 713LC produced by a vibratory investment casting (VIC) in as-cast conditions and in the condition after heat treatment (HT) consisting of hot isostatic pressing (HIP) followed by precipitation hardening. Low cycle fatigue tests were carried out on cylindrical specimens in symmetrical push-pull cycle under strain control with constant total strain amplitude and strain rate at 800 °C in air. [..]

Abstract:
The microstructure of initial Nd-Fe-B alloy has the substantial effect on the processing and the hysteretic properties of sintered Nd-Fe-B-based magnets. This work is aimed at the structural characterization of the strip-cast Nd-Fe-B alloy, which will be used as the matrix alloy for the preparation of magnets with variable set of functional parameters via the application of REM hydrides or hydrogenated REM compounds added to the powder mixture and using processes of grain boundary diffusion and grain boundary structuring.

Abstract:
The influence of different sintering conditions (sintering temperature and time) on the structure and properties of the investigated tungsten heavy alloy (THA) consisting of tungsten, cobalt, and nickel was evaluated within this study. The samples for sintering were prepared by powder metallurgy techniques (powder mixing followed by isostatic compression), the microstructures were investigated via optical and scanning electron microscopy, and the mechanical properties were investigated by tensile testing.

Abstract:
The surface of Nimonic 80A alloy was melted and rapidly solidified using TIG process (Tungsten Inert Gas) in order to produce a high-strength microstructure to improve cavitation erosion resistance. Cavitation tests, performed on an ultrasonic vibrator at a frequency of 20 kHz and at amplitude of 50 μm oscillations pointed out that these microstructure changes lead to significant differences in the behavior of this alloy to erosion generated by vibrator cavitation.

Abstract:
γ-TiAl based alloys are very perspective materials thanks to their outstanding properties, such as high specific strength, low density, high modulus of elasticity, good oxidation resistance and resistance to creep. At present, the greatest attention is paid to TiAl alloys which contain relatively high content of refractory metals such as Nb, Ta, Mo and W. [..]
