Abstract:
The main objective of severe plastic deformation (SPD) methods is to obtain material with ultra-fine grained microstructure. Large deformations introduced during SPD processes result in extensive refinement of initial coarse microstructure which has significant influence on overall mechanical properties of such materials.

Abstract:
Twin-roll casting is a technique which allows production of high quality thin magnesium alloys strips with enhanced microstructure. However, further treatment using severe plastic deformation or annealing is required to improve mechanical properties of strips. [..]

Abstract:
In this year at our workplace (the Department of Engineering Technology - Technical University of Liberec) we were engaged in metallurgical research on copper and its alloys, especially crystallization. This research was never widely performed in the Czech Republic (even in times of Czechoslovakia) it was due to the demanding technologies of copper alloy castings and also because the melting of alloys must be provided with the necessary melting facilities. [..]

Abstract:
Cu60Zr30Ti10 (at.%) metallic glass was prepared in two forms: as a rod of diameter 3 mm and length of 26 mm and as a thin ribbon wide 5 mm and thick 35 μm. Chemical composition of the alloys was as certain by Scanning Electron Microscopy (SEM) coupled with EDX analysis. [..]

Abstract:
Zn and Zn-based alloys attract interest due to an ability to protect steel surface against corrosion. Thin surface layer of a protective zinc alloy is usually prepared by hot dip galvanizing and acts as a barrier against corrosive environment or as a sacrificial anode in case the bare steel surface is exposed.

Abstract:
With every tonne of pig iron being produced, over 10 kg of flue dust is generated. Direct recycling of this material is unacceptable mainly due to its high zinc content. [..]

Abstract:
Cast TiAl alloys with high Nb content are subject of extensive research with the aim to develop material with low density, good corrosion resistance and high strength at elevated temperatures. Disadvantage of their broad applications is restricted workability, machinability and low fracture toughness especially at room temperature. [..]

Abstract:
In Ni rich Ni–Ti alloys, various phases such as hexagonal Ni3Ti, cubic NiTi2 and rhombohedral Ni4Ti3 appear during heat treatment. The presence of these precipitates affects the shape memory effect and superelasticity in an important manner. [..]

Abstract:
One bi-layer Ni-Ti thin films with chemical compositions of Ni45TiCu5/Ni50.8Ti (numbers indicate at.%) determined by energy dispersive X-ray spectroscopy was deposited on Si substrates using RF magnetron sputtering. The structures and transformation temperatures of annealed thin films at 773 K for 1 h were studied using grazing incidence X-ray diffraction (GIXRD) and differential scanning calorimetry (DSC), respectively.

Abstract:
Viscoplasticity and crystal plasticity have been used to model cyclic deformation of nickel-based superalloys at elevated temperature. Model parameters were determined from strain-controlled cyclic test data, with consideration of strain rate effects. [..]

Abstract:
The aim of the work was to determine the microstructure effect on the tribological properties of the Monel K-500 alloy. The supersaturation temperature of 1150 °C was selected in such a way so that it would exceed the solution temperature of the carbides present in the Monel K-500 alloy by less than 10 °C. For the annealing temperature assumed in this way, the annealing time was assumed to be 1 h, 2 h and 4 h. [..]

Abstract:
The microstructures of two nickel based alloys Ni-Cr-Al-C-(Nb) containing chromium and chromium plus niobium carbides were investigated. These alloys unlike commercially available nickel based superalloys contain a high volume fraction of carbides to obtain high wear resistance. [..]

Abstract:
In the work the results of the structural perfection of the cellular and dendrite single crystals with the diameter 24 mm of the Ticonal 9 alloy: 35 % Co – 14.5 % Ni – 7 % Al – 4 % Cu – 5 % Ti – Fe the rest (in wt.%) at the growing rates (R) from 0.1 to 9 mm/min with the constant temperature gradient 10 – 12 K/mm are presented. The block size decrease from 2.3 mm at R = 0.1 mm/min to 1 mm at R = 9 mm/min at the simultaneous disalignment increase from 1.8° to 7.8° accordingly was revealed. [..]
