Abstract:
Due to the reduction in production costs, not only in the automotive industry, more and more sandwich-structure parts are emerging to replace expensive, technologically complex elements such as cooling rotors in electrical installations. They are required to meet a complex set of attributes – resistance to abrasive wear, anti-corrosion requirements, and especially manufacturing costs.This article discusses and compares the mechanical properties of a critical part (cooling rotor) made as a sandwich structure of aluminum alloys and nickel-phosphorus (NiP) coatings.The specific mechanical and corrosive properties of the thin NiP film vary with the percentage of phosphorus and the heat treatment.

Abstract:
In recent years, the cerium-based conversion coatings have been increasingly used as one of the more promising chromate coatings substitutes on aluminum alloys, as cerium compound do not pose environmental problems and the coatings provide an efficient corrosion protection close to that of chromium. The cerium-based layer was prepared from simple immersion of aluminium alloy sheets in a solution composed of a 4 - 8 g·L-1 Ce(NO3)3·6H2O; 30 - 50 ml·L-1 H2O2 (37 %) and 0.5 - 1,5 g·L-1 tannin at room temperature.

Abstract:
Commercially pure titanium was prepared by advanced powder metallurgy methods with the aim to produce the ultra-fine grained material. Cryogenic attritor milling was used as a first step to refine the microstructure at liquid argon temperatures to suppress recovery and dynamic recrystallization. [..]

Abstract:
Beta titanium alloy, Ti-35Nb-6Ta-7Zr-0.7O (wt.%), differs from most of Ti-Nb-Zr-Ta based biomedical alloys by its very high oxygen content, which provides a significant interstitial solution strengthening. However, there is a need for thermomechanical processing due to the poor fatigue resistance after casting. [..]

Abstract:
Phase transformations in several metastable β-titanium alloys were studied during linear heating by in-situ electrical resistance measurement. The initial decrease of electrical resistance is caused by a reverse shuffle transformation of athermal ω phase particles to β matrix. [..]

Abstract:
Anomalous X-ray diffraction measurements were performed on a metastable β titanium alloy (Ti-15 wt% Mo) containing thermodynamically metastable ω phase particles. The dependence of diffracted intensity on primary beam energy was measured for selected ω and β diffraction maxima for energies near the MoK absorption edge (20.0 keV). [..]

Abstract:
Ti-6Al-4V alloy is mostly used for dental and hard tissue implants, due to its high strength to weight ratio, high corrosion resistance, and relatively low elastic modulus. However, apart from health concerns of V ions release and higher Young’s modulus (~120 GPa) than human bone (~30 GPa), recent research indicates day-to-day cyclic loading instead of a single-load event such as a fall, might be the consequence of inherent stiffness of fixation implants.

Abstract:
Multi-component alloys containing at least five elements in equimolar or near equimolar ratio are commonly known as High-Entropy Alloys. Despite the complex chemical composition, with the fulfilment of specific thermodynamic parameters, they are characterized by the existence of simple phases. [..]

Abstract:
The research problem focuses on the wires made of aluminum alloys acquired in the wire drawing process of the wire rod obtained using the Continuus Properzi method. The nature of the drawing process generates a heterogeneity of strain on the wire cross-section, which results in the formation of internal stresses. [..]

Abstract:
Twin-roll casting allows production of sheets and strips with required thickness without subsequent homogenization or hot rolling and therefore has a high potential for industrial applications. One of the drawbacks of this method is a formation of inhomogeneous structure with central segregation. [..]

Abstract:
The results of investigations of the structure and mechanical properties of in-situ aluminum matrix composites based on the Al-Mg-Si system reinforced with primarily crystallizing silicides Mg2Si are presented. The main advantage of such materials is the usage of relatively inexpensive initial components with absence of the necessity for the use of powders, which greatly simplifies technology and reduces the production cost of castings.

Abstract:
It is shown from the point of view of the quasicrystalline model of metallic melts that during the liquid phase treatment by nanosecond electromagnetic pulses it may be possible the occurrence of energy fluctuations in the melt, change of short-range order structure in the atoms arrangement, reducing the cluster size and shortening their lifespan, decreasing the disordering temperature. These processes change the physical properties of the melt, crystallization parameters, physical-mechanical and operational properties of the obtained alloys. [..]
