Study and analysis of the structural constituents of billets hardened by fine-grained particles and formed by centrifugal casting

The structural and phase constituents of metal samples cut from hollow tube billets hardened by fine tungsten and silicon carbides and formed by centrifugal casting are studied.

Interaction between tungsten monocarbide and an iron-based metallic melt

A technique and results of investigation of compacted tungsten carbide substrates by scanning microscopy are reported. Samples are prepared in the course of studies of the wettability of tungsten carbide substrates with the iron melt, which are performed in accordance with the sessile drop method using two different heating strategies, namely, contact and noncontact heating of metal.

Experiments on Obtaining Nanostructured Metallic Materials and their Investigation

This paper describes experiments on the introduction of fine particles in the melt is crystallized in the preparation of centrifugally cast billets. To predict the distribution of particles in the crystallizing melt was conducted mathematical modeling of the process. To confirm the data obtained by mathematical modeling experiments were conducted to obtain a centrifugal-cast billets with the introduction of fine particles. The investigation of the microstructure of the samples obtained. Comparing the data obtained about the conduct of computer simulation and real experiment, the distribution of particles in the melt crystallizing. In conclusion, this article presents the findings of the work done.

Development of an Optimal Heat Treatment Regime for a Gradient Material Containing Tungsten Carbide

One of the main processes in metal products is heat treatment. However, existing regimes of heat treatment are not suitable for the new gradient metals. This article presents a method of obtaining gradient metallic materials and heat treatment development. Also presents the studies results of heat treatment effect on mechanical properties and metal structure.

Yttrium Oxide Wetting Angle Examination

The current paper presents yttrium oxide wetting angle examination. The test was performed in accordance with two different methods: contact and noncontact heating. Upon completion of the test, microstructural and spectral analysis of substrate/metal contact areas was conducted. Test findings are listed in the Conclusions.

The Study of the Contact Angle of Silicon Carbide High-Carbon Iron Melt

The current paper concerns the angle of silicon carbide wetting with high-carbon molten iron under vacuum. Our research was conducted with a wetting examination complex at the Institute of Energy and Interfacial Interactions (Genoa, Italy). It has been revealed that reaction of the substrate with a high-carbon molten metal results in the gaseous phase formation. We have also ascertained the temperature rate at which the substrate/metal reaction with gas formation starts.
