چکیده

This paper presents the results of a comprehensive study erosive wear resistance, strength, and adhesive characteristics high-temperature structural titanium alloy Ti-5.7Al-3.8Mo-1.2Zr-1.3Sn (the Russian grade VT8M-1) with coarse-grained ultrafine-grained (UFG) structures protective erosion-resistant TiVN coating produced by physical vapor deposition (PVD), deposited on surface. A microscopic analysis areas subjected to action abrasive particles was performed, different characters were revealed depending state alloy. The obtained convincingly demonstrate that means refining grain structure alloys depositing ion-plasma surface, it is possible significantly increase erosion resistance materials operating under high loads in aggressive environments.

Mechanical Behavior of an Ultrafine/Nano Grained Magnesium Alloy

The application of magnesium alloys is greatly limited because of their relatively low strength and ductility. An effective way to improve the mechanical properties of magnesium alloy is to refine the grains. As the race for better materials performance is never ending, attempts to develop viable techniques for microstructure refinement continue. Further refining of grain size requires, however...

Evolution of texture in an ultrafine and nano grained magnesium alloy

The evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (ABE). The microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°C were characterized. The results showed that after single ABE pass at 100°C an ultrafine/nano grained microstr...

Dynamic observations of deformation in an ultrafine-grained Al–Mg alloy with bimodal grain structure

The tensile properties and deformation response of an ultrafine-grained (UFG) Al–Mg alloy with bimodal grain structure were investigated using a micro-straining unit and a strain mapping technique. Atomized Al 5083 powder was ball-milled in liquid N2 to obtain a nanocrystalline (NC) structure, then blended with 50 wt.% unmilled coarse-grained (CG) powder, and consolidated to produce a bimodal g...

Microalloying Ultrafine Grained Al Alloys with Enhanced Ductility

Bulk ultrafine grained (UFG)/nanocrystal metals possess exceptional strength but normally poor ductility and thermal stability, which hinder their practical applications especially in high-temperature environments. Through microalloying strategy that enables the control of grains and precipitations in nanostructured regime, here we design and successfully produce a highly microstructure-stable ...

ELECTRODEPOSITION OF NANO SIZE HYDROXYAPATITE COATING ON TI ALLOY

A film of osteoconductive and biocompatible material on biomedical metallic implants can create bioactivity of the implant and shorten healing time. Hydroxyapatite, that is the most important mineral part of human bone, was coated on Ti6Al4V using cathodic electrode position process. Pulse electrode position technique was used and the effects of different parameters such as potential, duty cycl...
