Multilayered Nano-Microcomposite Ti-Al-N/TiN/Al2O3Coatings. Their Structure and Properties

Effect of Severe Plastic Deformation on Structure and Properties of Al-Sc-Ta and Al-Sc-Ti Alloys

The comparative analysis of the effect of monotonous and non-monotonous severe plastic deformations (SPD) on the structure and properties of aluminum alloys has been carried out. Conventional hydrostatic extrusion (HE) with a constant deformation direction and equal-channel angular hydroextrusion (ECAH) with an abrupt change in the deformation direction were chosen for the cases of monotonous a...

Mechanical Properties of Nano-Structure Controlled Ti-Hf Alloy for Dental

Ti-Hf alloy system forms an α-β isomorphous system and does not form any intermetallic compounds, which is also beneficial for good mechanical properties. The aim of this study was the improvement of mechanical property and biocompatibility by Hf addition to Ti-alloy. Ti-Hf(10, 20, 30 and 40wt%) alloys manufactured by non consumable vacuum arc melting furnace. All the specimens were nanostructu...

Structure, hardness and thermal stability of Ti(Al,N) coatings

In the past two decades, coatings of the Ti–Al–N ternary system have attracted considerable research and industrial interest. Nevertheless, the Ti–Al–N system still offers new interesting possibilities for coating developments such as the addition of low N contents to Ti–Al films in order to reach a good compromise between high hardness and a low friction coefficient. Ti–Al–N coatings with low ...
