New Phases in the Ti-P and Ti-Cu-P Systems.

Corrosion Characteristics of a - Ti and Ti 2 Cu Composing Ti - Cu Alloys

A series ef binary Ti-Cu alloys containing 5-20 mass% Cu was prepared, and the corresien behavior of a-Ti and Ti2Cu composing the Ti-Cu alloys were examined based on the anodic polarization curves and released iens in O.9% NaCl and 1% lactic acid solutions. In both selutions, the Ti-Cu alloys showed the same anodic polarization curves as titanium in the conditien below 1.4 V. Hewever, precipita...

Assessing the Performance of LiF:Mg,Ti and LiF:Mg,Cu,P Extremity Dosemeters

In this paper, we present the results aimed at assessing the performance of two varieties of LiF detectors (LiF:Mg,Ti and LiF:Mg,Cu,P, of the EXTRAD type), relatively to reproducibility, detection threshold and angular dependence criteria defined in the ISO 12794:2000 Standard and other documents. The fading properties of these two dosemeter varieties were also investigated. In all experiments,...

High Reliable Cu Damascene Interconnects with Cu/Ti/TiN/Ti Layered Structure

We studied the effect of inserting a Ti layer between the Cu and TiN layers on the interconnect resistance and on the resistance toward electromigration (EM) of the damascene interconnects. As a result, it became clear that, by inserting the Ti layer, the adhesion of the Cu to the underlayer could be improved. By inserting the thin Ti layer with atmospheric exposure, we were able to hold down t...

Preparation and Characterization of the First Binary Titanium Azides, Ti(N3)4, [P(C6H5)4][Ti(N3)5] and [P(C6H5)4]2[Ti(N3)6] and on Linear Ti-N-NN Coordination

New Cu-Free Ti-Based Composites with Residual Amorphous Matrix

Titanium-based bulk metallic glasses (BMGs) are considered to have potential for biomedical applications because they combine favorable mechanical properties and good biocompatibility. Copper represents the most common alloying element, which provides high amorphization capacity, but reports emphasizing cytotoxic effects of this element have risen concerns about possible effects on human health...
