In a recent experimental campaign, we used laser-accelerated relativistic hot electrons to ensure heating of thin titanium wire targets up warm dense matter (WDM) state [ EPL 114 , 45002 ( 2016 ) 10.1209/0295-5075/114/45002 ]. The WDM temperature profiles along several hundred microns the were inferred by using spatially resolved X-ray emission spectroscopy looking at Ti K ? characteristic line...

INTRODUCTION Various anchorage techniques have been designed for canine retraction. Intraoral techniques have not always been successful, and now implants are widely used for this purpose. A new type of titanium microimplant, with a small diameter and a button-like head, was shown to be an effective source of anchorage for distal movement of the canines. The purposes of this study were to measu...

INTRODUCTION The purpose of this study was to compare the frictional force (FF) generated by various combinations of self-ligating bracket (SLB) types, archwire sizes, and alloy types, and the amount of displacement during the initial leveling phase of orthodontic treatment, by using a custom-designed typodont system. METHODS Two passive SLBs (Damon 2 [D2] and Damon 3 [D3]), and 3 active SLBs...

CONTEXT Reconstruction of mandibular defect is a challenge to the head and neck surgeon because of associated functional and esthetic problems. Our experience with the use of nonvascularized iliac crest bone graft is hereby reported. AIM The aim was to report our experience with the use of nonvascularized iliac crest bone for mandibular defect reconstruction at University College Hospital, Ib...

Stacks consisting of titanium, platinum, and gold layers constitute a popular metallization system for the bond pads semiconductor chips. Wire bonding on such layer stacks at different temperatures has extensively been investigated in past. However, reliable information bondability this after high-temperature sintering process is still missing. When performing wire pressure (at, e.g., 875 °C), ...

WaveOne Gold, ProTaper Reciproc Blue, Next, and files were selected to compare the phase transformation behaviors mechanical properties of nickel-titanium (NiTi) rotary after gold heat blue treatments. The reverse finishing point temperatures Next higher than those other two instruments investigated. At a deflection 0.5 mm, loads significantly varied except for Gold. 3.0 Blue Gold compared ProT...

The work is devoted to a review of modern achievements in the field wire-feed electron beam additive manufacturing. features structure formation aluminum, copper, titanium, nickel-based alloys, and steels during 3D printing are shown. Aspects directional solidification production components from various metals alloys considered. prospects for obtaining composite functionally graded materials ba...

The surface topography of 100 clinically used archwires of stainless steel, beta-, or nickel-titanium were investigated that had contacted either ceramic or stainless steel brackets. One group consisted of two sets: 60 wires with no treatment records accessed to bias analyses, and 40 wires for which extensive clinical records were available, half of which were used with ceramic or stainless ste...

A self-developed Ti-Al-V-Mo system titanium alloy flux-cored wire was used to join the Ti64 plate via laser welding with filler wire. The microstructure and properties of obtained welded joint were investigated. results showed WM (welded metal) consisted mainly acicular α’ martensite, HAZ (heat affected zone) comprised a primary αp phase, Widmanstatten, few martensite residual β phase. strength...

The influence of titanium alloy (Ti–5Al–2.5Sn) and commercially pure (cpTi) as fillers on dissimilar pulsed tungsten inert gas weldments Ti–5Al–2.5Sn/cpTi was investigated in terms microstructure, mechanical/nano-mechanical properties, residual stresses. A partial martensitic transformation observed the for all welding conditions due to high heat input. microstructure evolved FZ/cpTi interfacia...
