Abstract A wire of a β-Titanium alloy known as Gum Metal was cold rolled to reduction 80% and heat treated for times in the range 3-120 minutes at fixed temperature 740 °C yield set partially recrystallized microstructures. The recrystallization course evaluated by light optical microscopy Electron Backscatter Diffraction, based on which kinetics analysed using Johnson-Mehl-Avrami-Kolmogorov (J...

An innovative method to successfully erupt buccally impacted canines in difficult positions, that is, sector III and IV mesial the root of lateral incisors into occlusion, has been described. 3-dimensional retraction spring is fabricated using 0.017 × 0.025-inch Titanium Molybdenum Alloy(TMA) wire 45-degree bends are made simultaneously 2 directions. The first bend given distally starting from ...

background: friction is usually encountered during sliding technique for orthodontic space closure. this study aims to investigate the effect of fluoride on frictional resistance between stainless steel orthodontic brackets and steel and niti arch wires. materials and methods: a total of 144 standard 022 stainless steel brackets were used in this experimental study. 0.016 and 0.019 × 0.025 inch...

In order to optimize the additive manufacturing process and find parameters affecting mechanical properties of parts, an simulation model Ti-6Al-4V titanium alloy was established, effects ambient temperature, substrate thickness wire temperature on stress field residual were analyzed. The results show that is inversely proportional cladding layer, while are positively correlated layer. When inc...

Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...

Scanning electron microscopy, 3D optical surface profilometry, as well X-ray diffraction and backscatter analysis were implemented for studying the effects of both ultrasonic impact treatment (UIT) electrospark (UIET) procedures on microstructure, phase composition, mechanical tribological properties Ti-6Al-4V samples fabricated by wire-feed beam additive manufacturing. It was shown that he UIE...

BACKGROUND The zygomatic maxillary complex (ZMC) fractures are one of the most frequent injuries of the facial skeleton due to its position and facial contour. Assaults, road traffic accidents and falls are the principal etiologic factors that may cause fractures of zygomatic bone. The different fixation methods are applied to treat the zygomatic bone fractures, with many more classifications w...

Wire arc additive manufacturing (WAAM) can be used to repair blades or blisk made of titanium alloy with the advantage high efficiency and low-cost. In this work, finite element model repairing blade based on heat source was established investigate it. Results showed that maximum effect thermal undercooling appeared when peak current transformed base (1 Hz 5 Hz), which will promote grains refin...

MicroRNAs (miRNAs) have emerged as new candidates as diagnostic and prognostic biomarkers for the detection of a wide variety of cancers; thus, sensitive and selective detection of microRNAs is significant for early-phase cancer diagnosis and disease prevention. A novel and simple electrochemical miRNA biosensor was developed using Cd(2+)-modified titanium phosphate nanoparticles as signal unit...
