BACKGROUND Zirconia materials are known for their optimal aesthetics, but they are brittle, and concerns remain about whether their mechanical properties are sufficient for withstanding the forces exerted in the oral cavity. Therefore, this study compared the maximum deformation and failure forces of titanium implants between titanium-alloy and zirconia abutments under oblique compressive force...

In this study, Ti-5Al-2.5Fe alloy was prepared by powder metallurgy. The elemental titanium, aluminum, and iron powders were mechanically alloyed for 10 h in a vacuum atmosphere. A stainless steel jar and stainless steel balls were used for mechanical alloying. The alloyed powders were then sintered by vacuum hot pressing at 950 °C for a soaking time of 30 minutes. Pure titanium was also sinter...

Abstract Shape memory alloy hybrid composites have promise in realizing the 21st century goal of morphing structures. There is considerable work to be done development characterization and modeling techniques for these materials. The proposed methodology adapts existing standards include previously omitted factors required numerical modelling shape alloys their integration into end-use applicat...

background: sterilization techniques could affect the characteristics of orthodontic wires. the aim of the present study was to evaluate the effect of steam and dry heat sterilization techniques on load-defl ection behavior of fi ve types of β-titanium alloy wires. materials and methods: the samples consisted of 30 straight lengths of fi ve types of β-titanium alloy wires: titanium molybdenum a...

The results of investigation the diffusion interaction kinetics at boundary explosion welded Ti-NiCr system compositions during heat treatment are presented. structure, chemical and phase composition formed zones also studied. It is shown that layered zone a temperature below eutectoid transformation. Diffusion consists solid solutions based on Ti2Ni, TiNi, TiNi3 intermetallic compounds, as wel...

NiTi alloy is a highly functional of Ni (nickel) metal and Ti (titanium) used for engineering. This has good biocompatibility properties against human body tissues so that currently it widely medical devices. study aims to determine the effect temperature on tensile strength Nanopillars investigate behavior atoms making up nanopillars due loading. From results obtained, authors found greatest v...

Screw-in effect is one of the unintended phenomena that occurs during the root canal preparation with nickel-titanium rotary files. The aim of this study was to compare the screw-in effect among various nickel-titanium rotary file systems. Six different nickel-titanium rotary instruments (ISO 20/.06 taper) were used: K3 (SybronEndo, Glendora, CA, USA), Mtwo (VDW GmbH, München, Germany), NRT wit...
