ESCA studies of Fe-Ti alloys

Applied Physics A Solids and Surfaces, 1992
Fe-Ti alloys containing 5 to 47% Ti have been studied by ESCA. The alloys were exposed to 0.1 M NaCl for 24 h under open-circuit potential (OCP) during which passive films were formed. The passive film consisted of FeO and TiO2 in the inner layer while Fe2O3, water, and hydroxyl groups were present in the outermost monolayers, irrespective of ...

Studies of Ti alloys for dental castings

Dental Materials, 1989
Casting of Ti has been recently investigated in dentistry. The purpose of this study was to examine the alloying effect on the cast Ti. Metallurgical structures, mechanical properties, and in vitro corrosion resistance were, therefore, studied for cast Ti and for four selected cast Ti alloys such as Ti-6AI-4V, Ti-15V, Ti-20Cu, and Ti-30Pd. A "Castmatic"

Oxidation of Ti-1Si and Ti-5Si alloys

Oxidation of Metals, 1982
Oxidation kinetics of Ti-1 wt. % Si and Ti-5 wt. % Si alloys in either pure oxygen or air under a pressure of 0.93 bar and in the temperature range of 1171–1473 K are reported. For the exposure period investigated (up to 12 h) both alloys oxidized slower than pure Ti. The amount of oxygen dissolved in the Ti-1 wt. % Si alloy has been calculated.

Reaction of Ti and Ti-Al alloys with alumina

Metallurgical Transactions A, 1991
The reaction of single-crystal Al2O3 with pure Ti and Ti-Al alloys with different Al concentrations was examined in the temperature range of 1173 to 1573 K. Significant reaction occurred between A12O3 and the Ti-Al alloys with Al concentrations lower than that corresponding to the γ-TiAl phase.

Mechanical alloying of the Al–Ti system

Philosophical Magazine B, 1990
Abstract We have investigated the possibility of an amorphization reaction by mechanical alloying for two compositions of the Al–Ti binary system. While the Al-rich composition Al75Ti25 appears to give, after milling for 21 h, an Al(Ti) highly cubic phase, the Ti-rich composition Al25Ti75 does amorphize using various milling conditions. The progress of

Grindability of cast Ti–Cu alloys

Dental Materials, 2003
The purpose of the present study was to evaluate the grindability of a series of cast Ti-Cu alloys in order to develop a titanium alloy with better grindability than commercially pure titanium (CP Ti), which is considered to be one of the most difficult metals to machine.Experimental Ti-Cu alloys (0.5, 1.0, 2.0, 5.0, and 10.0 mass% Cu) were made in an ...

Elastic moduli of cast Ti–Au, Ti–Ag, and Ti–Cu alloys

Dental Materials, 2006
This study investigated the effect of alloying titanium with gold, silver, or copper on the elastic properties of the alloys.A series of binary titanium alloys was made with four concentrations of gold, silver, or copper (5, 10, 20, and 30 mass%) in an argon-arc melting furnace.

Asymmetric alloy formation at the Fe-on-Ti and Ti-on-Fe interfaces

Journal of Physics: Condensed Matter, 2018
Abstract The Fe-on-Ti and Ti-on-Fe interfaces were studied experimentally by Mössbauer spectroscopy (MS), transmission electron microscopy (TEM) and x-ray reflectometry (XRR) on Ti/Fe/Ti trilayers grown on Si(1 1 1) substrates by vacuum evaporation. The nanoscale structure and composition were explored in cross sections using TEM, the
