Evaluation of Ti(3)Si Phase Stability from Heat-Treated, Rapidly Solidified Ti-Si Alloys
(SPRINGER, 2010)
Ti-base alloys containing significant amounts of silicon have been considered for high temperature structural applications. Thus, information concerning phase stability on the Ti-Si system is fundamental and there are not ...
Simplification on the thermodynamic description of the Ti-Si- system
(Associação Brasileira de Metais - ABMSão Paulo, 2016-01)
The thermodynamic optimization of ternary or higher order systems containing Ti requires that the Ti-X binary
systems are continuously updated. The Ti-Si system has been studied and thermodynamically optimized since de ...
On Ti-18Si-6B and Ti-7.5Si-22.5B powder alloys prepared by high-energy ball milling and sintering
(ABM, ABC, ABPol, 2012-12-01)
Recently, a new ternary phase was discovered in the Ti-Si-B system, located near the Ti6Si2B composition. The present study concerns the preparation of titanium alloys that contain such phase mixed with α-titanium and other ...
Synthesis and Electrochemical Properties of Ti-Si Alloys Prepared by Mechanical Alloying and Heat Treatment
(2018)
The aim of this work was to study the synthesis and electrochemical properties of Ti 2 wt %-Si alloys prepared by mechanical alloying (MA) and heat treatment. The MA process was performed under Ar atmosphere. The structural, ...
Rapid solidification and phase stability evaluation of Ti-Si-B alloys
(ELSEVIER SCIENCE SA, 2011)
Ti-rich Ti-Si-B alloys can be considered for structural applications at high temperatures (max. 700 degrees C), however, phase equilibria data is reported only for T = 1250 degrees C. Thus, in this work the phase stability ...
Wetting behaviour of silicon nitride ceramics by Ti-Cu alloys
(ELSEVIER SCI LTD, 2008)
The wetting of Ti-Cu alloys on Si3N4 was analyzed by the sessile drop method, using an imaging system with a CCD camera during the heating under argon flow. The contact angle was measured as a function of temperature and ...
Structural properties and visible emission of Eu3+-activated SiO2–ZnO–TiO2 powders prepared by a soft chemical process
(2016-12-01)
In this work, the structural and optical properties of the 60SiO2–20ZnO–20TiO2 system (in mol%) doped with 1 mol% of Eu3+ were evaluated. Stable and transparent sols, homogeneous gels, and powders were prepared by a soft ...
