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 ...
High-Pressure Assisted Sintering of Ti-20Si-10B and Ti-10Si-5B Powders
(Trans Tech Publications Ltd, 2012-01-01)
This work presents the structural characterization of Ti-10Si-5B and Ti-20Si-10B (at-%) alloys produced by high-pressure assisted sintering. Sintering was performed in air at 1100 and 1200 degrees C for 60 s using pressure ...
Powder Metallurgy Production of Ti-2 Wt Pct Si Alloy: Structural, Mechanical, and Electrochemical Characterization of the Sintered Material.
Several commercial alloys use silicon (Si) to improve titanium (Ti) resistance to creep and oxidation at high temperatures and to improve Ti corrosion resistance in acid media. According to the Ti-Si phase diagram, reported ...
Synthesis and electrochemical properties of Ti-Si alloys prepared by mechanical alloying and heat treatment.
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, ...
