abstract = "Metal matrix multicomponent alloys and others based on the
Ti+Ti6Si2B phases are potentially attractive for structural
applications. However, there is limited information in literature
on the effect of alloying in stability of the Ti6Si2B compound,
which presents its single-phase region close to Ti-22Si-11B alloy
composition (at.-%). In this sense, this work discusses on the
effect of copper addition on the stability of the Ti6Si2B
compound. Elemental powder mixtures were used to prepare the
Ti-xCu-22Si-11B (x=2 and 6 at.-%) alloys by high-energy ball
milling and subsequent heat treatment (1100ºC for 240 minutes).
The as-milled Ti-Cu-Si-B powders and heat-treated samples were
characterized by X-ray diffraction (XRD), scanning electron
microscopy (SEM), and energy dispersive spectrometry (EDS).
Similar behavior was noted during ball milling of Ti-Cu-Si-B
powders, i.e., the Ti5Si3 phase was formed after milling for 180
minutes. The mechanically alloyed and heat treated Ti-2Cu-22Si-11B
alloy presented a matrix of Ti6Si2B dissolving close to 2 at.-%
Cu. Precipitates of Ti5Si3 and other unknown Cu- and Fe-rich phase
were also identified in microstructures of these quaternary
alloys, whose amounts were increased in the mechanical alloyed and
heat treated Ti-6Cu-22Si-11B alloy.",
