                         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.",
