                         Ti6Si2B phases are potentially attractive for structural 
                         applications. However, there is limited information in literature 
                         on effect of alloying in stability of the Ti6Si2B compound, which 
                         presents its single-phase region close to the Ti-22Si-11B alloy 
                         composition (at%). In this sense, this work discusses on 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, scanning electron microscopy, and energy 
                         dispersive spectrometry. 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 mechanically alloyed and heat treated 
                         Ti-6Cu-22Si-11B alloy.",
