“…The ageing is carried out at 400÷600°C for up to several hours. This allows to achieve strength properties and electrical conductivity that are comparable to those obtained for Cu-Be alloys [5,14,15]. The use of thermomechanical treatment and ageing enables to obtain higher strength properties.…”

“…Their strong toxicity caused that their use has been banned in Poland and EU countries for many years [3]. The research, conducted for many years all over the world, focused on finding non-toxic substitutes for beryllium bronzes have shown that these can be Cu-Ti binary alloys or Cu-Ti-X complex alloys, called titanium bronzes [1,2,[4][5][6][7].…”

This paper presents the possibilities of forming the microstructure as well as mechanical properties and electrical conductivity of Cu-3Ti alloy (wt.%) in thermal and thermomechanical processes that are a combination of homogenising treatment, hot and cold working, solution treatment and ageing. Phase composition of the alloy following various stages of processing it into the specified semi-finished product was being determined too. It was demonstrated that the application of cold plastic deformation between solution treatment and ageing could significantly enhance the effect of hardening of the Cu-3Ti alloy without deteriorating its electrical conductivity. It was found that for the investigated alloy the selection of appropriate conditions for homogenising treatment, hot and cold deformation as well as solution treatment and ageing enables to obtain the properties comparable to those of beryllium bronzes.

“…% Ti, capable of being a proper substitute for well-known alloys, such as Cu-Be alloys. Formation of ordered metastable ' (Cu 4 Ti) precipitates in Cu-Ti alloys during ageing increases their mechanical and electrical properties [1][2][3]. The mechanism of precipitation hardening in Cu-Ti binary alloys is a matter of much debate.…”

Age hardenable Cu-1wt. % Ti-1wt. % TiB 2 composite was produced by adding boron powder to CuTi melt. TiB 2 nano particles formed via in situ reaction in the melt. This composite was aged in the temperature range 300-550 ºC for 1-25 hrs. The age hardening behavior of composite then compared with that of binary Cu-2 wt. % Ti alloy. The microstructure of the composite was examined with highresolution transmission electron microscope (HRTEM). The results of this study showed that TiB 2 particles can act as heterogeneous nucleation site for '(Cu 4 Ti) precipitates. Substantial increase in tensile and yield stress of composite (i.e. 63% and 186%) occurred relative to the solution state, after ageing at 450 ºC for 10hrs. The maximum strength was associated with precipitation of metastable Cu 4 Ti near to the ultra hard TiB 2 particles within the matrix. However the mechanical properties of composite are comparable with Cu-2 wt. % Ti alloy , the maximum value of the hardness and electrical conductivity of composite (28 %IACS , 258 HV) and Cu-2 wt. % Ti (17% IACS , 264 HV) are obtained when solution treated samples were aged at 450 ºC for 10 hrs and 15hrs, respectively.
