    • Ag-rich precipitates formation in the Cu-11%Al-10%Mn-3%Ag alloy 

      Silva, R. A. G. [UNIFESP]; Paganotti, A. [UNIFESP]; Jabase, L. [UNIFESP]; Adorno, A. T.; Carvalho, T. M.; Santos, C. M. A. (Elsevier B.V., 2014-12-05)
      The formation of Ag-rich precipitates in the Cu-11%Al-10%Mn-3%Ag alloy initially quenched from 1123 K was analyzed. the results showed that nanoprecipitates of a Cu-rich phase are produced at about 523 K. in higher ...

    • Bainitic precipitation in the Cu-9 wt.%Al-4 wt.%Mn-5 wt.%Ag alloy 

      Adorno, A. T.; Carvalho, T. M.; Magdalena, A. G.; Santos, C. M. A. dos; Silva, R. A. G. [UNIFESP] (Elsevier B.V., 2014-12-05)
      The isothermal kinetics of bainitic precipitation in the Cu-9 wt.%Al-4 wt.%Mn-5 wt.%Ag alloy was studied in the temperature range from 250 to 400 degrees C. the results indicated a diffusion controlled growth process with ...

    • Effect of Ag addition on phase transitions of the Cu-22.26 at.%Al-9.93 at.%Mn alloy 

      Silva, R. A. G. [UNIFESP]; Gama, S. [UNIFESP]; Paganotti, A. [UNIFESP]; Adorno, A. T.; Carvalho, T. M.; Santos, C. M. A. (Elsevier B.V., 2013-02-20)
      The phase transitions that occur in the Cu-22.26 at.%Al-9.93 at.%Mn and Cu-22.49 at.%Al-10.01 at.%Mn-1.53 at.%Ag alloys after slow cooling were studied using differential scanning calorimetry at different heating rates, ...
