    • Al-Co, Co-Fe Diffusion Mobilities, Ni/Rene88, IN718/Rene88 

      Campbell, Carelyn E.; Zhao, J-C.; Henry, M. F. (2013-05-05)
      A multicomponent diffusion mobility database for the Ni-rich fcc phase [2002Cam] is evaluated by comparing diffusion simulations to two experimental multicomponent Ni-base superalloy diffusion couples: Ni/Rene´-88 and ...
    • Al-Co-W 900C Phase Equilibria Data 

      Lass, Eric; Maureen E. Williams; Carelyn E. Campbell; Kil-Won Moon; Ursula R. Kattner (2014-09-03)
      Phase equilibria at 900 °C in the Co-rich Co-Al-W ternary system are investigated through isothermal annealing of six alloy compositions for times up to 8000 h. The volume fraction of the L12-γ′ phase co-existing with ...
    • Co-Al-W Diffusion Mobilities 

      Moon, Kil-Won; Campbell, Carelyn; Williams, Maureen; Boettinger, William (2016-04)
      Diffusion couple experiments between various Co-rich face centered cubic (FCC) alloys in the Co-W-Al ternary system have been conducted at 900 °C and 1000 °C. Diffusion coefficients have been extracted for the Co-W binary ...
    • Experimental Investigation and Thermodynamic Modeling of the Co-Rich Region in the Co-Al-Ni-W Quaternary System 

      Zhu, Jun; Titus, Michael S; Pollock, Tresa M (2017-03-20)
      The stabilities of the γ-(Co), γ′-Co3(Al,W), μ-Co7W6, β-CoAl and α-(W) phases in the Co-Al-W and Ni-Al-W ternary systems were investigated at 900, 1000, 1100 and 1300 °C. Electron probe microanalysis was used to determine ...
    • Thermodynamic Description of the Ti-Al-O System Based on Experimental Data 

      Ilatovskaia, Mariia; Savinykh, Galina; Fabrichnaya, Olga (2017-06-08)
      Phase equilibria of the TiO2-Al2O3 system were investigated experimentally using XRD, SEM/EDX and DTA methods. Temperature stability limits of the aluminum titanate (Al2TiO5) were detected. The thermodynamic parameters of ...
    • Interdiffusion in the Ni-Re System: Evaluation of Uncertainties 

      Boettinger, William J; Williams, Maureen E; Moon, Kil-Won; McFadden, Geoffrey B; Patrone, Paul N; Perepezko, John H (2017-06-22)
      Diffusion couple experiments between Ni and Re at 1200 and 1350 °C were performed. These experiments established the limits of the two-phase FCC + HCP region. No intermediate phase was observed at these temperatures. ...
