Crystal model based on features, select the description Ta. w phase diagram of thermodynamic interaction equation, and determine which of the parameters. 2. Using a set of parameters describing disordered and ordered Ta. w alloy thermodynamics and explain disordered Ta. w solid solution more stable. References: [1] hrryKallfmsl1.
