- linearExpansion(Tk=None, Tc=None)[source]
Returns instantaneous coefficient of thermal expansion of Alloy 200.
- setDefaultMassFracs()[source]
Notes
It is assumed half the max composition for the impurities and the rest is Ni.
- density(Tk: float = None, Tc: float = None) float
Return density that preserves mass when thermally expanded in 3D (in g/cm^3).
Notes
Since refDens is specified at the material-dep reference case, we don’t need to specify the reference temperature. It is already consistent with linearExpansion Percent. - p*(dp/p(T) + 1) =p*( p + dp(T) )/p = p + dp(T) = p(T) - dp/p = (1-(1 + dL/L)**3)/(1 + dL/L)**3
