Alloys (CALPHAD & HEA)

Screening & design

screen_compositions ranks compositions against yield strength / density / cost; hea_stability scores solid-solution vs intermetallic risk from Miedema enthalpies, VEC, delta and Omega; design_alloy hill-climbs toward targets under a cost budget.

CALPHAD

Real pycalphad phase boundaries and Scheil solidification against a vendored TDB when available, else an honestly-labelled regular-solution fallback. Density/cost are COMPUTED; yield strength is an empirical rule labelled PREDICTED.

Terminology

HEA (5+ principal elements), VEC, atomic-size mismatch, Omega parameter, Miedema enthalpy, Scheil solidification.
