Fields

theoretical_density: f64

Material density of the fully dense material (kg/m³).

e_low: f64

Lower bound energy density for good densification (J/m³).

e_high: f64

Upper bound energy density before keyhole formation (J/m³).

hardness_full_dense: f64

Vickers hardness at theoretical density (HV).

hall_petch_k: f64

Fitted Hall–Petch coefficient (HV·m^0.5).

grain_size_opt: f64

Grain size at optimal energy density (m).

Implementations

impl ProcessWindow

pub fn new( theoretical_density: f64, e_low: f64, e_high: f64, hardness_full_dense: f64, hall_petch_k: f64, grain_size_opt: f64, ) -> Self

Construct a ProcessWindow.

pub fn relative_density(&self, energy_density: f64) -> f64

Predicted relative density (0–1) as a function of energy_density (J/m³).

Uses a sigmoidal model: ρ_rel = 1 / (1 + exp(−k · (E − E_mid))).

pub fn hardness_prediction(&self, energy_density: f64, grain_size: f64) -> f64

Predicted Vickers hardness at a given energy_density (J/m³).

Combines density-based degradation with a Hall–Petch grain-size term.

pub fn is_in_window(&self, energy_density: f64) -> bool

True if energy_density lies within the acceptable process window.

pub fn window_width(&self) -> f64

Window width in J/m³.
