# Industrial Specification: High-Purity Ferrovanadium Master Alloy

## 1. Technical Definition
A master alloy of iron and vanadium used as a grain refiner and strengthening agent in steel production.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **1550-1650°C melting temperature, 7.0-7.5 g/cm³ density, 0.5-2.0 wt% vanadium content**. Failure boundary: **Vanadium content below 0.3 wt% causes insufficient grain refinement, above 2.5 wt% leads to embrittlement; temperature exceeding 1700°C initiates excessive oxidation with 15% mass loss threshold**, Mechanism: **Vanadium carbide precipitation at grain boundaries (VC formation with 0.77 nm lattice parameter) controls strengthening; oxidation follows parabolic rate law with activation energy 180 kJ/mol above 1700°C**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.
