# Industrial Specification: Forging-Grade Copper Alloy Billet

## 1. Technical Definition
Semi-finished copper alloy stock for hot forging operations

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **750-950°C forging temperature, 0.5-2.0 m/s strain rate, 30-70% reduction per forging pass**. Failure boundary: **Grain growth beyond ASTM 5.0 grain size number at 1000°C, hot shortness at 0.8Tm (680°C for Cu-2%Be), incipient melting at 1083°C**, Mechanism: **Dynamic recrystallization failure due to Zener-Hollomon parameter exceeding 1e15 s⁻¹, causing abnormal grain growth and reduced forgeability**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
