# Industrial Specification: Turbine Housing

## 1. Technical Definition
The outer casing that contains and directs exhaust gases to drive the turbine wheel in a turbocharger.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-15 bar pressure differential, 600-950°C continuous gas temperature, 0.05-0.15 mm radial clearance to turbine wheel**. Failure boundary: **Material yield strength exceeded at 18 bar pressure differential, creep rupture at 1050°C for 1000 hours, thermal fatigue cracking at 10000 thermal cycles from 200°C to 900°C**, Mechanism: **Thermal fatigue from cyclic temperature gradients exceeding material's ΔT_limit of 700°C, causing crack initiation at stress concentrations; creep deformation from sustained operation above 0.4×Tm (where Tm=melting temperature)**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

- **Caution**: 

### Q: What materials are best for turbine housing in high-performance vehicles?
**A**: Nickel-based superalloys and austenitic stainless steel offer superior heat resistance and durability for high-performance applications, while cast iron provides cost-effective reliability for standard vehicles.

### Q: How does the turbine housing design affect turbocharger efficiency?
**A**: The volute shape and flange designs optimize exhaust gas flow to the turbine wheel, reducing turbo lag and improving overall engine performance and fuel efficiency.

### Q: What maintenance is required for turbine housings?
**A**: Regular inspection for heat cracks, corrosion, and proper wastegate function is essential. Most housings require minimal maintenance when using appropriate materials for operating conditions.

## 6. Manufacturing Compliance
