Introduction
Background of Standard Revision and Technological Evolution
As the core standard in the field of beryllium sheet manufacturing, YS/T 41-2005 has upgraded 7 key technologies compared with the 1992 version:
| Revisions | 1992 Edition | 2005 Edition | Technical Significance |
|---|---|---|---|
| Thickness Range | 0.1-3.0mm | 0.02-1.5mm | Expanded Ultra-Thin Sheet Processing Capability |
| BeO Content | ≤2.0% | ≤1.5% | Improve material purity |
| Inspection indicators | Not specified | Add vacuum air tightness test | Strengthen quality control |
Analysis of core technical requirements
1. Product classification system
The standard divides beryllium sheets into three categories:
- Circular sheets: diameter ≤100mm, thickness 0.02-1.5mm
- Rectangular sheets: maximum length of 200mm, with finer thickness classification
- New semicircular ring sheets: arc length ≤270°, filling the gap in special shapes
2. Key Performance Indicators
Typical Case: Beryllium windows for nuclear industry must meet the following requirements:
- Density ≥ 1.84 g/cm³ (GJB 2513 test)
- Leakage rate of 0.1 mm thick sheet ≤ 3×10-7 Pa·L/s
- When Be content ≥ 98%, impurity Fe must be ≤ 0.1%
Implementation points and testing specifications
1. Dimension Control Matrix
| Type | Thickness tolerance | Typical application |
|---|---|---|
| Ultra-thin sheet (0.02-0.05mm) | ±0.005mm | Radiation window |
| Conventional sheet (0.5-1.5mm) | ±0.05-0.10mm | Structural parts |
2. Inspection frequency requirements
- Full inspection items: Surface quality (cracks/black spots)
- Sampling inspection: 100% airtightness inspection for sheets with thickness <0.1mm
- Batch inspection: Density test 2-3 specimens per batch
Special process precautions
For Vacuum hot pressing process:
- The BeO content of the blank needs to be controlled before sintering
- Cold pressing and sintering needs to ensure a theoretical density of 1.84g/cm³
- Ultra-thin sheet rolling needs to control the roller temperature at ±5℃
