ASTM E228 Coefficient of Thermal Expansion for AM Alloys
The ASTM E228 standard is a critical tool in material testing, particularly when dealing with the additive manufacturing (AM) process. This standard allows us to determine the coefficient of thermal expansion (CTE), which is essential in ensuring that materials used in AM processes perform reliably under varying temperatures.
Understanding CTE is crucial because it affects how materials behave during and after the AM process. Variations in temperature can cause stress, deformation, or even failure if not properly accounted for. This is particularly important when selecting alloys for AM applications as different metals have different thermal expansion properties.
The ASTM E228 method involves precise measurement using dilatometric techniques, which are capable of detecting very small changes in length as a material expands and contracts due to temperature change. The process typically includes the following steps:
- Selection of appropriate alloy specimens
- Preparation of specimens according to ASTM E228 specifications
- Placement of specimens in a dilatometer
- Heating and cooling cycles at controlled rates
- Data recording and analysis
The precision of these measurements is paramount as even minor discrepancies can lead to significant errors. Our laboratory ensures that all tests adhere strictly to ASTM E228 standards, providing accurate and reliable results.
Our team of experts works closely with customers to ensure that the correct alloys are chosen for AM applications based on their CTE values. This collaboration allows us to tailor our services to meet specific project requirements, ensuring that the materials used in manufacturing processes will perform as expected under various thermal conditions.
Scope and Methodology
| Step | Description |
|---|---|
| 1. Specimen Preparation | The specimens are prepared according to ASTM E228, ensuring they meet the required dimensions and properties. |
| 2. Dilatometric Measurement | This involves heating and cooling the specimen in a dilatometer while recording its length changes. |
| 3. Data Analysis | The recorded data is analyzed to determine the coefficient of thermal expansion. |
The ASTM E228 method ensures that we can provide accurate and reliable CTE values for various AM alloys, which is essential for quality assurance in manufacturing processes. By adhering strictly to this standard, we ensure consistency and repeatability of results.
