Field Assisted Sintering Technique (FAST), also known as Spark Plasma Sintering (SPS), is a rapid sintering method.
It utilizes a DC electric current to directly heat the material.
This significantly reduces processing times.
It allows for the production of materials with high densities and controlled microstructures.
4 Key Benefits of Field Assisted Sintering Technique (FAST)
1. Direct Heating Mechanism
FAST/SPS employs a DC electric current that directly heats the mold and/or the sample through Joule heating.
This direct heating method is more efficient than indirect heating methods used in traditional sintering.
The direct application of electric current allows for precise control over the temperature and heating rate.
This can be significantly higher than those achievable with conventional methods.
This rapid heating accelerates the diffusion of atoms across particle boundaries.
Leading to faster densification and shorter processing times.
2. Lower Temperatures and Pressures
Compared to conventional hot pressing and sintering techniques, FAST/SPS typically operates at lower temperatures and requires less pressure to achieve high-density materials.
This is advantageous as it reduces the risk of grain growth and other undesirable microstructural changes that can occur at high temperatures.
The lower operating temperatures also contribute to energy savings and extend the range of materials that can be processed without degradation.
3. Manufacturing of High-Performance Materials
The FAST/SPS technique opens up new possibilities for the manufacture of materials with potentially extraordinary characteristics.
It is particularly useful for synthesizing materials with controlled microstructures.
This is crucial for achieving specific mechanical, electrical, or thermal properties.
The ability to sinter materials at near-theoretical densities without significant grain growth makes it an invaluable tool for producing advanced materials such as ceramics, metals, and composites.
4. Comparison with Conventional Sintering
While conventional sintering methods can be time-consuming and often require high temperatures and pressures, FAST/SPS can achieve similar or better results in a fraction of the time.
The use of electric current in FAST/SPS not only speeds up the sintering process but also allows for the production of complex shapes and near-net-shape parts.
This is challenging with traditional sintering methods.
