high temperature vacuum sintering furnace
Key words:
In modern materials science, nanocrystalline metallic materials are widely used in aerospace, electronic devices, biomedical and other fields due to their excellent mechanical properties, high strength and unique physicochemical properties. However, the properties of nanocrystalline materials are highly dependent on their microstructures, and the cooling rate during the sintering process is one of the key factors affecting the grain size, densities and residual stresses.
Key words:
Thirty years ago, high-temperature vacuum sintering technology was still an exclusive process for the metallurgical industry, mainly used for the preparation of traditional materials such as cemented carbide and special ceramics. And today, it has become one of the core technologies in aerospace, electronic devices, biomedical, 3D printing and other high-end manufacturing fields. From traditional metallurgy to modern additive manufacturing (3D printing), high temperature vacuum sintering technology has experienced what kind of change? How will it develop in the future?
Key words:
In the field of materials preparation, high-temperature vacuum sintering furnaces are widely recognized as ideal equipment for obtaining high-purity materials. However, even with a high vacuum environment of 10-⁴ Pa, a variety of contaminants may still be generated in the furnace, leading to degradation of material properties and shortening of equipment life. Where do these contaminants come from? And how can they be effectively suppressed? In this paper, we will analyze this key issue, which has been overlooked by many practitioners.
