中文 FAST Hybrid technology
Type H-HP D - hybrid heated
Description
"Hybrid heating" is the combination of the FAST/SPS process with one or more heating systems, that normally influence the press tool systems from the outside. The thermal gradients of a standard FAST/SPS system, which are typically directed from the inside to the outside, can thus be compensated by the inversely directed gradients of the additional heating system. This further improves heating rates while optimising homogeneity and providing all the benefits mentioned above.
Hybrid technology is particularly advantageous for avoiding radial temperature gradients in large-format components or materials that are not sufficiently conductive.
Nanomaterials can be sintered without significant grain growth
