As we continue to search for an increase in cooling rates, increasing pressure is only a partial answer. Increasing gas velocity might be the answer to the problem, because there are diminishing returns in cooling capacity by simply increasing quench-gas pressure.
The popularity of vacuum processing various materials continues to grow every day. The vacuum furnace is no longer a piece of equipment located in some remote corner of a shop, operating only when the need arises. As vacuum furnace suppliers continue to improve their gas cooling designs, metallurgists are afforded the opportunity to process a greater variety of materials in a vacuum furnace that might never have been envisioned even five years ago.
