A vacuum furnace is a type of furnace that can heat materials – typically metals – to very high temperatures and carry out processes such as brazing, sintering and heat treatment with high consistency and low contamination. This course looks at the trends, applications and general process of vacuum heat treatment to show how it works and why it has become a favored technology.

Advantages of Vacuum Heat Treatment for Tool Steels Part 1
The heat treatment of tool steels (and any other steel heat-treatment procedure) relies on a given set of metallurgical principles. This article looks at the technology processes that vacuum heat treatment makes possible.

Advantages of Vacuum Heat Treatment for Tool Steels Part 2
The heat treatment of tool steels (and any other steel heat-treatment procedure) relies on a given set of metallurgical principles. The second part of this article looks at how vacuum heat treatment has advantages for hot-work tools such as forging dies, shot sleeves, aluminum die-casting dies, magnesium die-casting dies and other hot-work applications.

Distortion: Causes and Effects
As every heat treater – captive or commercial – knows, distortion will occur. The heat treater must recognize the many reasons why distortion occurs. This applies to both ferrous and nonferrous materials. This article looks at the steps to reduce it.

Technology Trends in Vacuum Heat Treating: Processes and Applications
Vacuum thermal processing is vital for automotive and aerospace component manufacturers due to industry demands for the highest possible quality. Brazing and surface treatment are two process areas where vacuum technology is used.

Midcentury-Modern Heat Treatment
By the end of the decade of the 1960s, vacuum oil-quenching furnaces were being used commercially, and improvements in vacuum-coating and brazing processes were also being made. This article summarizes heat-treatment history from 1950 to the 1990s, including vacuum furnace processes.

Carburizing Q&A with the Heat Treat Doctor (part 2)
There are 183 chemical reactions taking place inside a carburizing furnace. Of all those chemical reactions, the water-gas reaction is the most important. This Q&A with the Heat Treat Doctor looks at the ins and outs of carburizing, including vacuum carburizing.
