In the final installment of this three-part series, Bill Jones expresses his vision for the future of hot-zone designs and other considerations in the advancement of vacuum furnace technology.

In this second in a series of three podcasts, an industry pioneer on the forefront of modern furnace technology reviews the present state-of-the-art of hot-zone innovations.

The first in a series of three podcasts looks back over the evolutionary history of hot-zone designs from the beginning of the modern vacuum furnace and discusses a few important developments that helped to shape present-day furnace technology.

This installment provides an overview of reactive brazing in a vacuum furnace and the use of active brazing alloys for successful results in joining titanium and titanium alloys.

This installment is the second in our series on vacuum furnace brazing. The discussion centers on the advantages and concerns of brazing of stainless steel components with nickel-based and copper-based brazing alloys.

This podcast is the first in a series on vacuum furnace brazing. It is an overview of the different types of brazing processes and why vacuum furnace brazing is superior to other joining methods, particularly torch brazing and welding.

Distortion and cracking of parts is a common problem for heat treaters. This podcast is a discussion on how to prevent and reduce the distortion and cracking of tool steels and other ferrous alloys when cooling parts in a gas-quenching vacuum furnace.

This podcast features a discussion on how contaminants develop on ceramic insulators, how contamination affects the operation and performance of a vacuum furnace, and how to keep ceramic insulators clean of contaminants.

A discussion on the importance of measuring and monitoring the trace levels of dew point (water vapor), oxygen and other gases to reduce part contamination through the use of a residual gas analyzer for in-process vacuum analysis, research and development, and maintenance.

This month’s podcast is Part 1 on the importance of measuring and monitoring the trace levels of dew point and oxygen in quench gases to reduce part contamination while processing in a vacuum furnace.
