This is the 13th article in our Vacuum Heat-Treatment Series. What follows is a discussion of cleaning, one of the most important subjects in vacuum processing. When vacuum furnaces were first introduced, many in the industry felt that the only acceptable part and fixture cleaning method was solvent vapor decreasing. Over the years, however, environmental and other factors have necessitated the use of aqueous systems. Therefore, it is important to understand how each method can successfully get the job done.

Next Time: Part 14 of this series discusses diffusion bonding, eutectic melting, outgassing and other topics related to what can go wrong inside the vacuum furnace as we process parts.

| Liquation of Brazing Filler Metals - Good or Bad? | by Dan Kay | When a brazing filler metal (BFM) is melted during a brazing process, it is not uncommon for "liquation" to occur.
|
 |
Liquation in brazing is defined as the tendency of the lower-melting constituents of a BFM to separate out and flow away (by capillary action) from the higher-melting constituents of the BFM during heating. Sometimes a non-melted "skull" of alloy remains at the point where the BFM was applied. Liquation is usually apparent in BFMs having a wide melting range, i.e. having a large difference between the solidus and liquidus (Note 1) temperatures. It occurs when the BFM is heated slowly through that melting range (such as when furnace brazing). Read more >> |
Kay & Associates Brazing Seminars cover all the essentials for successful brazing of commercial and aerospace components. NEXT PROGRAM: Greenville, SC - October 5-7, 2010. Click here for more information.

| Who is the Nadcap Auditor? | ||
| by Arshad Hafeez | ||
Aerospace thermal processing and Nadcap go hand in hand. Nadcap auditors are your key interface. Who are these people, and how can they help you? This article answers these questions and more.

 |
Many Industrial Heating readers are familiar with the Nadcap program. In fact, nearly a quarter of respondents to a recent Industrial Heating online poll indicated that they are Nadcap accredited. In the same poll, over 40% indicated that they comply with AMS 2750D (Pyrometry), compliance with which is required to achieve Nadcap heat-treating (AC7102) accreditation. |
