AMS 2750 pyrometric requirements for heat treatments: what's new in revision F

AMS 2750 (Aerospace Material Specifications) is an aerospace international specification which covers the pyrometric requirements for plants used for the heat treatment of metallic materials. Specifically, it covers temperature sensors, instrumentation, plant equipment, correction factors and offsets of instruments, system accuracy testing and temperature uniformity testing. These are necessary to ensure heat treatment of parts or raw materials in accordance with applicable specifications.

The AMS 2750 is now in revision F, was revision E from July 2012.

Let's see what’s new.

Vacuum brazing: the guide to perfect brazed joints

When the importance of producing a perfect brazed joint is uppermost, vacuum brazing is a highly effective method of joining two parts. Due to the nature of the vacuum, heat is evenly distributed and part production is consistent. Brazing requires three components: two parent metal pieces and a filler to join them. In the furnace, the components are arranged so that the filler will melt and flow on the base pieces, and join them solidly when cooled. Vacuum brazing provides strength, durability, and reliability unmatched by other metal joining methods. It also requires no secondary fabrication or finishing.

Hot-wall vs cold-wall vacuum furnaces: which one to choose

The demands of heat treatment industry are for higher temperatures, lower pressures, rapid heating and cooling capabilities, and higher production rates.  This has inevitably led to the use of so-called “cold-wall” vacuum furnaces, to the detriment of hot-wall furnaces, which are now considered obsolete. So, let’s see hot-wall and cold-wall furnaces - what could these be and how do they differ from each other?
