Gas Quenching - an overview | ScienceDirect Topics

On quenching, bungs open on top and at the bottom of the hot zone, and the furnace is filled with the quench gas (nitrogen, helium, argon or hydrogen or mixtures of these gases) and pressurized to 5, 10 or 20 bar. A high powered fan and an efficient heat exchanger produce a strong gas flow through the load quenching it. Similar single chamber furnaces also exist as vertical furnaces either as ...

AIR QUENCHING OF ALUMINUM: THE AFFECT OF QUENCH ...

Air quenching is used as a means to limit the residual stresses as well as the brittleness that occurs during the quenching process. Rapid quenching also has a tendency to create distortions due to the stresses, especially if the cooling is non-uniform over the surface of the part, air quenching may be used to remedy this. For improving

QUENCHING MEDIA - tpub

QUENCHING MEDIA. The cooling rate of an object depends on many things. The size, composition, and initial temperature of the part and final properties are the deciding factors in selecting the quenching medium. A quenching medium must cool the metal at a rate rapid enough to produce the desired results. Mass affects quenching in that as the mass in­creases, the time required for complete ...

f - Fluidezed Bed Furnaces - G.E. Totten & Associates

Fluidized bed furnaces employ an alloy retort filled with sand-like alumina particles. When a controlled stream of air or gas is passed upward through a distributor below the retort, the particles float on a cushion of the air / gas stream and move around turbulently without elutriation. The now "fluidized" bed looks and behaves remarkably like a boiling liquid bath. When heated ...

Brine quench | BladeForums

04.03.2010 · Water quench. The smaller, so far, have not cracked, but I am getting cracks on some of the larger. All the cracks run with the grain, and are very fine, and not easy to see. I get one or two on each, and they go for maybe 3/8" long to 1/2". They appear to be shallow cracks, but can't say for sure. This one in the photo has two, but they don't show in the photo.

Hardening (metallurgy) - Wikipedia

The quenching is required since the material otherwise would start the precipitation already during the slow cooling. This type of precipitation results in few large particles rather than the, generally desired, profusion of small precipitates. Precipitation hardening is one of the most commonly used techniques for the hardening of metal alloys.

11: Heat Treating and Quenching Flashcards | .

Sand. Name and describe the four stages of quenching. 1. Vapor formation stage: the metal starts to cool. As soon as the metal is plunged in, the liquid making contact with the metal boils, forming a vapor film of bubbles that coat the metal. The cooling process slows down as this vapor film continues to form. 2. Vapor covering stage: the film of vapor continues to develop and acts as a ...

Quenching of Water-Reactive (WR) Materials

When quenching WR materials, the hazards of the mixture, the WR chemical and the solvent, should be considered together and procedures for safe quenching should reflect the hazard properties of both solvent and solute.
