Aluminum Alloys
What are the 3 most common aluminum alloy series we see?
6000 series, 7000 series, 2000 series
This heat treatment process increases steel’s hardness by rapidly cooling it from a high temperature.
Quenching
This nickel-based superalloy, known for its creep resistance, is commonly heat-treated for turbine blades.
Inconel
Vacuum heat treatment prevents this unwanted reaction between the metal surface and atmospheric gases.
Oxidation
This aluminum temper designation indicates that the alloy has been solution heat-treated and artificially aged.
T6
This heat treatment process strengthens aluminum alloys by forming precipitates within the metal’s structure.
What is precipitation hardening (or aging)?
This heat treatment process makes steel softer and easier to shape by heating and slowly cooling it.
Annealing
This heat treatment step for nickel alloys dissolves secondary phases to prepare the material for aging.
Solution Annealing
This gas is often used to quench parts in a vacuum furnace, providing rapid cooling without contamination.
Nitrogen
This process takes place after solution and quenching and typically takes up to 96 hours to complete
Naturally Aging
This alloy, often used in aerospace, is a high-strength 7000-series aluminum alloy with zinc as its primary alloying element.
7075
This is the term for when parts stick together after heat treat
Sintering
The aging process for Inconel 718 is most commonly completed by using these 2 temperatures
Vacuum furnaces maintain pressure below this level, typically measured in torr, to ensure a clean environment.
1x10-3
Name 3 of Hy-Vac's most common casting alloys
356/A356/A357/C355
During solution heat treatment of aluminum, the alloy is heated to this temperature range to dissolve soluble phases.
870F-1000F
This metal, added to steel, helps it resist rust and is common in precipitation-hardenable alloys.
Chromium
Inconel 625 is a non-hardenable grade of nickel alloy, what process can be done to it?
Solution Annealing
This customer requires 2 thermocouples in all vacuum processing.
General Electric
Hardness and Conductivity
During high temperature processing of aluminum, if the alloy is over heated this happens
Eutectic Melting
Steel is a mix of iron and this element that makes it harder.
Carbon
This element, often mixed with nickel, makes alloys harder and is also used in blue paint.
Cobalt
Inside of a vacuum furnace, the elements are made of this material
Molybdenum
During the Solution step of aluminum, when there is an interruption in the process - what must be done?
Restart the process from the very beginning.
