Principles For Understanding Heat Treating Steel And Aluminum: Brazing (Part 1)

Principles for Understanding Heat Treating Steel and Aluminum: Brazing (Part 1)

The process of brazing involves the use of a molten filler metal to wet the mating surfaces of a joint by capillary action, with or without a fluxing agent, leading to the formation of metallurgical bonds between the filler and respective components.  The reactions which occur between the molten filler and surfaces of the solid components result in solutionization, which is erosion of the solid phase by the molten filler alloy.  However, this solutionization reaction is localized to the surface…

Principles For Understanding Heat Treating Steel & Aluminum: Age Hardening

Principles for Understanding Heat Treating Steel & Aluminum: Age Hardening

Until now, the articles in this series have dealt primarily with the thermodynamic principles and basis for materials processing as applies to heat treating steel and aluminum.  In this article we will delve into the practical application of age hardening, a phase transition in materials science formally referred to as precipitation hardening. Background The technique of age hardening evolved from the original observations of the German metallurgist Alfred Wilm in the early 1900s.  Wilm conducted a series of experiments in…

Principles For Understanding Heat Treating Steel And Aluminum: The Ellingham Diagram (Part 2)

Principles for Understanding Heat Treating Steel and Aluminum: The Ellingham Diagram (Part 2)

Previously, I introduced the fundamental precepts that define the construction of the Ellingham diagram, which is based on the Gibbs free energy at standard state conditions (ΔGo) for a metal oxidation reaction.  Now we move on to a more detailed look at how the Ellingham diagram can be utilized in practical situations.  These are all important principles to understand heat treating steel and aluminum. Practical Applications of the Ellingham Diagram Figure 1 is a modern version of the Ellingham diagram,…

Principles for Understanding Heat Treating Materials: The Ellingham Diagram (Part 1)

by Mike Powers, F.A.S.M.   In the previous article of this series, we investigated the wetting of solids by liquids in terms of the Young Equation.  Now we turn to one of the most utilitarian tools in thermodynamics and materials processing, the Ellingham diagram.  I feel it is only fair to start off with a brief discussion about the man behind the diagram.  Harry Ellingham was a British physical chemist, best known for his Ellingham diagrams, which summarize the empirically…
