High Strength Aluminum Alloy

Posted by Michael Pfeifer, Ph.D., P.E.

During our March 19, 2015 metallurgy question and answer webinar I answered the following question: What is needed to meet specs for solution treated and aged 7175 aluminum? This video recording shows my reply.

Sheet Metal Formability

Posted by Michael Pfeifer, Ph.D., P.E.

Formability refers to the ability of sheet metal to be formed into a desired shape without necking or cracking. Necking is localized thinning of the metal that is greater than the thinning of the surrounding metal. Necking precedes cracking.

From the metallurgical perspective, the formability of a particular metal depends on the metal’s elongation, which is the total amount of strain measured during tensile testing.

Controlling the Atoms in Metals

Posted by Michael Pfeifer, Ph.D., P.E.

On a microscopic level, there are many things going on inside of a metal. Metals consist of numerous microscopic structures that have a direct and large influence on the properties of metals. Through composition, mechanical treatment, and thermal treatment these microscopic structures can be modified to impart specific properties. Whether the desired structures, and resulting properties, are obtained in a completed component or joint between components depends on the knowledge and skill of designers and manufacturers.

Phase Transformations in Alloys

Posted by Michael Pfeifer, Ph.D., P.E.

The metallurgical phases present in an alloy have a huge impact on the properties of a metal component. Phases are distinct materials that are comprised of the elements in the alloy. These distinct materials have distinct properties that have an impact on the overall properties of the entire alloy. Additionally, the size, shape, and location of the phases within the alloy also effect on the overall properties of an alloy. Within many common alloys it is possible to alter the phases present with heat treatment.

The Relationship Between Metal Properties, Composition, Microstructure, and Manufacturing Processes

Posted by Michael Pfeifer, Ph.D., P.E.

This short video lesson explains the relationship between the properties of a metal and the metal's composition, microstructure, and the manufacturing processes used to fabricate a component or form a joint between components. It's an example of the format used for our metallurgy courses.
