R&D Update: Warm forming of alloys in the auto industry

June 28, 2013 | By Eren Billur, Taylan Altan, Ph.D.

While stampers struggle with traditional forming of aluminum alloys, particularly in the automotive industry, they should know that research is currently underway to make this tough job easier. Warm forming of certain aluminum alloys is a real possibility when it comes to stamping parts from these difficult-to-work-with materials.

Die materials and wear in stamping AHSS

January 9, 2010 | By Eren Billur

Advanced high-strength steels (AHSS) are used extensively in the automotive industry to help improve crash safety and reduce weight. With the increased strength of AHSS, however, come dramatically increased springback and forming load (and, therefore, contact pressure) compared to milder steel grades.
