R&D Update: Heat generation in forming of AHSS
- By Ali Fallahiarezoodar, Ruzgar Peker, and Taylan Altan, Ph.D.
- Mar 10, 2015
- Bending and Forming
- Article
Advanced high-strength steel (AHSS) materials are multiphase steels that contain martensite, bainite, and/or retained austenite. The use of AHSS materials in the automotive industry is increasing every day, because these steels provide strength and satisfy functional requirements at reduced weight....

R&D Update: Examining lubricant performance in forming of AHSS
- By Ali Fallahiarezoodar, Taylan Altan, Ph.D., and Suraj Appachu
- Feb 5, 2015
- Bending and Forming
- Article
Lubrication plays an important role in stamping, as it reduces friction at the tool-workpiece interface. Reducing that friction also reduces die and tool wear in large-volume production, which in turn increases tool life. It also allows smoother flow of the sheet material into the die cavity and...

R&D Update: Warm forming of alloys in the auto industry
- By Eren Billur and Taylan Altan, Ph.D.
- Jun 28, 2013
- Bending and Forming
- Article
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.

R&D Update: Lubrication and galling in stamping of galvanized AHSS - Part III
- By Taylan Altan, Ph.D.
- Apr 15, 2008
- Bending and Forming
- Article
Forming of galvanized AHSS involves higher contact pressures at the tool-workpiece interface compared to forming mild steel. Under these severe interface conditions, improper selection of lubricants, tool materials and tool coatings may result in high scrap rates and galling in stamping production.. Based on SDT results, polymer-based lubricant with EP additives and water-soluble DFL were found to be most effective, Synthetic lubricants showed also reasonably small frictional responses with a PVD coated die in forming GA coated strips.

Blanking developments - Part III
- By Serhat Kaya and Taylan Altan, Ph.D.
- Sep 11, 2007
- Bending and Forming
- Article
During high-speed blanking, press stroking rate and punch speeds, are higher than in conventional blanking. As a result, the shear zone has a higher strain rate, which affects a workpiece's sheared surface temperature and the tool surface.

- Bending and Forming
- Article
Global competition continues to force the metal forming industry to reduce costs, improve technology, and increase productivity. With these trends in mind, the Ohio State University (OSU) and Virginia Commonwealth University (VCU) established in June 2006 the Center for Precision Forming to focus on the needs of the metal forming industry.

Servo press forming applications
- By Taylan Altan, Ph.D.
- May 8, 2007
- Bending and Forming
- Article
A servomotor gives a press slide motion flexibility in terms of accurate speed, motion, and position control. This flexibility produces infinite slide motion variations that may improve part quality and operations such as painting and assembly during one press stroke.
