Warm forming of stainless steels - Part II

August 8, 2006 | By Ajay Yadav, Giovanni Spampinato, Taylan Altan, Ph.D.

The ERC/NSM conducted experiments using round cup tooling to determine the influence of temperature on the limiting draw ratio – the largest draw ratio of the blank-to-cup diameter that can be drawn successfully.

Warm forming of stainless steels - Part I

July 11, 2006 | By Ajay Yadav, Giovanni Spampinato, Taylan Altan, Ph.D.

To prevent martensitic transformation in stainless steel during drawing operations, warm forming has been explored. In experiments, warm forming eliminated intermediate annealing operations and substantially increased limiting draw ratio values.

Structured sheet metal - Part II

June 13, 2006 | By Michael Mirtsch, Ajay Yadav

Vault-structured sheet metal undergoes very little strain hardening during structuring, so it can be deformed further into shapes such as cans, containers, washing machine drums, thin-walled detector tubes, heat exchangers, and light reflectors.

Structured sheet metal - Part I

May 9, 2006 | By Michael Mirtsch, Ajay Yadav

Increasing sheet metal component rigidity while reducing weight can be achieved by substituting steel with aluminum, magnesium, or titanium alloys; advanced high-strength steel (AHSS); or 3-D structured sheet metal.
