Evolution of Strain-Induced Microstructure and Texture in Commercial Aluminum Sheet Under Balanced Biaxial Stretching

March 1, 2003

Author(s)

Stephen W. Banovic, Timothy J. Foecke

The evoluation of surface topography and crystallographic texture was investigated under balanced biaxial stretching in sheets of aluminum alloy 5052 H32. Two different lots of material, with initial nominal thickness of 1 mm, were tested in the as

Material Model for Strain-Induced Surface Roughening of Sheet Metal

May 1, 2002

Author(s)

Y Shim, Mark R. Stoudt, Lyle E. Levine, Stephen W. Banovic, Richard J. Fields

A generic model for strain-induced surface roughening has been derived from a statistical analysis of experimental data from aluminum alloys. The model predicts the surface roughening in sheet metal as a function of strain and grain size. Our analyses

The Effect of Microstructural Variables on the Surface Roughening of 5XXX Series Aluminum Sheet in Biaxial Tension

March 1, 2002

Author(s)

Stephen W. Banovic, Timothy J. Foecke

The investigation into reducing overall vehicle weight by replacing conventional steel sheet metal with lightweight materials has been initiated. However, implementation of these lightweight alloys, specifically those that are Al-base, has been slow due to

Development of Strain Induced Surface Topography of 6XXX Series Aluminum Sheet Under Balanced Biaxial Tension

February 1, 2002

Author(s)

Stephen W. Banovic, Timothy J. Foecke

With gas mileage goals set down in the Partnership for a New Generation of Vehicles as a driving force, the investigation into reducing overall vehicle weight by replacing conventional steel sheet metal with lightweight materials has been initiated

Correlations of Texture and Roughening During In-Plane Balanced Biaxial Straining in 5XXX-Series Aluminum Alloys

January 1, 2002

Author(s)

Timothy J. Foecke, Stephen W. Banovic

Using a modified Marciniak biaxial stretching test, we are able to produce large samples with uniform amounts of balanced biaxial strain. The sheets were fully characterized at various strain levels, measuring texture using x-ray rocking curve analysis and

Dilution control in Gas-tungsten arc welds involving superaustenitic stainless steels and nickel-based alloys

December 1, 2001

Author(s)

Stephen W. Banovic, J N. DuPont, A R. Marder

Dissimilar metal welds were prepared between a super austenitic stainless steel, AL-6XN alloy, and two Ni-base filler metals, IN625 and IN622, using the Gas Tungsten Arc Welding (GTAW) process. Fusion zone compositions over the full range of dilution

Sheet Metal Formability Studies at the National Institute of Standards and Technology

February 1, 2001

Author(s)

Timothy J. Foecke, Stephen W. Banovic, Richard J. Fields

Sheet metal forming is a multi $10-billion industry in the United States, with an overwhelming portion of its use in the automotive industry as formed sheet components. In order to reduce the overall weight of a vehicle, the Big 3 are trying to move to

Corrosion Behavior of Weldable Fe-Al Alloys in Oxidizing-Sulfidizing Environments

January 1, 2001

Author(s)

Stephen W. Banovic, J N. DuPont, A R. Marder

Weld overlay coatings are typically used to protect existing low alloy steel water-wall panels from accelerated sulfidation attack in fossil-fired boilers with advanced low NO x burners. A material system presently under consideration for use as a cladding
