Spot Friction Welding of Ultra High-Strength Automotive Sheet Steel
… (SFW) was performed on ultra high strength steel (UHSS) steel sheet commonly used in automobile manufacturing. Alloys studied included DP780, DP780EG, DP980, and DF140T sheet steel of varying thickness from 1.2 mm to 1.4 mm. Welding was accomplished using a PCBN standard tool. Weld strengths …

Design of an experiment to investigate the effects of electrode bearing area, weld-pressure, and current on the penetration and tensile-shear strength of resistance spot weldments in SAE CR 1010 sheet steel
The results of this investigation are based on the statistical and visual analyses of the data collected during this experiment

Strength of Arc Spot Welds Made in Single and Multiple Steel Sheets
… weld was formed in one-, two-, or four-layers of sheet steel ranging from 22 gauge (0.028 in.) to 16 gauge (.057 in.). Three distinct time series were tested for each unique weld size, thickness of sheet steel and layer configuration. The first of these series were the full-time welds. The two …

Strip with gradient properties by annealing in reactive atmospheres
Interstitial Free (IF) steels have excellent deep drawing capabilities and non-ageing properties. These steel grades still have some disadvantages such as a generally weak mechanical strength and high reactivity in the grain boundaries during galvannealing, which produces brittle …

In the Shadow of Steel: Leetonia, Ohio and Independent Iron Manufacturers in the Mahoning and Shenango Valleys, 1845-1920
… $2,000,000 charter application of the Leetonia Steel Company in March 1913. The McKeefrey family of Leetonia in partnership with Pittsburgh industrialists provided the impetus and initial financial backing for the proposed single-process sheet steel mill. Located in eastern Ohio, Leetonia’s once …

A novel method of detecting galling and other forms of catastrophic adhesion in tribotests
… duration of the tests. In the main study D2 tool steel annular specimens were tested on coldrolled sheet steel at 100 MPa contact pressure in flat sliding at 0.01 m/s. The effects of lubricant viscosity and lubricant chemistry on the adhesive properties of the surface were examined. Tests results …

Identification and Characterization of the Iron-Zinc Intermetallics Formed in Galvanneal steel
… demand to improve the corrosion resistance of steel sheet, particularly for use within the automotive industry, has led to a dramatic increase in the use of coated steels in place of cold-rolled sheet steel. Galvanneal steel results from the post annealing of the zinc-coated steel sheet, in …

THE STRENGTH OF BRAZED SINGLE-LAP JOINTS
… plate-fin heat exchangers, from low-cost stamped sheet steel which would be impossible to produce by traditional manufacturing techniques—except for metal 3D printing which is extremely slow and expensive. Specifically, stainless steel heat-exchangers brazed with Ni-based amorphous brazing foils …

Carbon Fiber Reinforced Polymer Retrofits to Increase the Flexural Capacity of Deteriorated Steel Members
… for corroded members include bolting or welding steel cover plates, replacing sections of the girder, or adding external prestressed tendons. However, these methods also have several challenges, including required lane closures, high installation costs, increased dead weight, and continuing …
