Springback comparison between DP600 and DP800 steel grades

Numerical and Experimental Investigations on Springback of U-bending of DP600 Steel Alloy Sheet

The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...

Classification of Rust Grades on Steel Surfaces

Selecting most representative features among a huge feature set is considered in this paper. One feature extraction and five feature selection algorithms are tested on features obtained form steel surfaces. Two new feature selection algorithms are introduced in this paper. Performance measure for feature selection algorithms is also introduced as a new method to select the best performing featu...

Analysis of welding in comparable steel grades

Characterization of Microstructure and Mechanical Properties of Resistance Spot Welded DP600 Steel

Resistance spot welding (RSW) as a predominant welding technique used for joining steels in automotive applications needs to be studied carefully in order to improve the mechanical properties of the spot welds. The objectives of the present work are to characterize the resistance spot weldment of DP600 sheet steels. The mechanical properties of the welded joints were evaluated using tensile-she...

alloy steel: significance, grades and applications

alloy steel, which is versatile in such qualities as grade, property and application, can play an important role in the technical and economic development of the country. the present consumption of the key industrial sector to this strategic material, specified basically as semi- finished products exceeds 100,000 tons per year. however, a rough estimation of the true potential needs, does clear...
