Changing the Hardness Automotive Steels at Different Strain Rate

Abstract

Currently, the automotive industry used sheets of different qualities. The most common include IF (inter Interstitial Free) steel and alloyed steel. Use the sheet quality depends on the point of application in the production car. Testing and product testing is a standard part of the process of innovation and production itself. Testing of automotive steels under dynamic conditions is increasingly important. Changing the hardness HV 1 was performed on the fractured bars on the static and dynamic loading conditions. Tests were made on steel IF and S 460.

Effect of Strain History of Steel Sheets on the Mechanical Characteristics of Individual Microstructural Components by Depth Sensing Indentation

“…The content of alloying elements is in a range of 0.01 to 0.1 % and most often is alloyed with manganese. Other alloying elements are Cr, Ni, Mo, W, Ti and another [2].…”
