M. Mihaliková, A. Lišková, Faculty of Metallurgy, Technical University of Košice, Slovakia The aim of this experimental research was to perform an analysis of deformation characteristics on two different types of steel: IF steel, and micro-alloyed steel were used automotive industry. For that purpose changes of properties of these materials were carried out by static 10-3 · s-1 and dynamic 103 ...

concentric bracing is one of the most common lateral load resistant systems in building frames, and areapplied to many structures due to their manufacturing simplicity and economics. an important deficiency in thebracing members is their irregular hysteretic loops under cyclic loading. in order to overcome this problem, it isadvised to restrain braces against buckling under compression, since b...

recently, bulk nano-structured materials produced by severe plastic deformation (spd) have attracted scientists attention.  materials produced by spd are of great importance because of (1) non-porous structure, (2) great mechanical properties such as high strength and toughness and (3) proper dimension for mechanical and physical testing.  several methods have been introduced for imposing the s...

The Interstitial Free (IF) grade steel sheets are used for auto body applications where these sheets require good formability/drawability property. To achieve this property the cold rolled sheets are annealed to obtain desirable texture in the recrystallised grains to avoid material failure during forming operation. The paper deals with an ultrasonic technique to determine the condition of the ...

In this research work, investigations are carried out on Continuous Wave (CW) Nd:YAG laser welding system after preliminary experimentation to understand the influencing parameters associated with laser welding of AISI 304. The experimental procedure involves a series of laser welding trials on AISI 304 stainless steel sheets with various combinations of process parameters like beam power, beam...
