Abstract:
The paper sets out a synergic program by MAG pulsed welding of Duplex stainless steel plates with thickness of 12 mm. The selected filler material was a E2209-16 wire with a diameter of 1.2 mm and as shielding gas Cronigon 2 was used.The root layer was obtained at lower linear energy, of 6.9 kJ/cm, and for the filling layers the heat input was different namely: 10 kJ/cm, 15 kJ/cm and 20.7 kJ/cm.

Abstract:
During heat treatment of carburized steel parts, the transformation of austenite to martensite occurs and a certain amount of retained austenite remains in the hardened layers. The higher content of retained austenite in the carburized layer adversely influences hardness and frictional characteristics and increases susceptibility to fatigue damage. [..]

Abstract:
Shape memory polymers are a special type of polymer, which can recover the permanent shape upon the application of external stimulus. The main advantage of shape memory polymer is the ability of recovering a large amount of strain (usually >400%) in comparison to shape memory alloys (SMP-up to 15%) and shape memory ceramics (2-3%).The material used in this research is Shape Memory Polymer due to its excellent shape recoverability.
