Microstructural and mechanical characterization of welded joints on innovative high-strength steels

INTRODUCTION In recent years car-bodies are more and more frequently constructed with innovative high-strength steels, both to reduce the vehicles weight and to improve the passenger safety. The main requirements for these steels in service are high fracture strength and good energy absorption, in relation to the possibility of the automobile accidents, and good fatigue resistance, relatively to the normal use of vehicle
