Evaluation of the Role of Vanadium and Molybdenum in Changing the Kinetics of Austenite Decomposition and the Mechanical Properties of the Simulated Overheating Zone of Low-Carbon Niobium Steels

The effect of vanadium and molybdenum on the kinetics of phase transitions of austenite and the mechanical properties of the overheating zone of low-carbon high-strength steels has been investigated. Changes in the structure and mechanical properties of the alloys upon cooling with rates typical of...

Description
Summary:The effect of vanadium and molybdenum on the kinetics of phase transitions of austenite and the mechanical properties of the overheating zone of low-carbon high-strength steels has been investigated. Changes in the structure and mechanical properties of the alloys upon cooling with rates typical of various welding methods are shown.
