Accelerated Carbide Spheroidisation and Grain Refinement (ASR) in RSt37-2 Steel
Original language description
One of current efforts aimed at ordinary structural steels is to achieve high strength combined with sufficient ductility with minimum production cost. These properties should result from a new thermomechanical treatment process leading to ferrite grainrefinement, carbide spheroidisation and changes in the carbide distribution in the microstructure. This newly-developed ASR process (Accelerated Spheroidisation and Refinement) has the following stages: heating a steel workpiece through thickness to no higher than the Ac1 transformation temperature and subsequent mechanical working. The mechanical energy introduced by forming leads to rapid heating of the entire workpiece above Ac1. The workpiece is then air-cooled in a conventional fashion. The combination of a suitable pre-heating temperature and an appropriate amount of strain lead to transformation of initial ferrite-pearlite microstructure with lamellar pearlite into a desired ferrite matrix with spheroidised carbides throughout th
