Summary on Grant Application Form
The thermomechanical processing of microalloyed steel has been employed for some time in the production of plate and sheet material in order to optimise properties such as strength and impact toughness. This technology was subsequently applied to the bar and forging industry with considerable success, considering the more complicated geometry, thicker sections and localised states of strain. The central feature of thermomechanically processed steel austenite is the ultra-fine grain size in the final transformation product. This fine grain size is known to cause both high strength and high resistance to brittle fracture by cleavage. While achieving high strength in structural steel is rather straight forward and well-understood, achieving a fine and uniform, grain size is a more complex task related to the synergy which exists between the composition of the steel and its processing. It is the aim of this research programme is to quantify the significance of those hot deformation processing parameters during conventional controlled rolling(CCR) which are conducive to achieving both a fine and uniform austenite grain size.
