INTRODUCTION, MAJOR ACCIDENTS HAPPENED IN INDIAN NAVY, DBTT AND METALLOGRAGHYAbstract
The Ductile-to-Brittle Transition Temperature (DBTT) is a phenomenon that is widely observed in metals. Below critical temperature (DBTT), the material suddenly loss ductility and becomes brittle. The controlling mechanism of this transition still remains unclear despite of large efforts made in experimental and theoretical investigation. All ferrous materials (except the austenitic grades) exhibit a transition from ductile to brittle when tested above and below a certain temperature, called as Transition Temperature. The paper deals with the determination of the ‘Ductile to Brittle Transition Temperature of stainless steel. Work carried out in this is purchasing the material followed by test specimen preparation.
