The aim of this study is to predict ductile to brittle transition temperature of functionally graded steels in both crack divider and crack arrester configurations by ANFIS. FCC 304 stainless steel did not have ductile to brittle transition whereas BCC 1018 steel was determined to have a ductile to brittle transition temperature of about -101 ºC. For some steels the transition temperature can be around 0°C, and in winter the temperature in some parts of the world can be below this. The temperature at which this drop in toughness occurs is called the "Ductile to Brittle Transition Temperature" (DBTT) which is about -75°C for the 0.01% carbon steel above. The aim of this study is to predict ductile to brittle transition temperature of functionally graded steels in both crack divider and crack arrester configurations by ANFIS. since martensitic SS nature has poor impact value as the temperature decrease. those book provide some s-curve graph, but the sudden impact value drop doesnt seem so steep.

This phenomenon was obviously distinct from that in the nanometric cutting of ductile material, where the temperature distribution was uniform. The fracture surface for sets F and G remain largely ductile even at low temperature. The operating temperature of steel is the average temperature during use and can be used to affect the ductility and brittleness of steel.
