Abstract

A study has been made of the fracture modes associated with toughness minima, observed in notched impact tests at 173K, for a weldable CrMoV steel, quenched from different austenitising temperatures, and tempered in the range 300-900K. The fracture mode at 623K varied from 100% transgranular cleavage for an austenitising temperature of 1523K. The results are discussed in terms of mechanisms for 350 ºC embrittlement, such mechanisms require modification to allow for the difficulty of dissolving alloy carbides at low austenitising temperatures.
