Abstract:

In this paper a review of current topics of interest with respect to the interrelationship between microstructure and toughness is given. In the analytic treatments important parameters are particle size and spacing, the modulus, strength level and a measure of dutility. Metallurgical variables include mode of failure cleavage, intergranular, transgranular, grain size, twins, temper embrittlement, slip mode, and sulfide morphology. Examples of the influence of these various factors on fracture toughness are given.
