Abstract:

The character of fracture, phase composition, and structure of a maraging steel of the EI-832 type in large forged pieces (90 mm and more in cross section) have been investigated. Structural factors responsible for the level of impact toughness of the steel subjected to aging in a forged state and after quenching have been revealed. It has been shown that for this steel the manifestation of thermal brittleness that is caused by precipitation of dispersed titanium carbonitrides at grain boundaries and is not eliminated upon subsequent conventional heat treatment is possible.
