dc.description.abstract | Despite the recognition of thermal shock and thermal fatigue as common failure modes in cemented carbide applications, the information on the influence of the microstructure on the resistance of hardmetals to abrupt temperature changes is rather scarce. In this paper, the strength behaviour of cemented carbides after severe thermal shock damage is investigated. In doing so, cemented carbides were subjected to thermal shock at two temperature ranges (¿T of 400ºC and 550ºC) and their retained strength evaluated as a measure of their thermal shock resistance. Residual strength results are then related to crack initiation (R) and propagation (R’’’’) Hasselman parameters. Results indicate that the finer the microstructure, the better the resistance to the nucleation of thermal shock damage of hardmetals. This strength trend is in accordance with higher R and lower R’’’’ parameters for the studied materials. |
