Failure analysis of a crusher jaw - ScienceDirect

Jan 01,  · The study revealed that the failure of locally produced crusher jaws was not due to wrong chemical composition but to the precipitation of carbides at grain boundaries and in grains. This led to the formation of microcracks and their propagation under impact action of crushing, which effectually led to early brittle fracture failure.
