| Abstract | Hot compression cracking of as-cast Inconel 625 alloy is investigated utilizing high temperature and high strain rate compression tests. The formation mechanism of the hot crack is systematically investigated based on grain growth and crystal slipping. Scanning electron microscopy (SEM) and electron backscattered diffraction (EBSD) analysis are used to characterize the crack morphology and microstructure. SEM results showed that the hot cracking during hot compression of Inconel 625 alloy is determined to be quasi-cleavage fracture. The formation of carbide (NbC) plays a key role in the formation and propagation of the hot crack. The various slip systems activation strongly contributes to the overall growth of the dynamic recrystallization (DRX) grains. In addition, subgranular boundary formation within the grown grains is attribution to various slip systems activation in different local regions. The initiation and propagation of the hot compression cracks in Inconel 625 alloy depend on the development of the subgranular boundary within the grown grain. |
