英文摘要	The effect of prior particle boundary (PPB) in the FeCrAl alloy prepared by powder metallurgy on the impact toughness is undefined. Mechanism about the effect of PPB on the impact toughness of FeCrAl alloy was investigated by microstructure analysis and in-situ tensile test. The results showed that prior particle boundary precipitations were mainly niobium carbonitrides. During deformation, cracks initiation and propagation in niobium carbonitrides along prior particle boundaries and lead to partial intergranular fracture, low grain-boundary strength and brittle fracture of FeCrAl alloy prepared by powder metallurgy. © 2021, Materials Review Magazine.
