The invention provides a W-V alloy functionally-graded material and a discharge plasma sintering method thereof. The W-V alloy functionally-graded material is moulded through sintering a W layer and a V layer which are located at the two sides, and a plurality of W-V alloy layers which are located between the W layer and the V layer, wherein the contents of W components in the W-V alloy layers are lowered at a constant gradient from the W layer to the V layer, and the contents of V components are increased at a constant gradient from the W layer to the V layer. According to the W-V alloy functionally-graded material and the discharge plasma sintering method thereof, which are provided by the invention, the W layer is independently separated and sintered, and then transition is made to the gradient layers of the V layer from the W layer for sintering through a fractional sintering process, thus the compactness degrees from the W layer to the layers of the V layer in the prepared W-V alloy functionally-graded m
