The microstructure of WC-10Co cemented carbides with different addition amount of plate-like WC seeds is shown in Fig.2. The addition of plate-like seeds helps the development of plate-like WC grains. With the increase of seed addition, more plate-like WC grains with more regular shape and bigger aspect ratio are formed, and the average size of WC grains becomes larger. When 10 mass% seeds are added, the amount of plate-like WC grains and the average grain size reach the maximum values, but there are some pores.
