摘要： PROBLEM TO BE SOLVED: To provide a method of making nano-/submicron-sized grains in a material to be worked having side faces.
SOLUTION: A die (30) has an entrance channel (38) having a longitudinal axis line and an exit channel (40), and the entrance channel (38) and the exit channel (40) have an approximately rectangular shape and communicate with a die cavity (36). This method has a step where a first sacrificial material having a complementary dimension to the material to be work is prepared, a step where the first sacrificial material and the material to be worked are placed on the entrance channel (38) by aligning with the longitudinal axial line and a step where the combined body of the first sacrificial material and the material to be worked is extruded through the intersection part of the entrance channel (38) and the exit channel (40). By shear deformation generated, the nano-/submicron-sized grains are formed in the material to be worked. This composition lowers frictional action and a homogeneous nano grain structure is produced thereby.
