... Abstract This article describes the mechanics and processing characteristics of equal-channel angular extrusion (ECAE). Tool design considerations for the ECAE are discussed. During ECAE, severe plastic strains and simple shear deformation mode contribute to strong, sometimes unusual effects of...

Angular particles indent the wear surface to a greater extent than rounded particles, leading to higher wear rates. In addition, angular particles are more efficient in cutting and machining ( Ref 11...

... , then the normal strain calculated from Eq 3 would have a negative sign, indicating that the strain was compressive. Deformation of a body can result not only in the change of length of a line in the body, but it may also produce a change in the angle between two lines. The resulting angular change...
