It is shown that simple shear can be considered a ''near ideal'' defor
mation method for structure and texture formation in metal-working. Eq
ual channel angular extrusion (ECAE) is a special industrial process e
mployed to realize this method. In comparison with traditional metal-w
orking operations, this process has a number of advantages; the most i
mportant is that extra-large, strictly uniform and unidirectional defo
rmations can be produced under relatively low pressure and load for ma
ssive products. The unusual effects that are observed in both the stru
cture and physical-mechanical properties of various metals and alloys
suggest many new applications of the simple shear method in materials
synthesis and processing.
