Equal Channel Angular Pressing (ECAP) of hollow profiles made of titanium
IOP Conference Series: Materials Science and Engineering, 2017 Cylindrical tubes made of commercially-pure titanium (CP-Ti) filled with various mandrels (metallic as well as non-metallic materials) were processed by Equal Channel Angular Pressing (ECAP). Different temperatures (500°C down to room temperature), routes (Bc, B<sub>120</sub>, C), tools and number of passes (1-6) were ...

Scaling up of Equal Channel Angular Pressing (ECAP) for the Production of Forging Stock
Materials Science Forum, 2006 Over the past two decades equal channel angular processing (ECAP) and other severe plastic deformation (SPD) processes have been shown, in the laboratory scale, to produce material with promising properties for industrial applications. In particular, ultrafine grain (UFG) metals produced by ECAP process, for example, have been shown to exhibit higher ...
