Effect of equal-channel angular pressing on the creep resistance of precipitation-strengthened alloys

, 2010
Despite intensive research efforts in precipitation-strengthened alloys processed by equal-channel angular pressing (ECAP), so far only a few investigations have been conducted on their creep behaviour and the results from these studies are controversial.

FINITE ELEMENT ANALYSIS OF ROTARY-DIE EQUAL CHANNEL ANGULAR PRESSING

, 2019
In this paper, the finite element method (FEM.) was applied to analyze the plastic flow and strain hardening behavior of pure copper, subjected to rotary-die equal channel angular pressing (RD-ECAP) up to four passes. The die was rotated 90' counter
