Grain refinement in a Cu–Cr–Zr alloy during multidirectional forging [PDF]

Materials Science and Engineering: A, 2014
Abstract Structural changes during plastic deformation were studied in a Cu–0.3%Cr–0.5%Zr alloy subjected to multidirectional forging up to a total strain of 4 at the temperatures of 300 K and 673 K. The deformation behavior was characterized by a rapid increase in the flow stress at an early deformation followed by a steady-state flow at large ...

Multidirectional Forging Simulation Research on a Tee Joint Valve [PDF]

Advances in Physics Research, 2014
A numerical tee joint valve model was set up in this paper. The numerical forming simulation was implemented. The load of the upper punch was predicted. The final temperature field shows that varying temperatures are within the feasible forging temperature region. The results from the numerical simulation were verified through the practical experiment.
