STUDY ON FAST FORGING PROCESS CHARACTERAISTICS OF 20MN FORGING PRESS
Proceedings of the JFPS International Symposium on Fluid Power, 2008 The E/H servo cartridge valve is adopted to control the system of 20MN Forging Hydraulic Press. Its characteristics ,such as short response time, high control accuracy and so on, are extremely fit for forging hydraulic press. As a result the high forging times and accuracy can be achieved.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
