Precipitation at Tungsten/Tungsten Interfaces in Tungsten–Nickel–Iron Heavy Alloys [PDF]
Powder Metallurgy, 1986 AbstractA study of precipitation at the tungsten grain boundaries in the tungsten–nickel–iron ternary alloy system has been undertaken. Scanning and transmission electron microscopy techniques have been used to study the effect of various post-sintering heat treatments on the precipitation reaction.

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.
