Synergism between coherent precipitation strengthening and FCC-HCP type transformation-induced plasticity

Materials & Design, 2022
It is becoming a trend that many strengthening methods are applied at the same time to overcome the strength-ductility trade-off. However, the combination of precipitation strengthening and transformation-induced plasticity (TRIP) is rarely used ...

TEM Study of High-Temperature Precipitation of Delta Phase in Inconel 718 Alloy [PDF]

, 2011
Inconel 718 is widely used because of its ability to retain strength at up to 650◦C for long periods of time through coherent metastable γ” Ni3Nb precipitation associated with a smaller volume fraction of γ’ Ni3Al precipitates.

A case study of HF radar spectral width in the post midnight magnetic local time sector and its relationship to the polar cap boundary [PDF]

, 2002
International audienceThe aim of this paper is to advance the current understanding of the spectral width parameter observed by coherent high frequency (HF) radars. In particular, we address the relationship of a frequently observed gradient, between low
