A novel small‐angle X‐ray scattering modelling approach is introduced for the analysis of precipitation behaviour in metallic systems exhibiting scattering signals with streaks originating from the embedding matrix. This approach enables in situ tracking of the microstructural evolution, such as the volume fraction and size of second phases, during ...

Estimation of the engineering elastic constants of a directionally solidified superalloy for finite element structural analysis [PDF]
The temperature-dependent engineering elastic constants of a directionally solidified nickel-base superalloy were estimated from the single-crystal elastic constants of nickel and MAR-MOO2 superalloy by using Wells' method.

Hot Tearing in Directionally Solidified Ni-Base Superalloys
The hot tearing mechanism has been studied in directionally solidified (DS) Ni-based superalloys with columnar grain structures. Castability tests and optical metallography of quenched samples were employed to explore the effect of microstructural evolution, grain boundary characteristics on the susceptibility of hot cracking formation during DS ...
