报告摘要：

In this presentation, the capability of the integrated CALPHAD and phase field modeling with critical experiments in the design and control of novel microstructure in metals and alloys, will be demonstrated through its application in

1) Enabling large superalloy parts using compact co-precipitation of  and  in IN718 alloys;

 

2) Design and formation mechanism of self-organized core/shell and core/shell/corona structure composite powder in immiscible liquid system;

3) Exploring a newly discovered, non-conventional, solid-solid phase transformation pathway based on the so-called pseudo-spinodal mechanism that offers a new design strategy for titanium-alloys (Ti-alloys) with extremely fine and uniform microstructures that could potentially have highly attractive balances of mechanical properties;

4) Exploring the physical origins leading to the variant selection (preferential selection of a subset of all twelve orientation variants) that occurs frequently during the  transformation in response to microstructural, temperature and stress fields, spanning several length scales, ranging from subgrains to the polycrystalline

aggregate, experienced during heat treatment alone and thermal me chanical processing of Ti-alloys
