Abstract Scope |
The stress states surrounding twin-boundary interactions have been widely studied in Mg and other hcp metals, but primarily for single phase alloys. In reality, many commercial Mg alloys contain a substantial volume fraction of hard micron-sized intermetallic particles, primarily located at grain boundaries. These hard particles alter the local stress state, but the role in twinning behavior had not been systematically explored. In this work, we use an elastoplastic fast fourier transform polycrystal plasticity code to systematically interrogate the role that grain boundary particles play in twin propagation, thickening, and transmission across the boundary. The implications for microstructural engineering for enhanced mechanical performance will be discussed. |
