 sium alloys - Dr Dikai Guan\, University of Southampton

DESCRIPTION:Magnesium alloys\, known for their low density and high streng
 th-to-weight ratio\, are increasingly important in the aerospace and autom
 otive industries. Understanding the static recrystallisation (SRX) and gra
 in growth behaviour of these alloys is crucial for optimising their mechan
 ical properties and manufacturability. This seminar will explore the funda
 mental mechanisms of SRX in magnesium alloys via using quasi-in-situ elect
 ron backscattered diffraction (EBSD) and lab-based diffraction contrast to
 mography (LabDCT) focusing on the microstructural evolution during anneali
 ng. We will discuss the influence of nucleation site\, alloying elements\,
  initial grain size\, and deformation conditions on the kinetics of recrys
 tallisation. \nRecent advancements in EBSD and LabDCT techniques have sign
 ificantly enhanced our ability to collect large datasets with high acquisi
 tion speeds\, enabling the scanning of large areas. However\, post-data pr
 ocessing remains challenging and time-consuming when extracting quantitati
 ve and statistical results simultaneously. This seminar will also introduc
 e our newly developed Track-Rex toolbox (https://github.com/TrackRex/Track
 -Rex)\, which allows the automatic tracking of thousands of grains and sum
 marising the customised results within a few hours. These findings and new
  insights will offer a comprehensive overview of the evolution of recrysta
 llisation grains throughout the entire SRX and grain growth process and he
 lp us tailor the microstructure.\n
