Grain Boundary Evolution for the 5 Cases due to Heating Impulse Shown in Fig. 5. (a–c) Show the grain structure evolution with no particles present (Case 1) at \(t=0.151\,s\), \(t=0.301\,s\) and \(t=0.451\,s\) respectiveley. (d) Shows the final grain structure at \(t=0.451\,s\) for the case where 320 particles, each with \({r}_{p}=4\,\mu m\), and \({k}_{particles}={k}_{grains}\) (Case 2). (e) Shows the final grain structure at \(t=0.451\,s\) for the case where 320 particles, each with \({r}_{p}=4\,\mu m\), and \({k}_{particles}\ne {k}_{grains}\) (Case 3). (f) Shows the final grain structure at \(t=0.451\,s\) for the case where 20 particles, each with \({r}_{p}=16\,\mu m\), and \({k}_{particles}={k}_{grains}\) (Case 4). (g) Shows the final grain structure at \(t=0.451\,s\) for the case where 20 particles, each with \({r}_{p}=16\,\mu m\), and \({k}_{particles}\ne {k}_{grains}\) (Case 5). Second phase particles are shown in magenta.
