“…As observed, the enhancement of the intensity ratio, as shown in Figure c,d, is linearly increased while increasing the number of shock pulses, and the obtained results clearly show that the degree of recrystallization increases linearly when increasing the number of shock pulses. The observed results are found to be in good agreement with the attachment energy theory of crystallization − and the previously obtained shock wave-induced results of structural properties. , To draw a parallel line, shocked samples of ammonium dihydrogen phosphate (ADP) and potassium dihydrogen phosphate (KDP) polycrystalline are considered for a better comparative analysis of the observed results. Note that the ADP and KDP crystals have two dominant planes that are (200) and (101), respectively, with the respective growth rates of 2.21 and 2.25.…”

“…Note that the ADP and KDP crystals have two dominant planes that are (200) and (101), respectively, with the respective growth rates of 2.21 and 2.25. In addition, the attachment energies of the (200) and (101) planes for the KDP crystal are 36 and 101 kcal/mol, respectively, and hence, under shocked conditions, the (101) peak intensity increases with respect to the number of shock pulses; similar results have been observed for the ADP crystal under shocked conditions, and the values of the intensity ratio for the (200)/(101) plane are presented in Figure d with respect to the number of shock pulses …”

Here, we present the findings of acoustic shock wave processing inflicted on ammonium sulfate powder samples and demonstrate the unique phenomenon of dynamic recrystallization occurring because of the superheating of the surface within the span of milliseconds. The results of X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) clearly reveal the linear enhancement of the intensity ratio of the planes ( 200)/( 120) and ( 200)/(111) under shocked conditions, and the observed results of dynamic recrystallization are highly relevant to the attachment energy theory of crystallization.
