Nano-indentation test was carried out on the coating surface after specimens were drawn over different die radii. The indentation hardness results (measured in GPa) of Material #1 obtained before and after forming are shown in Fig. 11. It is observed that the nano-indentation results can vary significantly due to probenplacement. This is especially true for the coating with color pigment as the probe could come in contact with pigment particles and produce high hardness readings. Excluding the outliers (hardness reading above 0.3 GPa), it is observed that the coating exhibits strain softening behavior. The averaged indentation hardness decreases with decreased die radius (hardness of 0.200, 0.216, 0.190, and 0.157 GPa for no deformation, 10T, 5T, and 1T specimens, respectively). This implies that the scratch resistance of the formed prepaint products is reduced and can be different due to different degree of strain softening..
