TLDR
In this paper, the authors observed that the amount of iron phase decreased as the IMC thickness grew, and the load bearing capacity of Al/steel interface increased, and that the key point for improving mechanical performance under coach peel loading was to increase the first peak point by reducing Al thinning, increasing the Al nugget size, and limiting the IR layer growth.About:
