The usage of different TiH2, particle sizes is an approach to adapt the onset of gas evolution temperature of gas blowing agent and improvement of the macrostructure of foamed aluminum. The higher foam expansion and coarser gas bubbles foam structure are corresponding to the coarser particle sizes TiH2 while the finer macrostructure and lower mean material thickness and quite lower maximum expansion fate the finer grade of TiH2.
