Stabilisation of aluminium foams and films by the joint action of dispersed particles and oxide films

X-ray radioscopies of AlSi9Mg0.6/SiC/10p foam blown with (a) air and (b) Ar as an injection gas. Both foams were surrounded by air. (c) Ar was used as injection gas and foam was surrounded by Ar atmosphere. The images were taken after stopping bubbling and holding at 680 °C for 600 s.206
