DESCRIPTION:Dr. Norbert Babcsan\nBay Zoltán Foundation for Applied Resear
 ch\, Miskolc\, Hungary\nAluminium foams are the frontiers of new light wei
 ght materials. They are created by gas injection foaming\, that is by inje
 cting gas bubbles into the metal melt through an orifice. We developed an 
 original metal foaming technology which resulted in a new type of metal fo
 am called ALUHAB\, which can be produced with controlled bubble size and m
 echanical properties. It is manufactured from a special foamable aluminium
  alloy containing ultrafine particles (80-3000 nm sized). The technique re
 lies on a direct gas injection with a loud-nozzle\, and the bubbles are re
 gulated by the frequency and power of the sound (so called acoustic radiat
 ion pressure). The size of the bubbles is depending on the applied sound p
 ressure. The oscillation induced external force (acoustic radiation force)
  modifies bubble formation mechanism and helps bubble detachment in its ea
 rly stage. This extra force can significantly decrease the bubble size int
 o the sub-millimetre range and it can be kept uniform. This technology pro
 vides extremely stable re-meltable metal foams\, which can be casted into 
 complex shape while the material properties do not change. The ALUHAB once
  made can be transported and re-melt at the place of the use (for example 
 at a foundry).
