| 20110262766 | Method of Producing a Metal Foam by Oscillations and Thus Obtained Metal Foam Product - The invention relates to a method of producing a bubbled metal foam, wherein adjusting the size of the bubbles takes place simultaneously with forming the bubbles by means of oscillations induced by longitudinal waves within the formation region of the bubbles. In this way, a decrease in bubble size which can be effected in an uncontrolled way after said bubbles had been created can be avoided. | 10-27-2011 |
