| Abstract |
In the process of metal foaming, hydride metal often is used as foaming agent. In our experiment TiH_2 was chosen as foaming agent to produce the Al foams. Ti scraps were usually produced in the machining process of panels, wire and pipes. To recycle Ti scraps, Ti scraps of various shape as like plate, chip, pipe etc., were hydrogentreated in self-made hydride furnace. The samples were milled in a ball mill, and then morphologies of milled particles were observed by SEM. Laser and SEM were used to analyze the size distribution, and XRF, XRD, TGDTA analysis were performed to investigate the composition and reaction conditions to prove the foaming possibility of forming agent in the production of Al foams. |
