A PROCESS OF FRAGMENTING A SUBSTRATE OF ALUMINIUM OR AN ALLOY THEREOF |
| 摘要 |
<p>This invention relates to (a) a powder of aluminium or an alloy thereof having at least 0.04% w/w of gallium concentrated on the grain boundaries of the particles in the powder, (b) a method of producing the powder by fragmenting a substrate of aluminium or an alloy thereof coated with gallium under a deforming stress, and (c) a method of forging the powder. The powder can be forged into complex shapes using fewer steps than hitherto possible especially with aluminium powders.</p> |
