Based composites become first choice.The aluminum matrix composite of carbon nanotube enhancing has both intensity, weight and cost advantage, is applicable in very much
In manufacture rotating ring forge piece blank reheating, but the problem that generally existing upper intensity limit is limited.Traditional method for preparing aluminum-based composite material such as heat
Dispersant etc. to be added when the technologies such as isostatic sintering are due to batch mixing, there are more microscopic void, interfaces to tie for the material of acquisition
The defects of bad is closed, subsequent forging requirement is cannot be satisfied；Aluminium base prepared by casting answer material, and there is also more blow holes, inclined
The defects of analysis, is also not used to forging blank, can not meet requirement.
