Aluminum alloy
Spinning Water Atomization Process (SWAP)
Hot extrusion
抄録
The characteristics of hot extruded aluminum alloy when using the rapidly solidified powder Spinning Water Atomization Process (SWAP) have been investigated. SWAP is one of advanced powder processing technologies to prepare high-performance powder particles with fine microstructures. In this study, A7075 aluminum alloy powder were produced by SWAP, and no intermetallic compound was detected in the raw powder. Microstructures and micro-hardness dependence on annealing temperature has been examined. Mechanical properties of the powder metallurgy (P/M) aluminum alloys consolidated by hot extrusion were superior to those of wrought alloys using ingot billets. A7075 wrought P/M alloys via T5 heat treatment show yield stress of 370 MPa and elongation of 15 % at the extrusion temperature of 623 K.

SWAP is one of advanced powder processing technologies to prepare high-performance powder particles with fine microstructures. In this study, A7075 aluminum alloy powder were produced by SWAP, and no intermetallic compound was detected in the raw powder. Microstructures and micro-hardness dependence on annealing temperature has been examined. Mechanical properties of the powder metallurgy (P/M) aluminum alloys consolidated by hot extrusion were superior to those of wrought alloys using ingot billets. A7075 wrought P/M alloys via T5 heat treatment show yield stress of 370 MPa and elongation of 15 % at the extrusion temperature of 623 K.
