Abstract


This article through adjustment 2024Al and 6061Al alloy Cu elements and the Mg element content , the use of the pressure infiltration prepared nine different matrix content of alloying elements submicron the Al 2 < / sub > O 3p < / sub > / Al - Cu - Mg system and the Al 2 < / sub > O 3p / Al - Mg - Si composite material . Brinell hardness ( HBS ) , the real-time detection of thermal cycles , transmission electron microscopy ( TEM ) , room temperature tensile properties of test analysis and testing means more systematic study of different content of alloying elements 30vol%-0.15μm-Al 2 < / sub > O 3p / Al composites aging microstructure and the micro deformation resistance and dynamic dimensional stability , and to explore the influence mechanism of alloying elements on the dimensional stability of composite materials . For a O the Al 2 < / sub > 3p < / sub > / Al - Cu -Mg based composite material , with the increase of the content of elements of Cu , the composite material by a single S ' phase precipitates gradually transformed into S 'phase ?? phase co - precipitation of micro- yield strength increases gradually . Al 2 O 3p / Al-6.5Cu-Mg composite dislocations and precipitates scarce, dimensional stability under no-load conditions . Mg element is too high or too low on the aging inhibition of Mg element content in the the 1.2 2 < / sup > .0 range Al 2 < / sub > O 3p / Al- Cu - Mg composite material having a high tensile strength and micro - yield strength . Under no-load conditions , Mg element content below 1.2 or above 2.5 will improve the dynamic dimensional stability , reduced ? Values ??. The dimensional stability of the composite after thermal cycling process have greatly improved. Summarizes the experimental law of composite aging precipitation and found that sub-micron Al 2 < / sub > O 3p / Al - Cu - Mg composite matrix alloy Cu / Mg atomic ratio at 1.8 2 the .3 range of 4.3 or more , to reflect the excellent dimensional stability performance . Al 2 < / sub > O 3p / Al - Mg - Si composite materials, 6061Al matrix showing the precipitated phase and dislocation scarce under no-load conditions ? Value also the smallest . Treatment of T6 TCC process , the dimensional stability is greatly improved .
