(2) The characteristicmicrostructure of the in situAl2Si4O10/Al composites via SLM tended to
transfer fromthe irregularnetworkstructure toanearlysphere-likenetworkstructure inregular
formingbyincreasingthe laserpower.
(3) Asahighlaserpowerwasemployed,ahighpeaktemperaturewasacquiredcorrespondingly,
andtheresultant Marangoni convection was generated with a high velocity, favoring the
sufficientdispersionof thereinforcementswithin themoltenpool.
(4) Theformationmechanismof insituAl2Si4O10 andthedistributionevolutionof thereinforcement
particles during the SLM processing of Al2O3/AlSi10Mg mixed powder were present.
Formationof the insituAl2Si4O10phasecouldbeattributedto thereactionamongdissociative
[Al], [O], and [Si] atoms, and thedistributionof reinforcementparticleswas speculated tobe
influencedsignificantlybyMarangoniconvectionandtheviscosityof themoltenmaterial.
