Recrystallization　in　multi-phase　materials　containing　particles　with　a　two-class　size　distribution　was　studied　with　modeling　and　experiments.　A　3D　Monte-Carlo　model　combined　with　deterministic　criteria　was　developed　to　describe　nucleation　stimulated　by　coarse　particles　and　pinning　effect　of　fine　particles.　The　influences　of　various　particle　parameters　on　nucleation　and　growth　of　recrystallizing　grains　were　quantitatively　studied　by　simulations.　The　results　show　that　the　efficiency　of　particle　stimulated　nucleation　depends　on　the　stored　energy　in　the　particle-affected　region　and　the　local　distribution　of　fine　particles.　The　competition　between　the　local　stored　energy,　as　the　driving　force　for　recrystallization,　and　the　dragging　force　from　fine　particles,　determines　the　final　state　of　complete　recrystallization,　partial　recrystallization　or　fully　inhibited　recrystallization　in　the　whole　material.　Good　agreements　of　morphologies　and　recrystallization　kinetics,　are　found　in　comparison　between　experiments　and　simulations　for　a　series　of　Al-(0.3-1.1)%Zr　(mass　fraction)　alloys　under　the　same　deformation　and　particle　parameters.
