Ising　model　is　a　promising　tool　for　simulation　magnetic　Barkhausen　noise　(MBN)　signal　for　nondestructive　evaluation.　However,　theoretical　modeling　of　two-phase　or　multi-phase　ferromagnetic　materials　are　seldom　reported　by　this　model.　In　order　to　fill　the　blank,　we　extended　Ising　model　combine　with　double　Boltzmann　transition　function　to　simulated　MBN　signal　of　two-phase　ferromagnetic　materials.　The　volume　fraction　was　considered　as　a　vital　parameter　which　effect　the　shape　of　MBN　profiles　directly.　A　continuous　transition　form　was　assumed　and　the　proposed　model　was　simulated　by　Monte　Carlo　algorithm.　The　second　order　Gaussian　curve　was　used　to　fit　the　two-peak　shape　MBN　profile.　This　simulation　show　that　the　first　peak　in　lower　field　increased　and　the　second　peak　in　higher　field　gradually　decreased　with　the　first　phase　simulated　volume　fraction　increases.　In　addition,　the　ratio　feature　about　the　peaks　amplitude　show　a　linear　increased　trend.　The　proposed　model　offer　a　feasible　tool　for　predict　MBN　in　two-phase　materials.　©　2019　The　authors　and　IOS　Press.　All　rights　reserved.
