Influence of Ni/Mn concentration ratio on microstructure and martensitic transformation in melt spun Ni–Mn–Sn Heusler alloy ribbons

•Heterogeneous microstructure was obtained in Ni–Mn–Sn Heusler melt spun ribbons.•Increase of Ni/Mn ratio changes a structure from one into two phase.•Modulated martensites were formed in ribbons with highest Ni/Mn ratio.•Grain boundaries of austenite were preferential for nucleation of martensite.•...
