Multi-material can have functional properties, which are not typical for the materials of they composed (for instance, shape-changing effect). This be used in robotics, micromachines, aerospace, and other fields. In this work, 316L/FeNi36 multi-material produced by selective laser melting was investigated. The results show that interfacial zone exhibits mixing regions two alloys but no defects. microstructure is constituted large grains with epitaxial growth, propagate a directional manner from 316L alloy through to FeNi36 region. sample displays three different zones chemical composition: composition zone; zone. size approximately 50 µm. presence distinct phases: γ-Fe; γ-Fe64Ni36; α-Fe. hardness 163 HV, followed an 200 HV then, 214 HV. Functional tests demonstrate effect directly correlated variation thermal expansion coefficient temperature. For achieving most pronounced effect, temperature range 25-215 °C more suitable.
