Newly developed shape memory alloys Ge-Mn-Si, governed by the stress-induced {gamma} {yields} {epsilon} martensitic transformation, are attracting attention due to their low cost and excellent workability. The shape memory effect (SME), although only a one way type, can be nearly perfect for alloys containing suitable amounts of manganese and silicon. However, there are few papers reporting the effect of the melting process, although it is an important factor affecting the material properties. Therefore, in the present study, the authors aim to investigate the casting morphology, shape memory effect, tensile property and fracture behavior for the Fe-30Mn-6Si alloys which are prepared by two melting techniques.
