Shape recovery characteristic of ferrous shape memory alloy by prestrain of biaxial stress

nr katalogowy: 52661

As for the ferrous shape memory alloy, the application to the connection components including the tube fittings [1] and the large- -scale structural material with the functionality is expected. In order to apply this alloy to the connecting materials, it is necessary to estimate the amount of deformation and the connecting strength after prestrain is supplied and shape recovery heat-treatment is performed. Because the forming method of the prestrain is often given not only uniaxially but also multiaxially, the investigation of the shape recovery characteristic to the multiaxial forming is important for wide practical use of the alloy. Authors investigated [4, 8, 9] the shape recovery characteristic concerning the prestrain formed during the uniaxial stretching of tensile test and the biaxial stretching of the hydraulic pressure bulge forming. In addition, the consideration based on the mechanism of the stress-induced martensitic transformation that rules the shape recovery behavior has been studied. However, a wide-ranging investigation has been requested as for the data of the shape recovery strain of the transitional region from the uniaxial stretching to the biaxial stress condition because the shape recovery data are not sufficient. Figure 1 shows the schematic of stress-strain and temperature-strain curve in the shape recovery process. The strain worked by plastic deformation to the specimen in this report is defined as εp of prestrain, and the strain measured by the displacement of the gauge length from before to after the heat treatment is defined as εr of shape recovery strain. When the alloy is applied to a fixed amount of deformation and is heated at a fixed temperature repeatedly, larger shape recovery strain will be developed. This phenomenon is called training effect. It is reported [4] that the shape recovery strains of Fe-28%Mn- 6%Si-5%Cr alloy are measured in the case of without training and with trai[...]
