In this paper, we introduce a novel intellectual damping materialshape memory alloy metal rubber (SMAMR), which is made from the shape memory alloy through the process similar to that for metal rubber. The shape craft, shape memory effect and mechanical properties are tested and discussed. The results show that the SMAMR has the combination properties of both shape memory alloy and metal rubber, such as high elasticity and damping capacity, low density, designable porosity, shape memory effect, and temperature dependent mechanical properties. The SMAMR not only has modulus and loss factor varying linearly with temperature during the phase transformation between Martensite and Austenite, which is quite available in the active control of vibration; but also has the modulus and loss factor large enough to be used as bearing structure. So the SMAMR is a significant integration of both functional material and structural material, and is quite attractive in active vibration control.
