Abstract: The effect of aging temperature and time on the damping property of ZMnD-1J Mn-Cu alloy was studied. Furthermore, the changes of crystal structure in the process of aging were investigated by XRD. The results show that, the damping property of ZMnD-1J Mn-Cu alloy is highly sensitive to the aging temperature and time .When the temperature is controlled in a narrow range, about 430℃, the time is about 2h , the best damping property is obtained. There are close relationships between the damping property and crystal structure. Only fcc structure appears high damping property. The abrupt change of crystal structure leads to the sudden change of damping property after aging.
Crystal structure changes of Mn-Cu damping alloy at aging
Abstract:
The effect of aging temperature and ti me on the damping property of ZMnD-1J Mn-Cu alloy was studied. Furthermore, th e changes of crystal structure in the process of aging were investigated by XRD. The results show that, the damping property of ZMnD-1J Mn-Cu alloy is highly sensitive to the aging temperature and time .When the temperature is controlled in a narrow range, about 430 ℃, the time is about 2 h , the best damping prop erty is obtained. There are close relationships between the damping property and crystal structure. Only fcc structure appears high damping property. The abrupt change of crystal structure leads to the sudden change of damping property afte r aging.
