The valuable contribution of stress to the thermal stability of nanograined polycrystalline alloys

E-Mail
Nanograined metals and alloys, whose grain size is less than 100 nm, exhibit extremely high strength and high ductility, possessing excellent mechanical properties. Nanograined materials, however, have a large number of grain boundaries and hence high total grain boundary energy. At a temperature higher than a critical temperature, grains in nanograined materials will grow spontaneously to reduce the grain boundary energy, leading to thermal instability of the materials. A common approach to enhance the thermal stability is via grain boundary energy segregation, which thermodynamically lowers the grain boundary energy and kinetically pins the movement of grain boundaries, thereby enhancing the critical temperature of recrystallization. However, the role of mechanical stresses in the thermal stability has not been systematically studied yet. ....
