| 中文摘要 | microstructures and mechanical properties of the mg-8gd-xzn-0.4zr (x = 0, 1 and 3 wt.%) alloys in the as-cast, as-extruded and extruded-t5 conditions, have been investigated. the peak-aged mg-8gd-1zn-0.4zr alloy during isothermal ageing at 423 k acquires highest mechanical properties, with the highest ultimate tensile strength and yield tensile strength of 314 and 217 mpa, respectively. addition of zn has obvious effect on age hardening responses, especially for 1 wt.% zn addition. it is due to a uniform distribution of beta' phase which can impede the movement of dislocations. however, addition of 3 wt.% zn to the mg-8gd-0.4zr alloy leads to a precipitation of mg3zn3gd2 phase (w-phase). this phase is incoherent with interface of the matrix and becomes cores of the fracture in tensile test at room or elevated temperature. |
