| Abstract: | The recrystallization behavior of Mo wires doped with various contents of La2O3,which were prepared by powder metallurgy method,was investigated using TEM and SEM in detail.It is shown that the recrystallization temperature and recrystallized microstructure of Mo-La2O3 wires are strongly dependent on the La2O3 contents.An interlocked large grain structure is formed in Mo-La2O3 wires with contents of 0.2-0.4 wt% La2O3,on the other hand,Mo─La2O3 wires containing less than 0.1 or more than 0.8 wt% La2O3 show equiaxed grain structure.The reason for this is the difference between the longitudinal interparticle spacing and the transverse spacing of La2O3 particles in various Mo-La2O3 wires,which was observed by using TEM. |
