摘要：

Tungsten single crystals grown by the secondary recrystallization method from hot-rolled tungsten plates doped with CaO and/or MgO have been characterized by the Berg-Barrett method and the X-ray double crystal method. The perfection of the crystals was found to be better than that of a tungsten single crystal grown by the conventional electron beam zone melting method.
