Preparing method and processing of Tb-Dy-Fe alloy samples with [(1) over bar 10] axial orientation as well as their magnetostrictive properties have been studied. It has been found that the magnetostrictive strains of polycrystal samples with [(1) over bar 10] axial orientation can reach (1550 similar to 1900) x 10(-6) in a low magnetic field less than 80 kA/m, which are equal to or somewhat better than that of the polycrystal samples with [11 (2) over bar] axial orientation.

In this paper, technology margin experiment of hollow cathode fusion are welding (FAW) and penetrating are welding (PAW) is presented in detail. The advantages of PAW, compared with FAW, are better weld formation, narrower welds, as well as a larger welding technology margin. Technological experiment and hydraulic test for the Ti alloy pressure vessels with PAW are described. Also, the weld formation control on Ti alloys is preliminarily analyzed. Finally, conclusions are addressed.
