Abstract: A method of manufacturing a stable multifilament multiconductor with reduced losses includes making a billet by the single stacking technique. Conductive matrix rods and/or resistive matrix rods are disposed in the superconductor filament of the billet to form matrix channels between bundles of superconductor filaments. The rods preferably have a polygonal section, preferably square or rectangular, more preferably hexagonal.

Abstract: A method of manufacturing a blade made of .alpha..beta. titanium including an insert of metastable .beta. titanium,according to the invention:a blade body made of .alpha..beta. titanium is made to the finished design dimensions, said blade body made of .alpha..beta. titanium including a location designed to receive said insert made of .beta. titanium:said insert made of .beta. titanium is put into solution; thenhardening treatment is performed to harden said insert made of .beta. titanium; thensaid insert made of .beta. titanium is welded to said location of said blade body made of .alpha..beta. titanium to the finished design dimensions using a welding technique having localized and controlled energy density.
