High critical current densities up to Jc = 40 000 Acm−2 (77 K, 0 T) were obtained in Bi(2223)/Ag short tape samples, produced by conventional powder in tube technique and cold deformation. Towards the elimination of the final pressing and heating treatments of the tapes and with the expectation of an enhanced matrix stability, first samples with dispersion hardened AgMg sheaths were prepared. Their current carrying capacity and mechanical properties and the microstructure of the Bi(2223) filaments were investigated and compared to the conventional prepared tapes. Without pressing treatments critical currents of 8000 – 10 000 Acm−2 were achieved using AgMg tubes.
