We　report　on　the　development　of　mechanically　strengthened,　highly　textured　Ni-5　at.%　W/Ni-12　at.%　W　composite　materials　prepared　by　a　powder　metallurgical　approach　as　promising　weakly　magnetic　substrates　for　coated　superconductors.　The　key　configuration　of　this　composite　substrate　consists　of　a　thin,　sharp　cubic　textured　Ni-5　at.%　W　layer　on　a　Ni-12　at.%　W　alloy　core,　thus　providing　a　mechanical　reinforcement　while　decreasing　the　saturation　magnetization　of　the　whole　substrate.　The　composite　substrates　have　a　sharp　cubic　texture　at　the　top　Ni-5　at.%　W　outer　layer　and　their　yield　strength　reaches　272　MPa,　exceeding　that　of　the　commercially　used　Ni5W　substrates　by　a　factor　of　1.6.　The　saturation　magnetization　of　the　composite　substrate　Ni5W/Ni12W/Ni5W　is　substantially　reduced　when　compared　to　that　of　pure　Ni　and　Ni-5　at.%　W　substrates,　respectively.
