Superconducting Properties of the Dilute Magnetic Alloys Pb-Mn, Sn-Mn and Hg-Mn Obtained by Ion Impl1] (1964). Many fascinating results have been predicted (for a review see ), especially for superconducting alloys , but there has been a lack of techniques for preparing interesting alloys which often have a very low solubility limit (as many 3d-elements in non-transition metals).

Ion Implantation and Backscattering from Oxidized Single-Crystal Copperining varying amounts of aluminum are quite common, and are denominated aluminum bronzes. These alloys have improved characteristics like corrosion resistance, high strength, hardness and wear resistance. Alloys containing up to 18.4% aluminum have been studied as well as their different metallurgical phases, and their resistance to corrosion (1).

Encyclopedic Dictionary of Polymersund Nb.Sn and the interstitial compounds NbC and NbN with NaCl structure. Both chemically active and inert ions were used in order to distinguish between radiation damage and other effects influencing the superconducting transition temperature T.. Successively larger decreases in T., due to radiatio
