High strength magnetic material

Sintered samples of Sm2Fe17Xy with sufficient mechanical strength for use as the permanent magnetic materials are obtained by high-pressure... 

High-purity metals and superalloys are required for the aeronautics, electronics, instruments, space, and defense industries the raw materials are at present imported. Primarily, these special metals include nickel-and cobalt-based superalloys, high-strength iron-based alloys, titanium-based alloys, controlled-expansion alloys, and magnetic materials. Keeping in view the importance of these metals and alloys and the expertise available in India for making them, the NCST has identified two projects for their development the setting up of a special metal and superalloys plant and the development of controlled-expansion alloys. 

NMR spectroscopy plays an important, complementary role, since it uses biopolymers in solution. High-field magnetic instruments have extended the upper size limit to medium-size systems. NMR spectroscopy requires fairly high concentrations so that solubility of the material is a crucial question. NMR has its particular strength in detecting association phenomena using N15- and/or CIS-labeled material [5]. 

Titanium-aluminum-niobium alloys have been developed for biocompatible, high-strength surgical implants (Semlitsch et al. 1985), while metal-resin composites containing niobium as filler have potential use as restorative materials in dentistry (Misra and Bowen 1977). The metal possesses superior superconductive properties in strong magnetic fields, which may be...
