SBIR-STTR Award

M19 grade silicon steel is the most commonly used soft magnet for a number of applications such as in the manufature of motors. Advanced Materials Corporation proposes to fabricate new, proprietary magnet compositions and bonded magnets employing novel processing techniques. The saturation induction is anticipated to exceed the M19 value by greater than 25%. Magnetic, electrical and mechanical properties will be determined during Phase I.

Benefit:
Successful fabrication of the soft magnets proposed in this effort will enable the design of lighter motors and actuators. This will impact military applications such as in EMALS. Commercial applications include computer disk drives and motors for hybrid electric vehicles.

Advanced Materials Corporation proposes to optimize the process to manufacture soft magnetic materials that are anticipated to be superior to M19 steels both in magnetic induction and in electrical resistivity. Proof-of-concept studies conducted during Phase I have demonstrated the superior magnetic properties of the new material in comparison to M19 steel. Further optimization studies are proposed for Phase II. Magnetic, electrical and mechanical properties will be evaluated. Cost-effective manufacturing process will be investigated during Phase II.

Benefit:
Soft magnetic materials with higher magnetic induction will reduce the weight and volume of the magnetic structures used in the EMALS program. Materials with superior electricl rsistivity will also reduce the eddy current losses. Materials proposed under this Phase II are expected to meet these criteria. Other benefits to the DoD are in the design of light-weight motors and alternators for the
