Latest Patents
Hashimoto's latest patents include innovative methods for preparing permanent magnets. One of his notable inventions involves a permanent magnet that contains R, T, and B as main ingredients, where R is either Y or a rare earth element, and T is Fe or a combination of Fe and Co. This magnet is produced by compacting a mixture of a primary phase-forming master alloy and a grain boundary phase-forming master alloy, both in powder form, followed by sintering the compact. The primary phase-forming master alloy features columnar crystal grains of R.sub.2 T.sub.14 B with a mean grain size of 3-50 µm and contains 26-32 wt % of R. The grain boundary phase-forming master alloy consists of 32-60 wt % of R and the balance of Co or Co and Fe. Another form of his invention also focuses on the composition of permanent magnets, emphasizing the importance of the grain boundary-forming master alloy.
