Latest Patents

One of his latest patents focuses on copper alloys having improved softening resistance. This invention provides a method for manufacturing copper base alloys that resist thermally induced softening. The alloy composition is carefully selected to undergo either a peritectic or eutectic transformation during cooling. The solidification rate is controlled to ensure that the second phase forms as a uniform dispersion of a relatively small dispersoid, which inhibits recrystallization and results in an alloy that is less susceptible to softening at elevated temperatures.

Another significant patent relates to a process for improving the electrical conductivity of copper-iron-nickel alloys. These alloys are particularly useful in electronic applications due to their low coefficients of expansion and high thermal conductivities. The composition consists of 10% to about 80% copper, with the balance being iron and nickel. The ratio of iron to nickel is maintained between 1.5:1 and 2.0:1, with preferred ratios ranging from 1.6:1 to 1.9:1. The process includes casting the alloy and treating the iron-nickel phase to minimize its surface volume, which may involve speroidizing the iron-nickel phase or applying an electromagnetic stirring force during casting.
