With a total of 2 patents to his name, McKay's work has implications for various applications in technology and engineering.
Latest Patents
One of McKay's latest patents focuses on a hysteresis alloy. This innovative alloy consists essentially of 13-18% nickel, 7-11% aluminum, 0.5 to 10% cobalt, 0.1 to 2% silicon, and the remainder substantially all iron. The production process involves heating the alloy composition to a temperature of about 1650°C or above to form a melt, which is then cast in a suitable mold. After solidification, the casting is heated to approximately 1150°C and held at that temperature to ensure uniform heating. It is then cooled at a rate of about 300°C per minute. The parts undergo aging to produce uniform magnetic properties throughout the casting. The resulting magnets exhibit stable magnetic properties with typical values of Br = 10,000, Hc = 150, and BH max = 0.85. A further improvement can be achieved through a second stage heat treatment, enhancing the properties to Br = 9,500, Hc = 230, and BH max = 1.2. These characteristics make the alloy particularly well-suited for hysteresis torque-producing devices.
