With a total of 5 patents to his name, Rezhets has demonstrated a commitment to innovation and engineering excellence.

Latest Patents

One of his latest patents involves the creation of creep-resistant magnesium alloy die castings. This family of die castable, creep-resistant magnesium alloys is designed for high-temperature structural applications, such as automotive engines and transmission cases. These alloys contain between 3% and 6% aluminum, 1.7% and 3.3% calcium, and up to 0.2% strontium. They have shown a remarkable 25% greater tensile and compressive creep resistance compared to AE42, a commercial aluminum, rare earth-containing magnesium alloy, while also exhibiting corrosion resistance comparable to AZ91D. Additionally, these alloys are estimated to be more cost-effective than AZ91D and possess good castability in metal molds used in permanent mold casting and die casting.

Another significant patent by Rezhets is a powder metallurgy process for producing multiphase nickel-aluminum-titanium intermetallic alloys. This innovative process allows for the creation of near-net shape, near-theoretical density structures by employing pressureless sintering techniques. The method involves blending a brittle aluminide master alloy powder with ductile nickel powder to achieve the desired composition. Following cold compaction of the powdered mixture, the compact undergoes liquid phase sintering, ensuring maximum degassing, elimination of surface nickel oxide, homogenization of the alloy, and complete densification.
