Introduction

Nack J Kim is a notable inventor based in Florham Park, NJ (US), recognized for his contributions to the field of materials science. He holds two patents that showcase his expertise in developing advanced alloys with enhanced properties.

Latest Patents

One of his latest patents is focused on rapidly solidified superplastic aluminum-lithium alloys. This innovative process involves subjecting an aluminum base lithium-containing alloy to at least one overaging treatment and multiple rolling passes. The resulting alloy features ultrafine grain sizes, with a significant number of grains having boundaries pinned by the precipitation of the Al3Zr phase. This alloy demonstrates an impressive elongation greater than 500% at temperatures above 500°C and strain rates exceeding 4 x 10^-2 /s. Another significant patent by Kim details a method for forming high-strength, tough, corrosion-resistant steel. This process involves heating an alloy steel composed of iron, carbon, manganese, and chromium to about 1150°C to create a stable homogeneous austenite phase. The steel is then controlled rolled at temperatures between 900°C and 1100°C, followed by rapid cooling and quenching, with optional tempering to enhance toughness.
