Title: Innovations in Aluminum Alloys by Inventor Donald Webster
Introduction
Donald Webster is a notable inventor based in Saratoga, California, with a remarkable portfolio comprising 10 patents. His work primarily focuses on aluminum-based products and alloys, highlighting his commitment to enhancing material properties for various applications.
Latest Patents
Webster's recent innovations include the development of aluminum-lithium, aluminum-magnesium, and magnesium-lithium alloys. His aluminum-based products incorporate 0.5 to 4.5 wt% lithium while ensuring that the alkali metal impurity elements—sodium, potassium, rubidium, and cesium—do not exceed 1 ppm. This formulation results in products that can be aged to a peak condition, achieving a grain boundary region devoid of liquid phase eutectics formed by sodium and potassium, which typically contribute to embrittlement at room temperature. Furthermore, Webster's aluminum-magnesium alloys demonstrate significant improvements in elongation and fracture toughness when aged, with a lithium-free composition containing at least 0.5 wt% magnesium and low levels of alkali metals.
