Ternary Magnesium-Lithium Base Constitution Diagrams and Magnesium Alloys of Low Alloy Additions
Abstract
This report summarizes the experimental work on the study of two independent subjects. The first part of the report describes the development and application of techniques for establishing phase boundaries in the magnesium- lithium-aluminum and magnesium-lithium-zinc ternary systems. Based primarily on microscopic examination, the tentative locations of phase boundaries at 700 degrees F are presented for these two systems. Additional work at 700 degrees F and also at 500 degrees F is in progress. The second part of the report summarizes the progress in experimental development of magnesium-base alloys with low alloy additions. The primary purpose of this investigation is to obtain alloys having a favorable combination of medium strength and high formability. A major portion of the development work was devoted to a continued study of magnesium-zinc-cerium alloys. Information is presented to demonstrate that an attractive combination of mechanical properties may be obtained over a reasonably wide range of zinc and cerium concentrations. Warm rolling of sheet, followed by a stress relieving heat treatment, produced the most favorable mechanical properties. Details of two successful procedures for introducing zirconium in magnesium are described.
