Institute of Metals Division - Heat Treatment and Mechanical Properties of Ti-Mo Alloys

IN a previous series of papers, the results of studies made on various types of high purity base titanium alloys were presented. Included in this work were the Ti-Mn' and Ti-Cu' alloys, representative of sluggish and active eutectoid systems, respectively. The present paper gives the results of a simi- lar study made on Ti-Mo alloys as an example of a ß-isomorphous alloy system. Experimental Procedures Alloy Preparation—Six ½-lb ingots were prepared from iodide titanium and high purity molybdenum stock. The ingots were arc melted in a water-cooled copper crucible under an argon atmosphere. Each ingot was melted at least twice to insure homogeneity and complete solution of the molybdenum. This was done by inverting the ingot in the crucible and remelting completely.
