Branch Elimination During Heat Treatment of Titanium Alloys With a Colony-Alpha Microstructure (Preprint)

Abstract

The kinetics of the dissolution of lamellar branches in an alpha-beta titanium alloy with a colony-alpha microstructure were determined using a series of heat treatments at 900 and 955 degrees C. The experiments revealed that the branch recession rate was constant. An approximate diffusion analysis was developed to describe the diffusion process, and corresponding model predictions showed good agreement with measurements.
