Accurate Determination of the Lattice of Beta-Titanium at 900°C.

Abstract

A UNIQUE and original method for determining the high-temperature lattice constant for the bodycentred cubic form of titanium was devised by Burger and Jacobs1. Their method consisted of using a 300-micron wire as a filament in a Lindemann-glass bulb, placing this bulb in the centre of a Debye-Scherrer camera and rotating the bulb while heating the titanium filament to about 900°C. The lattice constant arrived at by their original investigation was 3.32 A. © 1950 Nature Publishing Group.
