Abstract
The dispersion-strengthening of lead has been discussed as a means of improving the properties of lead and conventional lead alloys.
Techniques are described for the production of dispersion-strengthened lead using lead oxide dispersions. Remarkable improvements in properties have been observed, notably tensile strength of up to 5 times that of lead and greater than that of any conventional lead alloy, superior strength at elevated temperature, high thermal stability and resistance to grain growth, the development of “springiness” and the retention of the corrosion-resistance characteristic of lead. It is suggested that a re-appraisal of the applications of lead may now be opportune and some possible uses of dispersion-strengthened lead are discussed.
