Bachelors Theses and Reports, 1928 - 1970

The tin alloys of tellurium are extremely hard and have very great tensile strength. It was thought that the reduction of the rate of grain growth of tin with the addition of tellurium accompanied this hardening and strengthening and such way found to be true.
