Summary
A study was made, by electron-microscope fractography of the effects of composition and conditions of cooling from the sintering temperature on the character of rupture of W-Ni-Fe heavy alloys. It has been established that the change in the mechanism of rupture from brittle to tough is due to structural changes in the alloy linked with the aging process.
