Abstract:  
The early work in x-ray stress measurements in this country and in Germany was done on iron and steel with application to such problems as arise in welding, gun construciton, fatigue studies, etc. More recently it has been applied to aluminum alloys in connection with casting and forming problems. Other work has now extended the method to cartridge brass with special reference to the season cracking problem. Thus the field of application for x-ray residual stress measurements has been increasing. Not only has the number of metals on which measurements are being made increased, but the condition of the metal now presents less of a barrier to useful measurements than it previously did. The measurements on steel are usually made on metal with the grain size for maximum sharpness of the diffracted cones. However, Frommer and Lloyd (1)*** have been able to make successful measurements on cast aluminum with large grains and it has been the experience of the present authors that useful measurements may be made on heavily cold worked cartridge brass with its very fine grained x-ray structure.
