The Effect Of Boron On The Hardenability Of Steel, William J. Foy
The Effect Of Boron On The Hardenability Of Steel, William J. Foy
Bachelors Theses and Reports, 1928 - 1970
Many attempts have been made to improve iron and steel and their alloys by the addition of boron. The results obtained were not encouraging for the reason that the amount of boron used, generally from 0.2 to 2.0 per cent is altogether too high. This percentage of boron renders the product hard and brittle and of late the experiments with boron in this connection have been practically abandoned.

An Experimental Investigation Of The Age Hardening Of Nickel With Boron, Willard M. Boam
Bachelors Theses and Reports, 1928 - 1970
Since 1911, at which time, the age hardening phenomenon of duralumin was discovered by Film, much research has been carried on investigating the various alloy systems. The successful application of age hardening to the copper aluminum system (duralumin) has indicated the possibility of hardening practically all the metals in the same way.
