Abstract:
The results of two and a half years of experimental work are presented in the form of conclusions, five tables and nine graphs. Also included are photographs and diagrams of the experimental set up. Results of R vs T for Cb show agreement with others up to 1000C results can be expressed by RsubT R OC 1 - aT - bT squared which differs from linear relationship obtained elsewhere. Because of quenching some kind of defects can be retained in Cb containing certain amount of interstitial impurities. A minimum dose of 1.10 to the 17th power neutronssq cm is necessary to produce a measurable increase in the hardness of polycrystalline Cb. Author
