friction peak has been found in iron at about lOOoK, and possibly in molybdenum at about 300Β°K. These internal friction peaks occur at temperatures corresponding to the ductile to brittle transition of these materials in slow tension tests. The possible role of hydrogen in causing the 100Β°K peak in
## Abstract The effects of yttrium additions on the oxidation behaviour of Feβ20Crβ5Al(wt%) alloys have been investigated in oxidation tests and cyclic heatingβelement tests at temperatures ranging from 1100 to 1400Β°C in air. Experimental results showed that the oxidation resistance of the alloys d
