Fatigue strength test of casting material GS-20Mn5V
The Small-sample up and down fatigue test method was used to test the fatigue limit of casting GS-20Mn5V which is the most popular casting material in civil engineering. The symmetric tension-compression fatigue test was on the high frequency fatigue tester. Ten useful test values were obtained through twelve tests with standard specimens. The mean value of fatigue limit of GS-20Mn5V is 202.8MPa after a statistic of the test results. The test provides the available data for engineering application.

SR topography of plastically deformed Fe-Si bicrystals - observation in situ and post mortem
SR reflection topography was applied to study the interaction of slip dislocations with the grain boundaries in Fe-4at%Si bicrystals deformed by compression. Three experimental settings with either a white or monochromatic beam were used and the corresponding orientation contrast analysed. Dislocation transmission through the grain boundary was observed in bicrystals with favourable geometry of the slip systems.
