| 内容記述 | Pure tungsten plates with three kinds of manufacturing processes, i.e., ITER-Grade tungsten, cross-rolledtungsten with a moderate rolling ratio and another cross-rolled tungsten with a high rolling ratio, were evaluatedby the Vickers hardness test, tensile test at room temperature and 500 °C, and micro pillar test. The Vickershardness test results showed that the hardness value of all types of the tungsten plates was 410–430 Hv and nosignificant data dispersion was identified. However, the tensile test showed comparably large data dispersion,which was particularly drastic at room temperature. In parallel, to determine the effect of the specimen cutlocation thorough the plate thickness direction (S-Direction), micro pillar tests were conducted. Although therewere some data dispersion, test results showed plastic deformation and no marked effect of the cut location wasidentified. It is therefore believed that the specimen cut location did not affect the data dispersion identified inthe tensile test. Alternatively, the probable explanation for such large dispersion is partial detachment of thesurface bulk structure. Such specific microstructure can make crack paths more complicated, resulting in thedata dispersion。 | |||||
