revolutions both at room temperature and at 573 K. Microstructural observation and analysis from Hall-Patch relationship could reveal that grain refinement and grain boundaries strengthening are the main...); W-25Re alloy; microstructure; Hall-Patch relationship; microhardness evolution 1 Introduction Tungsten-25% rhenium (mass fraction) (W-25Re) alloy has been usually manufactured into wire......
; Stress-strain relationship of unsaturated cohesive soil MEI Guo-xiong(梅国雄)1, CHEN Qi-ming(陈启明)2, JIANG... by conducting undrained triaxial compression tests using the remolded soil samples. The test results show that the stress-strain relationship of unsaturated cohesive soil is still hyperbolic. The values......
