transmission electron microscope.Structure evolution in the metallic glass was investigated in situ during continuous irradiation,where phase separation was observed after irradiation for 5 min......
evaluated precisely and relatively quickly. It is found evolution of carbides apparently occurs during tempering at high temperatures, and a two-step transformation mechanism is proposed for M7C3......
to porosity evolution were discussed. The proposed method can be applied to all cementbased materials with any leaching degrees. From the quantitative increased porosity results, we find that the CH......
Hydrogen Trapping Phenomenon at Grain Boundaries in a 18Ni Maraging Steel姚大平,陈文绣摘 要:<正> An investigation of the phenomenon ofhydrogen trapping at grain boundaries in 18 Nimaraging steel has been carried out by the thermalhydrogen evolution technique.Grain boundary on-ly acts as a trapping site of hydrogen at low temper-ature region,and the peak......
system is obtainedand the trend of evolution of dislocation distribu-tion in deformed metals is discussed simultaneously.No micromechanisms of dislocations are involvedin the discussion,therefore......
of the melt superheat treatment on microstructure evolution was discussed for the immiscible alloys. The microstructure development in ternary Al-Bi-Co alloys directionally solidified with different melt......
by the sequential layer annealing was discussed based on the structure evolution with the annealing temperature.The remnant polarization and coercive field of the C0.4S0.6 BTi film annealed at 800......
with increasing fatigue stress amplitude and advancing number of applied fatigue cycles. Observed increase of specimen surface hardening degree during fatigue causes an evolution of superficial mechanical......
were synthesized using rare-earth acetates as precursors. The effects of reaction temperature and time on the phase transition process of the UCNPs were systematically studied. Based on the evolution......
