regeneration of a suction-cast Ti36Zr40Ni20Pd4 quasicrystal.It was found that only through hot vacuuming the quasicrystal could be refreshed from air-flow poisoning to absorb deuterium in two cycles.During... by eight-stage desorption at different temperatures.After the second desorption,the quasicrystal phase remained in a small volume,as though the desorption temperature was beyond the crystallization......
Investigation on the icosahedral quasicrystal phase in Mg70.8Zn28Nd1.2 alloy张金山,严杰,韩富银,梁伟,许春香,周翠兰摘 要:Mg70.8Zn28Nd1.2 (mole fraction) alloy containing icosahedral quasicrystal phase (I-phase) was prepared under conventional metal casting conditions. The microstructure, phase constitution and phase structure of the alloy were investigated by means......
