achieved with a composition of Mg-8.23 wt.% Sn-2 wt.% Nd. The compressive creep resistance of Mg-8.23 wt.%Sn-2 wt.% Nd alloy was much better than other alloys at 200 oC for applied load of 35 MPa......
or Ni3La, Ni5Y or Ni5La, Ni2P2Y or Ni2P2La. The properties of the Ni-P-RE alloy coating were improved greatly, for example, crystalline size became fine and compact, the free corrosion potential......
and the high rate dischargeability.The alloy with x=3 (Ho6Fe20Co3) had better discharge capacity,HRD and plateau pressure at discharge current density of 150 mA/g.关键词:......
of superalloy.The results showed that the degradation of cast K38 alloy critically was dependent on the cyclic frequency.The yttrium addition was beneficial to reducing scale-growth rate,improving......
addition,the(Mg61Cu28Gd11)99.5Sb0.5 glassy alloy exhibited lower creep rate sensitivity,creep compliance and milder retardation peak,indicating its higher creep-resistance and less relaxed......
and improved greatly the oxidation resistance of the alloy.关键词:......
