微量Mg对纯Ag的性能影响

Influence of trace magnesium on properties of pure silver

    摘要
  • 摘要: 在99.995%Ag中添加8×10-5Mg制成99.99%纯Ag,进行机械性能测试试验.当ε=98%时,在25℃下保存200d,其强度和硬度稳定不变.即在99.995%的高纯Ag中存在有微量镁,使Ag在结晶过程中出现少量Ag溶Mg的固溶体颗粒,细化Ag的晶粒,晶界增多,变形抗力增大.起到强化和稳定机械性能的作用.

     

    Abstract: A 99.99% silver material is manufactured by adding 8×10-5Mg to the 99.995% Ag.The test measurement of mechanical properties for this material shows that the strength and hardness of the silver kept at 25℃ for 200 days do not change with time if ε =98%.By adding trace magnesium to 99.995% silver,the pellets of solid solution of Mg dissolved by Ag are produced with fine crystal grains of Ag,increased crystal interfaces and higher strength.
