液相烧结钨合金(93W)在加载22小时后,其应力才趋于稳定,0-22小时之间,应力随时间的变化率在200MPa附近出现极大值。出现这种特殊应力驰豫规律的本质是合金的特殊相结构、滞弹性变形以及蠕变。
The stress of the liquid-phase sintered tungsten alloy (93W) tended to be stable after being loaded for 22 hours. The maximum rate of stress change with time was found around 200 MPa between 0 and 22 hours. The emergence of this special law of stress relaxation is the nature of the special alloy phase structure, the deformation of the anelastic deformation and creep.
