退火的和加工硬化钯丝的拉伸性能被测量了。它为氢含量的函数。室温电介作为氢吸收的方法。测定了屈服应力、极限拉伸应力和最大应力的延伸率。它表明氢含量在相边界附近突然变化。在单相区,拉伸性质对氢含量的依赖用电子结构和应变硬化来说明。辅助实验证明电介吸收氢形成的β-相是产生应变硬化的原因。 Tensile properties of annealed and work-hardened palladium wires were measured. It is a function of hydrogen content. Room temperature dielectric as hydrogen absorption method. The yield stress, ultimate tensile stress and maximum stress elongation were measured. It shows that the hydrogen content suddenly changes around the phase boundary. In single-phase zones, the dependence of tensile properties on hydrogen content is illustrated by the electronic structure and strain hardening. Auxiliary experiments show that β-phase formed by the dielectric hydrogen absorption is the cause of strain hardening.
