Abstract

The effect of heat treatment at 1273 K for 1 week on the first hydrogenation of body-centered cubic (BCC) 52Ti-12V-36Cr alloy with 4 wt pct Zr₇Ni₁₀, 4 wt pct Zr, and 2.2 wt pct Zr additives was investigated. Upon heat treatment, the relative abundances of BCC, C15-type Laves phase, and α-Ti drastically changed. Their chemical composition also changed. This resulted in the elimination of incubation time and faster first hydrogenation kinetics but also an important reduction of total hydrogen capacity by 40 pct.

热处理对含Zr和Zr-Ni添加剂的BCC 52Ti-12V-36Cr合金的晶体结构，微结构和氢化行为的影响

摘要

热处理在1273 K中1周的体心立方（BCC）52Ti-12V-36Cr合金的第一氢化用4％重的Zr的效果₇的Ni ₁₀，4重％的Zr，和2.2重％的Zr添加剂WAS调查。热处理后，BCC，C15型Laves相和α-Ti的相对丰度发生了急剧变化。它们的化学组成也改变了。这导致温育时间的消除和更快的第一次氢化动力学，而且总氢气容量的重要减少了40 pct。
