本文用同步辐射X射线原位衍射法测定了一种新开发的多功能β钛合金Gum metal的单晶弹性常数。结果表明，该合金的（C_（11）-C_（12））约为33 GPa，大于以前的预测值。因此，这种材料似乎需要大的局部应力集中，以便通过理想的剪切变形。X射线衍射分析还表明，胶金属在拉伸载荷期间经历应力诱导的相变。
The single-crystal elastic constants of a recently developed multifunctional β titanium alloy, Gum metal, have been obtained with the aid of in situ synchrotron X-ray diffraction. Results indicate that (C11-C12) is approximately 33GPa in this alloy, which is larger than previously predicted. Consequently it appears that this material would require a large local stress concentration in order to deform via ideal shear. X-ray diffraction analysis also suggests that Gum metal undergoes a stress-induced phase transformation during tensile loading.
