Heinz Maier-Leibnitz 研究堆（FRM II，慕尼黑附近的加兴）设计并制造了新型拉伸装置。除了拉应力和压应力外，还可以施加扭转应力。独特的欧拉摇篮型设计（omega、chi 和 phi 轴）允许相对于散射矢量定向应力轴。这些拉伸装置在我们的中子衍射仪上的应用可以对机械负载下的结构变化进行各种研究，例如。晶体织构演化、应力引起的相变或晶格膨胀以及机械响应的各向异性。 (C) 2013 Elsevier B.V. 保留所有权利。
Novel tensile rigs have been designed and manufactured at the research reactor Heinz Maier-Leibnitz (FRM II, Garching near Munich). Besides tensile and compressive stress, also torsion can be applied. The unique Eulerian cradle type design (omega, chi, and phi axis) allows orienting the stress axis with respect to the scattering vector. Applications of these tensile rigs at our neutron diffractometers enable various investigations of structural changes under mechanical load, e.g. crystallographic texture evolution, stress-induced phase transformations or lattice expansion, and the anisotropy of mechanical response.
