Ti-Zr合金体系在总浓度范围内均为同晶。由于Ti和Zr的相干中子散射幅值分别为负和正，在成分ti0.676 zr0.324处可以得到中子零散射合金。在0.08 MPa的氘气气氛下，采用机械合金化（MA）法制备了A (Ti0.676Zr0.324) d0.31非晶合金。对比发现，在2.0 MPa的氘气气氛下，Ti和Zr粉末的MA形成纳米晶（Ti0.676Zr0.324） d1.54合金，该合金由tih2和zrh2结晶化合物组成。
The Ti–Zr alloy system is isomorphous over the total concentration range. A neutron zero-scattering alloy can be obtained at the composition Ti0.676Zr0.324because of negative and positive coherent neutron scattering amplitudes of Ti and Zr respectively. A (Ti0.676Zr0.324)D0.31amorphous alloy was synthesized by mechanical alloying (MA) under a deuterium-gas atmosphere of 0.08 MPa. In contrast, it is found that the MA of Ti and Zr powders under a deuterium-gas atmosphere of 2.0 MPa forms a nano-crystalline (Ti0.676Zr0.324)D1.54alloy, which is composed of TiH2and ZrH2crystalline compounds.
