宋岩的学术成绩

1． 合金力学性质的计算与合金设计
成功的将电子结构理论应用于结构钛合金和医用钛合金力学性质的计算和合金设计，系统地计算了金属的弹性模量和理论强度（Phys. Rev. B 59, 1422, 1999; Phil, Mag. A 81, 321, 2001）, 研究了合金元素对合金相稳定性，弹性模量及强度的影响（Phil，Mag.A 82.1345,2002）,并将理论研究结果应用于设计低弹性模量/高强度的医用钛合金(J.Computer. Aided Mater.Design 6,355,1999)
2． 镁氢化物储氢性能的计算与预测
应用第一性原理方法，研究了镁基储氢合金的储氢性能，计算了合金元素对MgH2稳定性的影响（Phys.Rev.B 69,094205,2004）,预测了MgH2一种新的亚稳相的存在(Phys.Rev.Lett.审稿中),在理论研究的指导下,成功地在实验上将MgH2的分解温度从430°降至150°（Int.J.Hydrogen Energy 29,73,2004）, 为MgH2作为储氢载体的实用化取得了突破性进展。
3．Li-N-H体系键相互作用机制的研究
系统地计算了Li-N-H体系，Li2NH，LiNH2，LiH和NH3的电子结构和体系的总能量，应用谐振子振动模型。首次在理论上确定了Li-N，N-H键间的相互作用强度，在此基础上提出了LiNH2分解反应机制模型,从理论上澄清了实验上关于LiNH2分解反应机制（一次直接分解反映〈Nature 420，302，2002〉和二次过渡分解反应〈J.Phys.Chen.B 108.7887,2004〉）的争论,为进一步的合金设计打下了坚实的基础.
