2. 研究领域介绍

1. 金属液态结构及凝固过程的研究:

 由于在工业活动中,绝大部分合金都要经历液态-固态成形的过程,其液态成分结构对其固态物理化学性能有着非常重要的影响。然而对于晶体特别是合金熔体结构的研究远远不能满足工业需要,其理论研究基础往往还停留在上世纪五十年代。这些物理模型仅唯像的给出金属熔体短程序结构的存在形式,而对合金各种成分的精准调控设计需要给出短程序更精确的模型理论。我们提出了一种以热力学平衡态最概然原子结构作为等效体系描述金属熔体短程序的理论模型——Lin-Tian模型,并进行了严格的实验验证(高温液态XRD)。该模型能够准确描述纯金属,二元匀晶合金,二元共晶合金和含金属间化合物的一般二元合金,并成功的解释了金属间化合物形核势垒的微观物理意义以及金属粘度随温度突变的机理。

2. 合金化元素影响铸铁石墨形态与元素球化能力参数:

  以Lin-Tian模型为基础,我们研究了不同添加元素与石墨团簇的相互作用,并定义了新参数元素球化能力,成功的用微观参数将球化元素,无关元素,反球化元素明显的分离。这说明很可能我们建立的模型接近了铸铁中元素影响石墨生长的本质。这给了我们一种通过成分预测产品蠕化率的方法。由于蠕墨铸铁优良的机械性能和导热性能,成为高端柴油发动机的最佳选择。但是其制备及其困难,犹如抛硬币每次都要立起来。现在的通用方法是采用德国的OCC技术,其核心完全掌握在德国相关企业手中,是名副其实的卡脖子技术。通过我们研发的成分-蠕化率在线专家测控系统,有望完全打破国外在该领域的垄断。

3. 表面合金设计及制备:

 我们通过设计加实验验证的方法,成功制备了两种用于氢能源电池的高效单原子催化剂。采用铸造退合金加气氛热处理的方法,将贵金属的用量减少到之前的百分之10以下,催化性能略有提高,极大地降低了氢电池的生产成本。

4.量子元器件原理及性能改进:

  伴随着计算机科技的发展,二十世纪末进入了科技与信息爆炸式发展的时代,但是在计算机理论越来越成熟的今天,人们逐渐认识到传统意义的计算机在运算速度和体积上的严重不足,于是在理论上产生了量子计算机的构想 —— 一种基于量子效应元器件而并不局限于二进制运算的新型计算机,我们已经实现了稳定量子开关制备,现在试图对它的基本工作原理进行诠释,以达到改进原有量子元器件的目的,并已经取得了一定突破。
