研究领域:

  纳米金属材料制备、微观结构、力学性能。

承担科研项目情况:

  1. 发展制备块体纳米结构金属材料的技术-动态塑性变形(DPD

  发展动态塑性变形技术,在金属材料中引入纳米尺度变形孪晶和纳米晶粒,制备块体纳米混合结构材料。已在纯CuCu-Al合金、Cu-Zn合金、不锈钢和TWIP钢等材料中成功制备由纳米晶粒和纳米尺度孪晶组成的块体纳米混合结构材料,并通过变形材料的后续退火制备综合力学性能更好的由再结晶晶粒和纳米孪晶组成的新型混合结构,其中纳米孪晶作为强化项,再结晶晶粒作为韧化项,使材料同时具有高强度和高塑性。

  2. 发展制备梯度纳米金属材料的技术-表面机械碾压处理(SMGT

  发展表面机械碾压技术,通过移动的球形刀头,在高速旋转的被处理金属材料表层产生强烈剪切变形,在材料表层实现梯度纳米结构。目前已在纯Cu和不锈钢等多种材料实现梯度纳米结构, 研究梯度纳米结构样品的力学性能及变形机理。

  3. 提出通过孪生变形导致纳米晶粒形成的机制

  研究表明塑性变形引入的高密度孪晶将原始粗大晶粒细分为具有特殊晶体学取向的一维纳米结构,随应变增加这些一维纳米结构(孪晶/基体层片)被位错墙或二次孪晶分割成等轴的纳米尺寸晶粒,从而使细化晶粒的尺寸减小到真正的纳米量级。当高密度纳米孪晶被剪切时,在剪切带内形成纳米晶粒。
