研究領域
納米金屬材料製備、微觀結構、力學性能。
科研項目
1. 發展製備塊體納米結構金屬材料的技術-動態塑性變形(DPD)
發展動態塑性變形技術,在金屬材料中引入納米尺度變形孿晶和納米晶粒,製備塊體納米混合結構材料。已在純Cu、Cu-Al合金、Cu-Zn合金、不鏽鋼和TWIP鋼等材料中成功製備由納米晶粒和納米尺度孿晶組成的塊體納米混合結構材料,並通過變形材料的後續退火製備綜合力學性能更好的由再結晶晶粒和納米孿晶組成的新型混合結構,其中納米孿晶作為強化項,再結晶晶粒作為韌化項,使材料同時具有高強度和高塑性。
2. 發展製備梯度納米金屬材料的技術-表面機械碾壓處理(SMGT)
發展表面機械碾壓技術,通過移動的球形刀頭,在高速旋轉的被處理金屬材料表層產生強烈剪下變形,在材料表層實現梯度納米結構。目前已在純Cu和不鏽鋼等多種材料實現梯度納米結構, 研究梯度納米結構樣品的力學性能及變形機理。
3. 提出通過孿生變形導致納米晶粒形成的機制
研究表明塑性變形引入的高密度孿晶將原始粗大晶粒細分為具有特殊晶體學取向的一維納米結構,隨應變增加這些一維納米結構(孿晶/基體層片)被位錯牆或二次孿晶分割成等軸的納米尺寸晶粒,從而使細化晶粒的尺寸減小到真正的納米量級。當高密度納米孿晶被剪下時,在剪下帶內形成納米晶粒。
獲獎及榮譽
“金屬材料表面納米化技術和機理”獲2009年遼寧省自然科學一等獎。
