    专家简介及报告摘要:

       徐万强博士本科毕业于河北科技大学, 于 1991 和 2002 年分别于西安理工大 学和新西兰的奥克兰大学(The University of Auckland)取得材料科学与工程硕士, 2007 年于澳大利亚的新南威尔士大学(The University of New South Wales)取得工 学博士学位。目前作为一名研究员在位于澳大利亚悉尼的新南威尔士大学材料科 学与工程学院从事材料科学与工程研究。 在过去几年内共在国际期刊发表论文 40 余篇,其中包括“Nature Materials”一篇, “ACTA Materials”五篇。 本次报告摘要如下

          Ultra-light weight alloys with high strength, ductility and corrosion resistance are desirable for applications in the automotive, aerospace, defence, biomedical, sporting and electronic goods sectors. Ductility and corrosion resistance are generally inversely correlated with strength, making it difficult to optimize all three simultaneously. Here we design an ultralow density (1.4 g/cm3) Mg–Li-based alloy that is strong, ductile, and more corrosion resistant than Mg-based alloys reported so far. The alloy is Li-rich and a solute nanostructure within a body-centred cubic matrix is achieved by a series of extrusion, heat treatment and rolling processes. Corrosion resistance from the environment is believed to occur by a uniform lithium carbonate film in which surface coverage is much greater than in traditional hexagonal close-packed.
