Super-strong Light Metals by Populous Dispersed Nano-elements

 

Xiaochun Li

Raytheon Chair in Manufacturing,

Professor of Mechanical and Aerospace Engineering,

University of California, Los Angeles (UCLA)

 

Abstract: Light metals are widely considered as green materials with tremendous potential to improve energy efficiency and system performance for numerous applications. However, conventional processing methods have reached limits in further improving the properties of magnesium. Our recent study shows that a remarkable enhancement of strength, stiffness, plasticity and high temperature stability can be achieved in light metals by populous dispersed nano-elements (e.g. nanoparticles and nano-platelets), delivering the super-high specific strength and modulus. Unprecedented uniform dispersion of high volume fractions of nanoelemtns is successfully achieved in light metal matrices. This approach of populous nanoparticle dispersion and strengthening paves a new way to enhance the performance of light metals to meet energy and sustainability challenges in today’s society.

 

拥有众多分散的纳米相的超强轻金属

李晓春

美国雷神制造讲座教授

机械和航天工程学教授

美国加州大学洛杉矶分校(UCLA

 

摘要:轻金属被广泛认为具有巨大的潜力,它是能够提高各种应用能源效率和系统性能的绿色环保材料。然而,传统的加工方法在进一步提高轻金属的性能时已经达到极限。我们最近的研究表明,轻金属的强度、刚度、可塑性和高温稳定性可以由众多分散的纳米元素(例如,纳米颗粒和纳米片)显著增强, 而且可以提供超高比强度和模量。在轻金属基体中,成功实现了前所未有的高体积分数的纳米元素的均匀分散。众多分散的纳米颗粒强化机制提供了一条新的能提高轻金属性能的途径,可以满足当今社会能源的需要和可持续发展的挑战。

 

 

3.讲座内容二

 

Scifacturing: Science Driven Manufacturing for Sustainable Future

 

Xiaochun Li

Raytheon Chair in Manufacturing,

Professor of Mechanical and Aerospace Engineering,

University of California, Los Angeles (UCLA)

 

Abstract: Scientific revolutions provided fundamental tools that powered and transformed manufacturing to induce profound social changes in the last centuries. The traditional pathway from science to manufacturing has reached its ceiling due to the slowdown of fundamental science revolution and saturation of traditional manufacturing technologies. Current manufacturing engineers are generally far away from fundamental science or even applied physics. This talk will discuss about perspectives, needs and challenges for a powerful paradigm shift towards scifacturing, where advanced manufacturing will be driven more directly and faster than ever by science in the 21st century. Some recent advances will be presented to illuminate the power of scifacturing for a sustainable future.
