用核化法制造毫微结构微合金结构设计似乎有两个截然不同的发展趋势。一些应用需要大单晶;一些应用需要极精细的微结构。H.Gleiter所做的压缩原子团的研究表明,有可能获得几毫微米的晶粒尺度。虽然获得毫微结构材料的方法多种多样,但多数方法是压缩细粉末。而...
Fabrication of Nanostructures by Nucleation The design of micro-alloy structures seems to have two distinct trends. Some applications require large single crystals; some applications require very fine microstructures. H. A study by Gleiter for condensed radicals shows that it is possible to obtain grain sizes of a few nanometers. Although there are many ways to obtain nanostructured materials, most methods compress the fine powder. and...
