日本名古屋工业技术试验所开发出在高速下出现超塑性的晶须增强铝基复合材料。此种材料的变形量每0.5秒为2倍,最高延伸率可达600％。 该复合材料采用6061铝合金作为基材,氮化硅粒子作为增强材料。不需进行中间加工热处理,可由挤压后的材料直接切出所规定尺寸的试验片。由 Japan’s Nagoya Industrial Technology Laboratory developed superplastic whisker reinforced aluminum matrix composites at high speeds. The deformation of this material is 2 times every 0.5 seconds, the maximum elongation of up to 600%. The composite material uses 6061 aluminum alloy as a substrate, silicon nitride particles as a reinforcing material. Without the need for intermediate processing heat treatment, the extruded material can be directly cut out of a predetermined size of the test piece. by
