U-FAST在先进材料研发中的应用

本文介绍了升级版的电场辅助烧结技术U-FAST(SPS)技术,该技术采用了现代电源技术,具有更快的加热速度,可以广泛的应用于先进材料的研发。如应用在烧结碳化物(WC-Co)、热电材料(PbTe)、Zr-Cu-Al-Nb(块状金属玻璃)、复合材料、透明陶瓷材料、生物材料、金刚石增加复合材料(EDC)等,并介绍了应用U-FAST工艺生产的特点。在较低温度和较短时间下开始烧结过程且不会产生任何不利的晶粒生长,使U-FAST技术成为生产纳米晶和亚微米材料的理想工艺,将电场辅助烧烧结技术提升到新高度。

U-FAST technology in research and development of advanced materials

This paper intruduces an upgraded field assisted sintering technology—U-FAST(SPS) equipment,which uses new generation pulses power technology and has very high heating speed,can be widely used in R&D of advanced materials.,such as sintered carbides(WC-Co),thermoelectric materials(PbTe),Zr-Cu-Al-Nb(bulk metallic glass),composite materials,ceramic materials,biological materials and diamond enhanced composite materials(EDC),etc.,and introduces the characteristics of U-FAST.The starting of the sintering process at a lower temperature and a shorter time makes the U-FAST technology an ideal tool for producing nanocrystalline and submicron materials without adverse grain growth.This electric field-assisted sintering technology will be promoted to new level by the FAST technology.
