摘要

本文结合实验和模拟,系统研究了放电等离子体烧结(spark plasma sintering, SPS)制备自钝化钨合金(self-passivation tungsten alloys, SPTAs)块体时的温度场、电流场对其组织均匀性的影响,建立烧结温度、时间、电流密度与块体微观组织的关系。结果表明：不同尺寸SPTAs块体在SPS固结时的温度沿径向分布不均,致使测量温度远低于样品实际温度。结合显微组织表征,发现提高样品烧结时的电流密度可缩短烧结时间,对获得细晶、均质结构样品有积极作用,但需要考虑样品因径向温度梯度引起的晶粒尺寸差异。本研究可为大尺寸SPTAs块体的SPS制备工艺设计提供参考。

Abstract

In this paper, the effects of temperature and current fields on the homogeneity of self-passivation tungsten alloys (SPTAs) prepared by spark plasma sintering (SPS) were systematically investigated by combining experiments and simulations, and the relationships between sintering temperature, sintering time, current density, and the microstructure of SPTAs were established. The results show that the temperature of the SPTAs bulks with different sizes during SPS consolidation is unevenly distributed along the radial direction, resulting in the measured temperature being much lower than the actual temperature of the samples. Combined with the microstructure characterization, it is found that increasing the current density during sample sintering can shorten the sintering time, and has a positive effect on obtaining fine-grained and homogeneous microstructure, but it is necessary to consider the difference of grain size caused by radial temperature gradient. This study can provide a reference for the SPS preparation process design of large-sized SPTAs bulks.
