碳化钽的高温烧结特性及致密化机制研究

Key Points

• The central aim is to investigate the high-temperature sintering characteristics and densification mechanisms of tantalum carbide.
• Analyzed the sintering behavior of tantalum carbide under varying temperatures and dwell times.
• Examined the effects of additives on the density and microstructure of sintered tantalum carbide bodies.
• Utilized scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques for analysis.
• Identified the densification mechanisms including particle rearrangement, neck growth, and grain growth during high-temperature sintering.
• Optimal sintering parameters significantly increased the density and improved microstructure and mechanical properties of tantalum carbide.
