摘要
研究了不同烧结压力对WC-12%Co粗晶硬质合金金相组织结构及物理力学性能的影响。结果表明:合金能够在较低的烧结压力下达到高度致密化,随着烧结压力增加,合金的三项性能没有明显的变化;当烧结压力为2 MPa左右时,合金的抗弯强度和冲击韧性最高,且具有良好的综合性能。
Study was made on the effects of different sintering pressure on metallographic microstructure and physical and mechanical properties of WC-12%Co coarse grained cemented carbide.The results show that the cemented carbide can be highly densified at relatively low sintering pressure.With the increase of sintering pressure,three properties of the cemented carbide have no obvious change.When sintering pressure is about 2 MPa,both flexural strength and impact toughness of the cemented carbide are highest with good comprehensive performance.
