【摘要】以MoS i2为试验对象,详细研究了等离子火花放电烧结法(SPS)和热压烧结法(HP)对其显微组织和力学性能的影响。结果表明,在相同的烧结温度下,SPS烧结制备的MoS i2材料,其显微组织比热压烧结要细小得多,且S iO2含量较少,纯度较高,致密度比热压烧结提高7%,显微硬度提高3倍以上,抗压强度提高2倍左右,但断裂韧性比后者稍低。更多还原

【Abstract】 MoSi₂ have been fabricated by spark plasma sintering and hot press sintering successfully.Microstruction and mechanical properties of MoSi₂ were determined.The experimental results showed that under the same temperature,the microstruction of MoSi₂ fabricated by SPS is much finer than that by HP,the inclusion of SiO₂ is less than that by HP,the soudness is higher by 7%,vicker hardness is over thrice of the latter,the condensation intension is about twice of the latter,but the fracture toughness is less than the latter.更多还原
