    摘要:

    以Inconel718氣霧化預合金粉末為原料,采用金屬注射成形(MIM)工藝制備Inconel718合金材料。研究Inconel718合金燒結、熱等靜壓(HIP)、熱處理對合金顯微組織、密度和力學性能的影響。結果表明:經1275 ℃燒結后,燒結體的相對密度達到98%。燒結體經HIP處理后,達到全致密。經燒結+HIP+熱處理后,組織彌散析出了大量的γ″相和γ′相,其室溫抗拉強度為1250 MPa,延伸率為21.7%;650 ℃抗拉強度為1177 MPa,延伸率為16.6%,其達到或超過了同牌號鍛造合金的性能。

    Abstract:

    Effects of sintering temperature, hot isostatic pressing(HIP)and heat-treatment on the microstructure, density and mechanical properties of Inconel718 alloy prepared by metal injection molding were investigated. The results show that the sintered alloy with a relative density of 98% can be achieved at 1275 °C. After HIP process, full density was achieved. After heat-treatment, a large amount of γ″ and γ′ phase were precipitated which increases the tensile strength and decreases the elongation of the alloy. The tensile strength and elongation were 1250 MPa and 21.7%, respectively, at room temperature, and 1177 MPa and 16.6% at 650 °C respectively, which are comparable with or superior to those of the wrought alloy.
