制备具有高强度和低 W 含量 (<80 wt%) 的块状 WNiFe 合金具有挑战性。在这里,我们提出了一种策略,即送粉激光熔化沉积(LMD)来解决这个问题。 LMD 制备的 WNiFe (LMD WNiFe) 样品具有高机械强度和低 W 含量(50 和 75 wt%)。 LMD WNiFe 样品中的 W 颗粒均匀分布在基体 (γ) 中,其细颗粒尺寸约为液相烧结 (LPS) 制备的传统 93WNiFe 合金颗粒尺寸的五分之一。 50和75wt%样品的极限拉伸强度分别为1120和1316MPa,比LPS制备的93WNiFe合金(LPS 93WNiFe)高24.44和59.33%。这些结果提出了一种制备具有细小、均匀分布的 W 颗粒的低 W 含量、高强度 WNiFe 合金的有用策略。这一发现为 WNiFe 合金在增材制造中提供了新的潜在应用。
Preparing bulk WNiFe alloys with high strengths and low W content (<80 wt%) is challenging. Here, we present a strategy, powder-fed laser melting deposition (LMD), to solve this problem. The LMD-prepared WNiFe (LMD WNiFe) samples show high mechanical strengths and low W contents of 50 and 75 wt%. The W particles in the LMD WNiFe samples uniformly distribute in the matrix (γ), exhibiting fine particle sizes of approximately one-fifth of those of conventional 93WNiFe alloys prepared by liquid phase sintering (LPS). The ultimate tensile strengths of the 50 and 75 wt% samples are 1120 and 1316 MPa, respectively, which are 24.44 and 59.33% higher than those of the LPS-prepared 93WNiFe alloy (LPS 93WNiFe). These results suggest a useful strategy for preparing low-W-content, high-strength WNiFe alloys with fine, uniformly distributed W particles. This finding offers new potential applications of WNiFe alloys in additive manufacturing.
