具有高强度、高韧性和高温稳定性的钨合金在极端条件下是迫切需要的。纳米工程的钾泡（5-50 nm）是一个迷人的策略，以加强这些性质。然而，这种纳米钾泡目前只能通过挤压和拉丝工艺在钨丝中获得。本文报道了一种采用铝钾硅（AKS）掺杂和火花等离子烧结（SPS）相结合的工业应用工艺制备的钾内和钾间纳米气泡增强体钨，该材料具有理想的强度和显著的韧性，以及高的抗热震性。aks掺杂将K- al - si - o颗粒掺入W晶粒内，SPS的快速高温烧结使K- al - si - o颗粒产生纳米K泡，并使K泡保持在W晶粒内。我们的k泡强化钨材料在高温应用中显示出很高的潜力。这种策略也可能适用于其他难熔金属，如钼。
Tungsten alloys with high strength, high toughness and high-temperature stability are strongly desired in extreme conditions. The nanoengineering of potassium bubbles (5–50 nm) is a fascinating strategy to strengthen these properties. However, such nano potassium bubbles can only be acquired in tungsten wires through swaging and drawing process till now. Here, we report an intra- and inter-potassium nano-bubbles strengthened bulk tungsten fabricated via an industrially applicable process combining aluminum-potassium-silicon (AKS) doping and spark plasma sintering (SPS), which exhibits desirable strength and remarkable toughness, as well as high thermal-shock resistance. The AKS-doping incorporated the K-Al-Si-O particles inside the W grains and the rapid high-temperature sintering of SPS produced the nanometer K bubbles from the K-Al-Si-O particles and kept the K bubbles inside the W grains. Our K-bubble strengthened tungsten material displays high potential in high-temperature applications. This strategy is also potentially applicable to other refractory metals such as molybdenum.
