摘要

耐火合金的使用温度高于现有的镍基超级合金(例如,⪆1100 °C),人们对耐火合金重新产生了兴趣。本研究综述了在广泛的温度(≈860 °C < T < ≈1760°C)和应变率(≈10-9 s-1 < ε˙ < ≈10-1 s-1)范围内测得的铌合金高温组织响应。然而,现存数据稀少,要做出明智的材料选择决定,需要用构成表达式进行内插和可靠的外推。描述蠕变寿命的 Larson-Miller 参数方法对材料在最高温度和最低应变率下的反应进行了保守估计,而 Sellars-Tegart 模型则用一个单一的通用方程描述了稳态蠕变和高温拉伸试验数据。我们提出了基于这两种模型组合的最小流动应力,用于设计考虑,以解决单独应用其中一种模型可能导致强度预测过高的问题。这项工作强调了这样一个事实,即耐火合金在应用所关注的温度范围内表现出应变速率敏感的流动强度。本文讨论了合金、热机械加工和杂质含量的作用,并强调了一个事实,即除了碳化物沉淀强化合金 D-43 外,这些高级铌合金都具有 1 级(A 级)溶质拖曳控制蠕变行为。此外,高温强度与合金熔点密切相关。

A unified model of tensile and creep deformation for use in niobium alloy materials selection and design for high-temperature applications

There is renewed interest in refractory alloys that possess higher service temperatures than incumbent Ni-based superalloys (e.g., ⪆1100 °C). This study provides a review of the high-temperature constitutive responses of Nb-alloys measured over a wide range of temperatures (≈860 °C < T < ≈1760 °C) and strain rates (≈10–9 s-1< ε˙ < ≈10–1 s-1). Nevertheless, the extant data is sparse and informed materials selection decisions require constitutive expressions to interpolate and reliably extrapolate. The Larson-Miller parameter approach to describe creep-life provides a conservative estimate of material response at the highest temperatures and lowest strain rates, whereas the Sellars-Tegart model describes both steady-state creep and high-temperature tensile test data with a single, universal equation. A minimum flow stress based on the combination of these two models is proposed for design considerations to address the overprediction of strength that can arise from applying one or the other independently. This effort highlights the fact that refractory alloys exhibit strain rate sensitive flow strengths in the temperature range of interest for applications. The roles of alloying, thermomechanical processing, and impurity levels are discussed, and highlight the fact that these advanced Nb-alloys evidence Class 1 (Class A) solute drag controlled creep behavior, except the carbide precipitation strengthened alloy, D-43. In addition, the high-temperature strengths are confirmed to be strongly correlated with alloy melting point.

期刊介绍: Materialia is a multidisciplinary journal of materials science and engineering that publishes original peer-reviewed research articles. Articles in Materialia advance the understanding of the relationship between processing, structure, property, and function of materials. Materialia publishes full-length research articles, review articles, and letters (short communications). In addition to receiving direct submissions, Materialia also accepts transfers from Acta Materialia, Inc. partner journals. Materialia offers authors the choice to publish on an open access model (with author fee), or on a subscription model (with no author fee).
