New nickel‐base superalloys with higher temperature capability are required for future, more efficient gas turbine engines. In designing such alloys, careful consideration is required of the elemental concentrations to ensure a suitable balance of properties is obtained. Herein, the phase equilibria and microstructural stability of new nickel‐base superalloys with varying Al:Nb ratio are assessed via long‐term thermal exposures at 700 °C. The alloys are analyzed using scanning and transmission electron microscopy, X‐ray diffraction, differential scanning calorimetry, and Vickers hardness testing, with the results rationalized through mechanical property predictions based on strong‐ and weak‐pair dislocation coupling mechanisms. The alloys are shown to have greater thermal stability than Inconel 718 and exhibit a pronounced hardening effect after thermal exposure. Herein, their ability for controlled age hardening and potential ease of processing is highlighted in the results.

Until recently, scholars paid relatively little attention to chapter 23 of Leviathan, in which Hobbes discussed “the public ministers of sovereign power.” In the past few years, however, political theorists have used chapter 23 extensively in discussions of Hobbes’ concept of the state. But what was the significance of the chapter in its own time? This article suggests it served two purposes. First, it allowed Hobbes to bolster and elaborate arguments made elsewhere in Leviathan. Second, it responded to 1640s debates between royalists and parliamentarians over the role of subordinate magistrates in a polity. By the time Leviathan was published in 1651 these debates were no longer pressing, which explains the chapter’s rapid descent into obscurity. Nonetheless, recovering this polemical context helps to understand the genesis of this small but significant part of Hobbes’ political thought.

This book traces the beginnings of a shift from one model of gendered power to another. Over the course of the seventeenth and early eighteenth centuries, traditional practices of local government by heads of household began to be undermined by new legal ideas about what it meant to hold office. In London, this enabled the emergence of a new kind of officeholding and a new kind of policing, rooted in a fraternal culture of official masculinity. London officers arrested, searched, and sometimes assaulted people on the basis of gendered suspicions, especially poorer women. Gender and Policing in Early Modern England describes how a recognisable form of gendered policing emerged from practices of local government by patriarchs and addresses wider questions about the relationship between gender and the state.
