爬 Super304H 奥氏体的钢的行为在 923973K 的提高的温度并且在 190210MPa 的应用应力被调查了。结果证明在 creep 变丑的明显的压力代表和激活精力分别地在不同温度从 16.2 ～ 27.4 并且从 602.1 到 769.3kJ/mol。这些高价值由于在脱臼之间的一个相互作用暗示一个阀值压力的存在并且 Cu 富有猛抛在期间爬变丑。creep 机制与脱臼爬被联系由矩阵格子散开管理了。阀值压力的起源主要被归因于在矩阵导致由的连贯紧张 Cu 富有猛抛。理论上估计的阀值压力从 Cu 富有猛抛与试验性的结果相当同意。
Currently, the topological behavior of materials is a hot topic in condensed matter physics. As a new class of topological quantum states, Weyl semimetals have attracted extensive interest. Taking the pyrochlore iridates A2Ir2O7(A=Y or rare earth element) as an example, we discuss the novel properties of Weyl semimeta…
