The perplexing case of Creasey v Breachwood Motors Ltd [1992] BCC 638 triggered important debates which helped to clarify the ―sham‖ exception to the Salomon principle. However arguments for a ―Creasey extension‖ to the categories when the courts will deviate from Salomon have not been accepted.
Ti-V基固溶体型储氢合金吸放氢性能的研究-学位-万方数据知识服 …
Ti-V基固溶体型储氢合金由于较大的储氢量和良好的吸放氢动力学性能而被认为是最有希望成为燃料电池车用储氢材料之一。通常情况下,高V含量的Ti-V基合金的放氢平台压低于一个大气压。本文定义放氢曲线在1 atm压力处的储氢量与合金最大吸氢量的差值为合金的有效放氢量。
钒是强化 fcc 和 bcc 高熵合金的最佳元素,Acta Materialia - X-MOL
适用于 fcc 和 bcc HEAs 的无参数理论使这一发现合理化,预测了一系列 fcc 和 bcc 合金的强度,与实验在定量和定性上一致。 在 fcc 类中,分析说明了为什么新发现的 NiCoV 和 Ni0.632V0.368 合金的强度远高于任何其他 fcc 合金,并且预计会达到最高。
用于储氢的无 V BCC 结构合金的开发,ACS Applied Energy …
2023年10月23日 · 本工作通过热处理和Ce掺杂成功合成了一种易活化、高性能的无V BCC型合金(Ti 40 Cr 50 Mo 10 Ce 1 )。 热处理将其脱氢能力显着提高至 2.5 wt%,这归因于斜率因子降低 (0.76–0.17),使其与 V 基 BCC 型合金相当。
