Relaxation process and phase transition of lanthanide liquid crystalline complexes by photoacoustic spectroscopy李俊嘉,杨跃涛,刘晓峻,张淑仪,张仲宁摘 要:Lanthanide-containing liquid crystals exhibiting smectic A phase close to room temperature were obtained. Photoacoustic (PA) spectroscopy was used to study the spectral properties and phase transitions of liquid......
is selectively oxidized, while WC remains stable due to the existence of carbon containing liquid organic cutting medium. Key words: cemented carbide; dual phase structure; functionally graded material... the preparation of low carbon containing precursor with WC+γ+η unconventional structure by vacuum liquid phase sintering, followed by carburizing treatment. The basic composition of the alloy is WC-6%Co (mass......
. The β-Al3Mg2 phase dissolves under the condition of testing temperatures higher than 523 K, which causes solid-solution quantity of Mg atoms to increase. Therefore, the "abnormal transient creep" may be related to the difference of solid solution strengthening caused by phase change during the creep tests. Key words: Al-5356 alloy; transient creep; phase change; low strain rate 1 Introduction......
