; ultrasonic shot peening treatment; ultrafine-grained microstructures; thermal conductivity 过去的十多年里, 包括纳米在内的各种具有超细组织的材料引起了材料研究者的广泛注意. 大量的研究结果表明, 这种材料由于具有超细的晶粒结构, 拥有大量的晶界或界面而显示出具有与常规大晶粒材料不同的性能[1-3]. 通过喷丸处理等强...晶组织的热导率与具有较大晶粒的基体相比有明显的降低, 其原因主要与细晶组织中导电电子浓度的降低, 晶格缺陷密度的增加及电子与声子在该类组织中的强烈散射有关. 关键词: 钛; 喷丸处理; 超细晶组织; 热导率 中图分类号: TG115.25 文献标识码: A Scanning thermal microscopy anaylsis of ultrafine-grained pure......
Heat Treatment of WC-Co Hardmetals and Transformation Temperature of Cobalt Phase赖和怡,杨金辉摘 要:<正> The Present work has found that the transverse rupture stren -gth of WC-Co hardmetals can be improved by queuching heat treatment. The increment of transverse rupture strength (4TRS) was dependent on the cobalt content of hardmetal. The higher......

, Guangzhou 510610, China) Abstract: BaPbO3 thin films were deposited on Al2O3 substrates by sol-gel spin-coating and rapid thermal annealing. The microstructure and phase of BaPbO3 thin films were... was investigated. The results show that heat treatment, including annealing temperature and time, causes notable change in molar ratio of Pb to Ba, resulting in the variations of sheet resistance......
