| 1 | MICROSTRUCTURAL STABILITY OF LAMELLAR TiAl BASED ALLOYS AT HIGH TEMPERATURES显示文摘The microstructural stability of lamellar TiAl base alloys at high temperatures was studied by conventional and high resolution transmission electron microscopy. The influence of substructures on the thermal stability of lamellar structure was emphasized. These substructures produced by thermal mechanical treatments include the interfacial dislocations and ledges, the subgrain boundaries, the impinged T(Q) twins and misorientated lamellar interfaces. The microstructural change of three kinds of lamellar TiAl base alloys containing differents type and densities of substructures were compared during exposure at 800~1 000 ℃. It was found that the existence of such substructures could accelerate the degeneration of lamellar structure, leading to the rapid necking and break up of α 2 plates, the coarsening of γ plates, and the formation of new γ grains. As a result, the lamellar structure with substructures started to degenerate after thermal exposure at 800℃ for 4.5 h. While only slight coarsening was observed at the colony boundaries in the lamellar structure without substructures even after exposure at 900 ℃ for 7 d. | G. L. Chen *, L. C. Zhang *# , and W. J.

| 2 | ANALYSIS OF FLUID FIELD OF LIQUID METAL IN ELECTROMAGNETIC CENTRIFUGAL CASTING显示文摘Navier-Stokes equation and Lorentz force equation are used to calculate the fluid field of liquid metal of electromagnetic centrifugal casting(EMCC) in this paper.A field equationis given,which shows the azimuthal velocity closely relates to electrical conductivity,mag-netic density,viscosity of liquid metal and radius of casting.The results show that the sta-tionary magentic field can effectively restrain the fluid flow and the relative velocity be-tween liquid metal and casting mould and the velocity gradient at solid/liquid interface in-creases with rising magnetic density,which has a great effect on the solidification of liquidmetal and crystal growth characteristies. | JIAO Yuning, LIU Qingmin, YANG Yuangsheng, HU Zhuangqi,Institute of Meta] Research, Chinese Academy of Sciences, Shenyang, ChinaGAO Yunyan, JIA Guanglin, ZHANG Guozhi, QIAO YuanjunNortheast University, Shenyang, China Manuscript received 12 May, 1994 | 1994 | Acta Metallurgica Sinica(English Letters)1994，7，2： | 2 |

| 7 | Female competition for availability of males in insects:the Nezara viridula(Linnaeus,1758)model显示文摘Multimodal communication in solitary stinkbugs enables them to meet,mate and copulate.Many plant-dwelling species exchange information during the calling phase of mating behavior using substrate-borne vibratory signals.A female-biased gender ratio induces rivalry and competition for a sexual partner.Female competition for males,first described among Heteroptera in three stinkbug species,revealed species specific differences and opened the question of plasticity in individually emitted temporal and frequency signal characteristics during calling and rival alternation.To address this question and gain an insight into the mechanisms underlying stinkbug female rivalry,we compared the characteristics of alternated signals in the southern green stinkbug Nezara viridula(Linnaeus,1758)(Hemiptera:Pentatomidae).Compared to male rivalry,female rivalry is more complex,lasts longer and runs through successive phases by a combination of different song types.The male pheromone triggers alternation between females,producing song pulses that occasionally overlap each other.One female initiates the rivalry by changing individual pulses into pulse trains of three different types.The competing female alternates with pulses of changed temporal characteristics at lower levels of rivalry and by varying the frequency characteristics of pulse trains at higher levels.During female rivalry,the male either stops responding or occasionally emits calling and courtship signals in response to the female that has produced signals of steady temporal characteristics.Female rivalry shows complex and species specific patterns of information exchange at different levels with a broad-range variation of temporal and frequency characteristics of,until now,unidentified vibratory emissions. | Andrej Cokl Alenka Zunic Kosi Raul Alberto Laumann Meta Virant-Doberlet | 2020 | Insect Science2020，27，4： | 1 |
