Special features of the formation of the microstructure and chemical heterogeneity in welded joints in alloys of the Al–Zn–Mg–Cu system alloyed with scandium

Special features of the formation of the microstructure and the development of chemical heterogeneity in the weld metal and heat-affected zone (HAZ) in arc welding of a complex alloyed alloy of the Al–Zn–Mg–Cu system are discussed. It is shown that the effect of welding heating results in melting of the phase components of the alloy in the HAZ with the formation of structures of the eutectic origin in the form of long interlayers at the boundaries of recrystallized grains, causing brittleness of the metal. Alloying the alloy with scandium reduces the intensity of the processes of recrystallization and the extent of liquation at the grain boundaries and also localizes the melting of the grains without the formation of thick eutectic interlayers.

Dynamic model of the formation of twinned martensite crystals: I. Control wave process and the removal of degeneracy in twin-boundary orientation

In terms of the concept of the control wave process, it is proposed to consider the formation of internally twinned martensite crystals as a result of a consistent action of quasi-longitudinal waves, which determine the orientation of the habit plane, and of shorter longitudinal waves, which make the major contribution to the control of the growth of the main component of the twin structure. A simple set of equations corresponding to the propagation of a threshold deformation that leads to the formation of platelike regions is given. It is shown that the removal of the degeneracy with respect to the orientations of the expected twin boundaries is due to the existence of feedbacks upon the initiation of the Bain-deformation mechanism. It is noted also that the twin structure can be formed through the excitation of short-wavelength cells in the inter-phase region at the stage of the martensite-crystal growth.     

Modification of the charge state and thicknesses of the polymer polyethylene interlayer in piezoceramics with various structures after their electric treatment

The variations of the charge state and the thicknesses of the polymer polyethylene interlayer in piezoceramics with different structures due to their electric treatment have been investigated. It is shown that the differences of the strength properties of the piezocompositions with various particle dimensions dependent on the field strength of the electric treatment are associated with the variation of the specific surface of the polymer interlayer. The fraction of the interfaces of the polymer matrix with the equal volume content of the piezoceramics increases with the decreasing of the dimensions of the piezoceramic particles. This leads to the increasing of the interphase interactions between the components of the composite.     

Nonadditive phenomena during polyaniline synthesis in the presence of mixtures of rigid-chain and flexible-chain polymer sulfoacids and their effect on properties of obtained interpolymer complexes

The matrix polymerization of aniline in the presence of mixtures of rigid-chain and flexible-chain polymer sulfoacids was investigated in the work. The optical, electric, and spectroelectrochemical properties of the forming interpolymer complexes of polyaniline, as well as their morphology, were studied. The dominating influence of rigid-chain polyacid on the process of formation of the interpolymer complexes of polyaniline even in the case of application of the mixture with the prevailing content of the flexible-chain polyacid was detected. The nonadditive dependence character of the viscosity of the mixtures of polyacid solutions, the duration of the induction period of aniline polymerization, and the optical absorbance and conductivity of the obtained complexes of polyaniline relative to polyacid ratios in the mixture was shown. The presence of the intermolecular interaction in the mixtures of polymer sulfoacids was shown via viscometry method, which may be the reason for the nonadditivity of the observed phenomena.     

含泄漏层的井下水力增压器增压特性研究

为了进一步提高水力喷砂射孔技术的射流压力,摆脱传统的地面增压方式因压力传输困难、能耗高等原因对深层地层岩石压裂难的困境,基于实际射孔工艺要求,设计了井下水力增压器。根据井下水力增压器的结构和工作原理,考虑活塞与活塞筒之间的泄漏层对增压效果的影响,建立了增压缸流体域模型,利用动网格技术对增压缸的增压特性进行数值模拟研究。研究结果表明:增压过程中,增压腔压力和流体出射速度均随时间先增大后逐渐呈现出高频周期性波动的规律;增压腔压力和流体出射速度随输入压力和低压腔与增压腔流体的有效作用面积比的增大而增大,且增压腔压力近似等于输入压力和有效作用面积比的乘积;泄漏层厚度对增压腔压力和流体出射速度的波动性影响很大。该研究结果为后期增压器结构设计和参数优选提供了参考。     

液相渗Si提高TiAl基合金的高温抗氧化性

使用液相Al—Si合金对TiAl基合金进行表面渗Si处理，可明显增强TiAl基合金的高温抗氧化性．经1273K，100h的恒温氧化后，不同的表面涂层使合金在40—100h之间的氧化速率降低了2个数量级，恒温氧化100h后的最终氧化皮脱落量也减少3个数量级．液相渗Si使TiAl基合金表面高温抗氧化性能得到大幅度改善，其根本原因是Si与TiAl中的元素Ti结合，降低了Ti的活度，相对增强了涂层中元素Al的活度，而且涂层中Al的绝对含量也得到明显提高，这些均抑制了高温氧化过程中TiO2的生成，涂层最外层形成了致密的Al2O3氧化膜．
