采用激光-电阻复合焊接LF6铝合金,对焊接特性进行研究。通过激光和电阻热源相互作用,接头熔深和焊缝面积显著增加,实现了在小功率激光条件下铝合金熔透焊接,提高了焊接生产率,降低了焊接成本。与激光焊接相比,激光-电阻复合焊接铝合金接头中的气孔数量大幅下降。激光-电阻复合焊接的焊缝区的强化β(Al8Mg5)相弥散分布,呈铸态组织特征,热影响区(HAZ)的强化β相聚集长大。接头在焊缝断裂,呈韧性剪切断裂,平均抗拉强度可达292 MPa,约为母材的83.4%。

Intelligent coding metasurface holograms by physics-assisted unsupervised generative adversarial net
Intelligent coding metasurface is a kind of information-carrying metasurface that can manipulate electromagnetic waves and associate digital information simultaneously in a smart way. One of its widely explored applications is to develop advanced schem

A quasi-continuous-wave intracavity frequency-doubled Nd:YAG laser which operates at 660 nm is studied. By using a flat-flat laser cavity, 2 Kr-lamps, KTP crystal and an acousto-optically Q-switch, 2-W output power at 660 nm is obtained. The relationship
We present two novel 1*N dynamic optical couplers that are based on Dammann gratings to achieve dynamic optical coupled technology. One is presented by employing a specially designed Dammann grating that consists of the Dammann-grating area and the blank
We propose a general correction method for the efficiency measurement of optical components in the 45–110 nm range to eliminate the contamination of higher-order harmonics at beamline U27 of the Hefei Light Source (HLS). The influence of harmonics can be
