Microstructure and Mechanical Properties of 30CrMnSiA Parts Repaired by Laser Cladding by HU Shuzeng, CHENG Donghai, CHAO Bingxuan, YING Junlong, WANG De, WANG Jun, WANG Wenqin

“…30CrMnSiA steel is extensively utilized in specialized tooling components， which frequently experience fatigue fractures and other damage mechanisms under cyclic stress during service.In this work，the laser cladding technology was adopted，and the microstructure and mechanical properties were analyzed based on process experiments.The optimal parameters were selected to perform laser repair on the damaged fork-shaped part of 30CrMnSiA， and its fatigue life was tested by a fatigue testing machine.Results showed that the microstructure within the repair layer was dense.The bonding interface between the repair layer and the base material was a typical metallurgical bonding，and no defects such as cracks occurred.The strength of the weld seam was higher than that of the base metal， and the tensile fracture was basically at the base metal.Besides，the specimen achieved a fatigue cycle count of 606 501，representing a 21.3%improvement in fatigue life compared to standard parts， meeting all operational requirements for specialized tooling components.…”

Cascade Bridge Interfacial Design for Stable and Sustainable Flexible Perovskite Solar Cells by Muhammad Fahim, Irum Firdous, Walid A. Daoud

“…Herein, we present a cascade bridge interlayer strategy of zeolitic imidazole framework‐8 (ZIF‐8) at the ZnO/perovskite interface. The ZIF‐8 interlayer uplifts the work function, creating a cascade pathway and bridges through nitrogen bonding with Pb2+ ions of perovskite, thereby facilitating electron transport and reducing interfacial charge recombination. …”

Effects of curing temperature and age on the mechanical properties and damage law of coal-based solid waste cemented backfill by Xiang He, Longqiang Wei, Ke Yang, Zhiqiang Wen, Lianfu Zhang, Yongqiang Hou

“…The results demonstrate that: (1) The increase of curing age and temperature would underpin the mechanical properties of CWCB, since the maximum strength reached 5.45 MPa, with the curing temperature of 42.5 °C and the curing age of 28 days. (2) A curing temperature of 50 °C inflicted physical and mechanical damage on the bonding interface of the backfill. As shown by the microscopic morphology comparison (20, 27, 35, and 42.5 °C), more irregular structures inside the specimens were resulted from excessive hydration reaction. …”
