Summary: Superlight Mg-10Li-3Al-3Zn (LA103Z) alloy cabins were fabricated using multi-directionally forging, die forging, and annealing treatment. The cabins showed a combination of different phases including alpha-Mg, beta-Li, AlLi, MgLi2Al, and Mg17Al12. The die-forged cabin at 260 degrees C and 6 mm/s exhibited superior strength due to the sufficient dissolution of AlLi phases, fine grain size, and reasonable distribution of MgLi2Al particles. Further annealing at 245 degrees C for 3 h resulted in the optimal mechanical properties with high tensile strength and elongation. This study provides a feasible method for producing high-performance large-scale Mg-Li components.

Summary: A Mg-1.0Mn-1.0Zn (wt.%) alloy with ultra-high strength was prepared by extrusion at 438 K and forging at 453 K. The alloy achieved high tensile yield strength of 373 MPa and ultimate tensile strength of 417 MPa with only 2 wt% low-cost alloying element additions, due to the combination of ultrafine dynamic recrystallized grains, high-density dislocations, nanoscale precipitates, and strong texture. It is believed that this low-temperature deformation method can be widely applied in industrial fields to fabricate other low-alloyed Mg alloys with ultra-high strength.

Summary: Investigation into non-equiatomic high-entropy alloys has been increasing due to the need to understand the role of entropy stabilization in forming single-phase solid solutions. These alloys retain the excellent mechanical properties of their equiatomic counterparts and even exhibit improved electrical, thermal, and magnetic properties. A new method for developing high-entropy alloys is proposed, where controlled processing conditions determine the most stable composition. This method is demonstrated by cooling an equiatomic CrMnFeCoNiCu alloy, resulting in an alloy with large Cr-rich precipitates and an almost Cr-free matrix, leading to the discovery of a unique non-equiatomic alloy, Mn17Fe21Co24Ni24Cu14.

Summary: This study investigated the bioleaching behavior of Cu and Co from non-ferrous residues using iron-oxidizing bacteria (IOB) and sulfur-oxidizing bacteria (SOB). The results showed that IOB had a better performance on extracting Cu and Co, especially for Cu. Under the optimal ratio of the initial number of IOB and SOB, 77.7% and 79.8% of Cu and Co were extracted, indicating a promising application prospect for cleaner resource recycling.

Summary: In this study, AZ31 magnesium alloy rolled sheets with a thickness of 0.8 mm were prepared using particle micro-forging and cold spraying equipment. The plasticity of the sheets was improved by annealing them at 250 degrees C for various durations. The investigation revealed that particle micro-forging induced the formation of twins and led to grain refinement, while the annealing treatment caused static recrystallization and the formation of equiaxed grains, weakening the basal texture of the sheet. The annealing treatment also improved the plasticity and anisotropy of the sheet.

Summary: This study investigates the effects of dwell period and microstructural conditions on dwell sensitivity in titanium components of gas turbine engines. The results show that dwell time and crystal orientation distribution have significant influences on dwell sensitivity, with a saturation point reached at 120 seconds. Extending the dwell time further increases dwell sensitivity in locations with low sensitivity.

Summary: This study investigated the mechanical properties and texture evolution of Cu-xZn alloys processed by multi-directional forging (MDF) up to 6 passes at ambient temperature. It was found that the enhancement of mechanical properties can be attributed to grain refinement, with the presence of Brass and Goss texture components related to the increase in Zn content.

Summary: This study proposes a method of accelerating phase formation of magnetic refrigerants through cold compression plastic deformation at room temperature. The grain structure, phase composition, and magneto-thermal effects of LaFe(13.1)Co(0.7)Si(1.4) alloy were systematically studied. The results show that pre-compressed samples have increased proportion of magnetothermal phase and exhibit significant magnetic entropy changes, making them attractive candidates for room temperature and high-temperature magnetic refrigeration applications.

Summary: The study evaluated heavy metal pollution in abandoned non-ferrous metal tailings using various assessment methods, identifying Mo, Cd, Pb, Sr, and Mn as high-risk elements, while Cu, Ni, Cr, and Zn are low risk. Results indicated that the evaluation of Mo, Mn, and Sr is more accurate, and the release of Pb and Cd is influenced by the pH of the tailings. The most significant finding was the proposal of a comprehensive integration result of pollution risk levels based on multiple assessment methods.

Summary: A dilute Mg-Mn-Ca-Ce alloy fabricated by bidirectional forging exhibits variable mechanical properties from the edge to the center due to gradient microstructure. The optimized proportion of bimodal grains with low-density dislocation was developed in the center position as a result of higher cumulative strain and temperature, contributing to higher tensile strength and elongation compared with other positions.

Summary: This study proposed a new approach of hot forging deformation to solve the difficulty in forming magnetocaloric phase in La-Fe-Si alloys, revealing that the novel microstructure formed during forging played a key role in promoting phase formation and enhancing magnetic entropy change. Prominent magnetic entropy change was achieved through annealing and hydrogenation, while maintaining sample integrity.
