In the experiments, the reactive material fragments impacted 3.76-, 5.02-, 7.58-, and 9.69-mm-thick steel plates at velocities ranging from 400 m/s to 1000 m/s. The findings indicate that violent deflagration occurred when energetic fragments penetrated the steel target, resulting in noticeable firelight both in front of and behind the target. The damage patterns observed in the 3.76-mm steel plate exhibited distinct petal shapes, while those observed in the 5.02-, 7.58-, and 9.69-mm-thick steel plates displayed characteristic perforations. The ballistic limit velocities, ranging from 431.2 to 838.5 m/s, were determined based on experimental findings. Further, the present study presents a semi-empirical model for predicting the ballistic limit velocities of Nb17Zr33Ti17W33 energetic fragments penetrating a steel target, and the calculated theoretical values demonstrate exceptional agreement with the experimental results, thereby substantiating the reliability of the proposed model. The experimental results demonstrate that the perforation diameter of Nb17Zr33Ti17W33 reactive fragments on the steel plate exceeds that of DT300 steel fragments by 10–15%. A theoretical analysis has been conducted to compare the penetration capability of Nb17Zr33Ti17W33 fragments with that of conventional steel fragments, and it has been found that there is a critical threshold: the superior penetration ability of energetic fragments gradually becomes prominent only beyond the critical value.</div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"77 1","pages":"225 - 238"},"PeriodicalIF":2.1,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Welding parameters and tool shoulder designs influence material flow dynamics and stirring during the FSSW process. The current study uses a newly manufactured pinless tool to focus on the FSSW of 3-mm-thick AA7075-T6 aluminum sheets, which were joined using a pinless tool with a concave shape of three grooves for improved flow characteristics. The experiments explore the impact of welding parameters on the weld quality. Tensile tests, macroscopic examination, fracture surface analysis, and microhardness tests were performed. The geometric characteristics of hook shape and effective weld width substantially affected the tensile shear load (TSL). Tensile test findings and changes in effective weld width with welding parameters reveal that low rotational speed, high penetration depth, and dwell time parameters can result in a high TSL. Microhardness profiles reveal that the stir zone (SZ) exhibits the highest hardness values, reaching 27% above the base material hardness. The heat-affected zone (HAZ) shows the lowest hardness values.

However, this method results in the separated blackmass with high levels of Al and Cu impurities, making it unsuitable for direct regeneration (a promising post-treatment technique for electrode blackmass). Here, a process optimization scheme with multiple pulverizing and sieving was proposed to reduce the Al and Cu contents in the separated cathode and anode blackmass to 0.046% and 0.359%, respectively, well below the threshold for direct regeneration. Additionally, the recovery rate of cathode and anode blackmass was also achieved, reaching 95.392% and 98.674%, respectively. Specifically, the mechanisms affecting the separation efficiency and the synergistic effects of various factors (including mesh size, pulverizer load, pulverizing time, and process steps) in electrode blackmass separation during pulverizing and screening processes are deeply explored.
