“…As a result, the low p -value (less than .05) shows that the model is significant at a 95% confidence level. 22 According to the ANOVA analysis, Fisher’s F-test results with a high F-value and low p -value indicated that the models were highly significant. The coefficient of determination (R 2 ) is analyzed as the ratio of the variability in the data described by the ANOVA analysis and defined in equation (6).…”

The present work studies the mechanical alloying, consolidation, evaluation, modeling, and optimization of the Al-TiC composites mixed at different milling times (MTs) of 6, 12, 24, and 48 h and reinforced with three TiC concentrations (3, 6, and 12 vol.%). The Al-TiC composites formed via the powder metallurgy method. The XRD of the mixed powder and the consolidated composites were investigated. Furthermore, density, wear, compressive strength, and hardness have been examined for the consolidated composites. Also, the worn surface of the wear-tested composites was studied utilizing SEM analysis. The response surface methodology (RSM) was involved to clarify the effects of mechanical alloying parameters of MTs and the TiC concentrations and their interaction towards achieving their optimum process factors to produce Al-TiC composites. The RSM results prove the applied factors’ importance in improving the consolidated composites’ properties. The optimization results show the optimum parameters to produce Al-TiC composites are 28.4 MTs and 12 vol.% TiC to produce Al-TiC composites with 304.4 ± 3 MPa compressive strength, 191.21 ± 2 HV hardness, 2.88 ± 0.008 g/cm3 density, and 9.7 ± 0.01 mg weight loss. The ANOVA analysis reveals that the suggested models can virtually expect the tested responses of density, hardness, compressive strength, and weight loss with a confidence level of over 90, 98, 95, and 95%, respectively.

Friction stir processing (FSP) with the overlapping method is the best approach for achieving bulk surface modification in metals and alloys. In the current study, a bulk-area processing region was created in aluminum alloys using FSP with pin overlapping. The grain size distribution and texture orientations have been examined using the electron backscattered diffraction technique. The findings revealed that the grain size distribution is uniform throughout the processed region, but the texture orientation is varied from one pass to other overlapping passes. Finally, it was identified from the results that the overlapping technique does not affect the grain size but affects the texture orientations and their intensities in each overlapping pass.

“…The maximum joint efficiency obtained was 80% [122]. Ahmed et al [58,[127][128][129][130] conducted several studies investigating the effect of the tool pin profile and traversal speed mechanical properties of aluminum alloys. Their The performance of the high-strength aluminum alloys was investigated after welding using BTFSW and compared with that welded by the conventional FSW (CFSW) [121][122][123][124][125][126].…”

The use of the friction stir welding (FSW) process as a relatively new solid-state welding technology in the aerospace industry has pushed forward several developments in different related aspects of this strategic industry. In terms of the FSW process itself, due to the geometric limitations involved in the conventional FSW process, many variants have been required over time to suit the different types of geometries and structures, which has resulted in the development of numerous variants such as refill friction stir spot welding (RFSSW), stationary shoulder friction stir welding (SSFSW), and bobbin tool friction stir welding (BTFSW). In terms of FSW machines, significant development has occurred in the new design and adaptation of the existing machining equipment through the use of their structures or the new and specially designed FSW heads. In terms of the most used materials in the aerospace industry, there has been development of new high strength-to-weight ratios such as the 3rd generation aluminum–lithium alloys that have become successfully weldable by FSW with fewer welding defects and a significant improvement in the weld quality and geometric accuracy. The purpose of this article is to summarize the state of knowledge regarding the application of the FSW process to join materials used in the aerospace industry and to identify gaps in the state of the art. This work describes the fundamental techniques and tools necessary to make soundly welded joints. Typical applications of FSW processes are surveyed, including friction stir spot welding, RFSSW, SSFSW, BTFSW, and underwater FSW. Conclusions and suggestions for future development are proposed.
