The co-effects of grain size gradient, slip system compatibility, subgrain formation, and multiple slip system activation on back stress generation are clarified. The results show that the dislocation accumulates and back stress generates around the grain boundary owing to the inhomogeneous deformation behavior between large and small grains. For back stress generation, grain size gradient is the initial requirement and the subgrain formation within large grains will not suppress the back stress generation. Besides, low slip system compatibility of the adjacent large/small grains must be strictly satisfied for back stress generation. Otherwise, the grain boundary may provide limited hindering effect on dislocation motion, leading to the easy slip transfer. As a result, the dislocation density gradient at two sides of the grain boundary is diminished, and the back stress becomes not significant. In addition, the multiple slip system activation within one specific large grain may suppress back stress generation, as it promotes the motion and annihilation of dislocations.</div></div>","PeriodicalId":54332,"journal":{"name":"Journal of Materials Research and Technology-Jmr&t","volume":"38 ","pages":"Pages 879-892"},"PeriodicalIF":6.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144771731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their widespread adoption is hindered by intrinsic challenges such as poor fiber-matrix interfacial bonding, hydrophilicity, and variability in fiber quality. This review comprehensively evaluates recent advancements in functionalization strategies, including chemical, physical, biological, and hybrid approaches, to improve the structural and environmental performance of PFRCs. The review emphasizes how these modifications influence mechanical strength, thermal stability, and moisture resistance. It also assesses their environmental compatibility, scalability, and industrial relevance. Currently, chemical treatments are the most effective for enhancing interfacial adhesion, yet often involve trade-offs in toxicity and sustainability. In contrast, biological and hybrid methods are gaining prominence for offering multifunctionality with reduced ecological impact. The review further highlights the need for regionally adaptable, low-cost, and circular functionalization techniques to meet industrial processing demands. Future research directions are proposed to integrate green functionalization methods into scalable manufacturing platforms, enabling PFRCs to serve as viable materials across high-performance sectors such as construction, automotive, biomedical, and packaging. By addressing these critical gaps, this review offers a strategic framework for advancing PFRCs as next-generation bio-based composites aligned with global sustainability goals.</div></div>","PeriodicalId":54332,"journal":{"name":"Journal of Materials Research and Technology-Jmr&t","volume":"38 ","pages":"Pages 1083-1102"},"PeriodicalIF":6.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144771783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings revealed that the specimen subjected to a 30.0 % pre-strain exhibited the highest corrosion resistance. This improvement was attributed to the synergistic effect of a refined microstructure—marked by an increased fraction of low-angle grain boundaries (LAGBs) and low Σ coincidence site lattice (ΣCSL) boundaries—and the formation of compact passive films, as evidenced by elevated Cr₂O₃/Cr(OH)₃ and O²⁻/OH⁻ ratios. In contrast, when the pre-strain reached 37.5 %, the corrosion performance deteriorated. Although the quantity of LAGBs and ΣCSL boundaries continued to rise, their positive influence was overshadowed by the formation of excessive α′-martensite, high density of dislocations, and defects within the passive films.

A thermo-metallurgical finite element model (FEM) was employed to analyze the thermal history, phase distribution, and residual stress variation in double-sided butt-welded ST-37 samples during the GMAW process.

Using a Taguchi experimental design, the effects of key processing parameters—nozzle temperature, layer thickness, number of outer walls, and post-heat treatment duration—on shear strength were systematically analyzed. Experimental results indicated that PA6-CF15 specimens exhibited higher maximum shear loads compared to neat PA6, although they demonstrated more brittle behavior and lower ductility, primarily due to insufficient fiber bridging in the Z-direction. The optimal parameters for maximizing shear strength were identified as a nozzle temperature of 260 °C, a layer thickness of 0.15 mm, two outer walls, and 80 min of post-heat treatment. Finite Element Analysis (FEA) corroborated experimental findings by revealing stress concentrations near shear notch regions and confirming that optimized parameters enhance interlayer cohesion. Furthermore, comprehensive surface roughness measurements and Scanning Electron Microscopy (SEM) analyses provided detailed insights into damage progression. Higher nozzle temperatures and thinner layers resulted in smoother surfaces and denser structures, which correlated with improved shear strength. SEM images revealed complex failure mechanisms including fiber-matrix debonding, fiber pullout, matrix cracking, and fiber breakage, with evidence of matrix smearing and ductile drawing. The finite element simulations predicted a maximum shear stress of 151.6 MPa and an average shear stress of 23.4 MPa under optimized conditions, aligning well with experimental observations. Among the examined parameters, layer thickness had the most pronounced influence on shear strength, followed by wall line count and heat treatment duration, while nozzle temperature exhibited a comparatively moderate effect.
