LSP without coating (LSPwC) has emerged as an attractive alternative that eliminates the need for protective coatings, simplifies processing steps, and reduces costs. However, the comparative advantages of LSPwC and conventional mechanical shot peening (SP) for titanium alloy surface enhancement remain unclear. In this study, the effects of SP and LSPwC on the residual stress distribution and deformation characteristics of Ti60 alloy are systematically compared. The results reveal that although SP generates a higher maximum compressive residual stress (−549 MPa) than LSPwC (−392 MPa), it produces a shallower compressive layer (280 μm vs. 370 μm). Analysis of the full-width at half maximum (FWHM) indicates distinct stress profiles: SP induces the most severe elastoplastic deformation at ∼50 μm depth, accompanied by a non-monotonic stress distribution, whereas LSPwC primarily affects the outermost surface. Moreover, SP provides stronger surface strengthening within ∼150 μm depth, while LSPwC—due to its lower energy input—achieves a deeper compressive residual stress layer. These findings enhance the understanding of SP and LSPwC mechanisms, providing critical insights for optimizing surface processes in industrial applications.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"189 ","pages":"Article 113100"},"PeriodicalIF":4.6,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A fundamental understanding of the process-interfacial property relationships is crucial for process optimization and performance control of LPBF-formed dissimilar material parts. Different from the majority literature that focuses on the formation of pores and brittle microstructures at the interface zone, this work uniquely explores the thermal features and interfacial stresses (those are regarded as the main reasons of process failures and fractures) in LPBF forming dissimilar material parts and the influence of forming height on the residual stress distributions. A coupled thermo-mechanical model using the finite element method was proposed to simulate the residual stress distributions at the interfacial zone for several designed part parameters. A combined experimental and numerical study was conducted to record the interfacial stress field of different forming heights to reveal the mechanisms of stress evolution with heat accumulation. The numerical results show that the interfacial stress increased by at least 26 % as the forming height of AlSi10Mg doubled, while it decreased to 50 % with stress relieving treatment in Ti6Al4V. The presence of initial stress and heat accumulation both lead to uneven deformation at the interface zone, thus resulting in larger residual stresses.</div></div>","PeriodicalId":19511,"journal":{"name":"Optics and Laser Technology","volume":"189 ","pages":"Article 113035"},"PeriodicalIF":4.6,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143899258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Near-surface residual stress was non-destructively tested through an innovative application of the Short Wavelength Characteristic X-ray Diffraction technique (SWXRD). Compressive residual stress predominated within the 2.0 mm thick after LSP, reaching maximum values of −95.9 MPa (15 J) and −103.6 MPa (30 J) at a depth of 0.6 mm, exhibiting a spoon-shaped profile. Surface hardness increased by 24 % (15 J:136 HV) and 35 % (30 J:149 HV) compared to the untreated sample (114 HV), with an affected depth exceeding 2.0 mm. Dislocation density analysis revealed a depth-dependent gradient across specimen cross-sections, with sample S1 (15 J) and S2 (30 J) showing 21 % and 8 % increases, respectively, in near-surface regions compared to untreated S0. Higher LSP energy (30 J) promoted sub-grain formation, leading to a reduction in dislocation density beyond a depth of 0.6 mm. The proportion of low-angle grain boundaries near the 0.36 mm surface exceeds 65 % in both LSP-treated specimens versus approximately 60 % in untreated S0. Surface topography analysis revealed a 2.65-fold increase in Ra value for the S2 (77 nm) compared to the S1 (29 nm).
