The volumetric energy density (VED) is a crucial factor in evaluating consolidation with unfused or unmelted LPBF particles and is affected by the laser power, scan speed, scan spacing, and layer thickness. This study investigated the impact of VED ranging from 74.67 J/mm³ to 178.57 J/mm³ on the morphology and mechanical properties of the SS 310 samples, specifically their hardness and tensile strength. The top residual stresses (TRS) were greater than those on the lateral surfaces (LRS). The results also revealed that VED significantly influences recrystallisation, reducing VED by decreasing the dislocation density. High VED reduces porosity and defects, increasing part of the density. As the VED increased, the as-built samples exhibited an austenite phase and larger columnar grains. The hardness of the samples ranges from 280.4±3.81 (S1) to 300.8±4.34 HV (S24), with an increase due to reduced void formation, whereas pores allow deeper penetration, resulting in lower HV values. The ultimate tensile strength (UTS) ranged from 768.55±5.34 MPa (S25) to 854.57±2.73 MPa (S3), whereas the tensile ductility ranged from 4.72% to 12.08%. The difference was 10% between the highest and lowest UTS values. The decrease in VED resulted in increased defects, which affected elongation. Fractography revealed defects causing premature failure of the SS310 samples, with internal defects influencing crack propagation and decreasing mechanical properties. The most suitable VED range for achieving a maximum hardness of 300.8±4.34 HV (S24) and the highest UTS of 854.57±2.73 MPa (S3) with 7.4% elongation were 125 J/mm³ and 91.26 J/mm³, respectively.</div></div>","PeriodicalId":18265,"journal":{"name":"Materials Research Bulletin","volume":"192 ","pages":"Article 113592"},"PeriodicalIF":5.3,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CPA films were exposed to in-situ gamma irradiation at dosages ranging from 0 to 30 KGy to optimize their physicochemical and microstructural features. The effect of gamma irradiation on the structural and morphological features of the composite, as well as its influence on the charge transfer resistance and photovoltaic performance of DSSCs, was extensively studied. The SEM micrographs reveal changes in surface morphology and porosity as the irradiation dose increases. The surface features of the irradiated CE hybrids also gradually enhanced as the gamma dosage increased, reaching the desired levels at 25 KGy (average roughness (Ra) = 7.87 µm, apparent porosity = 79.4 %, and bulk density = 1.68 g/cm³). The interaction of high-energy gamma photons created promising conditions for charge separation, minimizing recombination and enhancing charge carrier mobility within the CPA composites. These improvements in mobility and the reduction of resistive losses contributed to an extended cell lifespan and more efficient charge transfer. Interestingly, surface modification at 25 KGy resulted in an optimized efficiency of 8.25 % and a short-circuit photocurrent density (J_sc) of 18.056 mA/cm², reflecting a 37.76 % increase compared to the untreated sample. This enhancement in photovoltaic performance is attributed to the generation of oxygen-enriched free radicals within the CPA structure, which facilitated the formation of continuous pathways for efficient electron transport.
