20.500.12556/ReVIS-13499 Sistematični pregled in primerjalna analiza nateznih lastnosti zlitine ti-6al-4v, izdelane z LPBF/SLM, na podlagi pregleda literature Systematic review and comparative analysis of tensile properties of ti-6al-4v alloy produced by LPBF/SLM based on a literature review Mehanske lastnosti kovinskih materialov, izdelanih s postopki selektivnega laserskega taljenja (LPBF/SLM), so v literaturi obsežno obravnavane, vendar so rezultati pogosto razpršeni in metodološko težko primerljivi. Na natezne lastnosti pomembno vplivajo procesni parametri, orientacija gradnje, mikrostruktura ter naknadne obdelave. Pri zlitini Ti-6Al-4V se pojavlja izrazita anizotropija ter kompromis med trdnostjo in duktilnostjo, povezan s slojevito izdelavo in martenzitno mikrostrukturo v stanju as-built. Namen magistrske naloge je s sistematičnim pregledom in primerjalno analizo literature prispevati k razumevanju razpršenosti mehanskih lastnosti ter k zanesljivejši interpretaciji mehanskega obnašanja Ti-6Al-4V, izdelanega z LPBF/SLM, v primerjavi s konvencionalnim materialom. Analiza kaže, da Ti-6Al-4V, izdelan z LPBF/SLM, v stanju as-built pogosto dosega večje vrednosti natezne trdnosti in meje tečenja, vendar ob večji razpršenosti rezultatov. Orientacija gradnje in mikrostruktura bistveno vplivata na duktilnost in lomno obnašanje, medtem ko toplotna in HIP-obdelava zmanjšujeta anizotropijo. Delo vzpostavlja analitični okvir za primerjalno vrednotenje rezultatov ter prispeva k jasnejšemu razumevanju potenciala in omejitev tehnologije LPBF/SLM. The mechanical properties of metallic materials produced by selective laser melting (LPBF/SLM) have been extensively investigated in the literature; however, the reported results are often scattered and methodologically difficult to compare. Tensile properties are significantly influenced by process parameters, build orientation, microstructure, and post-processing treatments. In the case of the Ti-6Al-4V alloy, pronounced anisotropy and a trade-off between strength and ductility are observed, associated with the layer-wise manufacturing process and the martensitic microstructure in the as-built condition. The aim of this master’s thesis is, through a systematic literature review and comparative analysis, to contribute to a better understanding of the variability in mechanical properties and to provide a more reliable interpretation of the mechanical behavior of LPBF/SLM-produced Ti-6Al-4V compared to conventionally manufactured material. The analysis indicates that LPBF/SLM-manufactured Ti-6Al-4V in the as-built condition often exhibits higher ultimate tensile strength and yield strength, albeit with greater variability. Build orientation and microstructure significantly affect ductility and fracture behavior, while heat treatment and hot isostatic pressing (HIP) reduce anisotropy. The thesis establishes an analytical framework for comparative evaluation of published results and contributes to a clearer understanding of the potential and limitations of LPBF/SLM technology. aditivna proizvodnja kovin selektivno lasersko taljenje (LPBF/SLM) mehanske lastnosti titanova zlitina (Ti-6Al-4V) metal additive manufacturing selective laser melting (LPBF/SLM) mechanical properties titanium alloy (Ti-6Al-4V) true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2026-04-09 13:39:04 2026-04-09 13:39:04 2026-04-10 03:21:37 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 6081 1241$$mag.naloga_blaz_josic_22237009_tp__27_2_2026.pdf 1241$$mag.naloga_blaz_josic_22237009_tp__27_2_2026.pdf 1 A1210D90DE03032386517B4BAC66F2C7 c61915bb88ddb09e623dcbe213a0e531d52f7e78f3c7d3b0ee1405db59d1cd22 b677aa80-3408-11f1-b941-001a4af901a5 https://revis.openscience.si/Dokument.php?lang=slv&id=16094 Univerza v Novem mestu - Fakulteta za strojništvo 0 0 0
