Hussein Sayegh

Bachelor thesis titled: Influenza dei parametri di rinvenimento sulla microstruttura e sulla durezza di un acciaio da bonifica.

Description: This work focuses on the evolution of microstructure and hardness of a medium carbon quenched and tempered steel by varying tempering parameters. The aim is to investigate sustainable tempering parameters which may guarantee the same microstructure and hardness as the ones currently used in industrial production.

Nicola Mantovani

Bachelor thesis titled: Influenza del tempo di rinvenimento a 280 °C per un acciaio da cuscinetti 100CrMo7: effetto su microstruttura e durezza e confronto con il trattamento di austempering.

Description: This work analyzes the microstructural evolution and mechanical properties of the bearing steel EN 100CrMo7 subjected to different heat treatment cycles. In particular, austenitizing, quenching, and tempering at 280 °C with different holding times were carried out, and the results were compared with an austempered material. Metallographic analyses using optical microscopy and SEM, together with hardness tests, were used to correlate microstructural variations with the mechanical properties of the material. The results highlight how the parameters of heat treatment significantly influence the microstructure, hardness, and stability of tempered martensite.

Enrico Nicolini

Bachelor thesis titled: Proprietà a trazione e caratterizzazione microstrutturale di tre acciai temprati e rinvenuti per la produzione industriale di maglie sottocarro per macchine operatrici.

Description: The aim is to analyze the static properties and microstructure of three quenched and tempered steels used in the production of undercarriage track links for heavy-duty machinery. The results showed that the select heat treatment parameters and the chemical composition directly influenced the mechanical properties, thus it is possible to produce high-resistance components with a specifically designed performance.

Andrea Schincaglia

Bachelor thesis titled: Studio sperimentale e analitico per la valutazione dei migliori parametri di processo SLM per la stampa di una lega NiTi. 

Description: The thesys focuses on different combinations of SLM printing process parameters used for manufacturing NiTi samples. Density evalutation allowed finding the best combination of printing parameters in order to produce full dense samples. 

Gabriele Orsatti

Bachelor thesis titled: Analisi comparativa della resistenza ad usura erosiva di riporti duri saldati.

Description: The aim of the thesis is to evaluate the erosion resistance of a newly designed welding coating and to compare it with two commercial ones. To do this, erosion tests were performed in different conditions and profilometric analyses. The results showed that all three coatings have a comparable erosion index under the same conditions.

Bachelor thesis titled: Trattamenti termici degli acciai per cuscinetti: microstruttura, proprietà e analisi dilatometrica.

Description: The thesis analyzes heat treatments, particularly austempering, to achieve optimal mechanical properties in bearing steels. The microstructure transformation kinetics are studied using the dilatometric technique.

Sara Urbinati

Master's thesis titled: Studio tribologico di rivestimenti DLC e Hi-Crome depositati su una lega AlSi10Mg prodotta mediante L-PBF.

Description: This thesis investigates the tribological behavior of DLC and Hi-Crome coatings on L-PBF AlSi10Mg alloy. Using pin-on-disc testing and SEM analysis, the influence of heat treatments and surface finishing on friction and wear properties was evaluated. Results show optimal performance for as-built DLC, while the Hi-Crome system provides superior substrate protection due to the Ni-P interlayer.

Ottavia Vezzani

Master's thesis titled: Finite Element Simulation And Experimental Validation Of Surface Densification In Powder Metallurgy Steels By Rolling Using The Gurson–Tvergaard–Needleman Model.

Description: The thesis investigates the plastic behavior of porous sintered steels, with a focus on surface densification through rolling. A calibration procedure for the Gurson–Tvergaard–Needleman (GTN) model in Abaqus is proposed and validated, demonstrating good agreement between simulations and experimental tests and highlighting the importance of properly defining the hardening curve for the model’s predictive accuracy.

Lorenzo Antonioli

Master's thesis titled: Ottimizzazione dei parametri di solubilizzazione nel trattamento termico T6 di una lega di alluminio da fonderia AlSi7Cu0.5Mg0.3: caratterizzazione microstrutturale e valutazione delle proprietà statiche.

Description: Evaluation of the effectiveness of new solubilization parameters that are more economically sustainable and have a lower environmental impact in the T6 heat treatment of AlSi7Cu0.5Mg0.3 secondary alloy castings. The proposed solubilization parameters have been studied in terms of their ability to ensure tensile strength and hardness properties comparable to those achieved with the current heat treatment parameters adopted within the industrial production.

Elena Collini

Master's thesis titled: Analisi ed ottimizzazione della produzione di un componente automotive prodotto per LPDC.

Description: The thesis was developed to examine how process parameters a low-pressure die cast (LPDC) automotive component. Different parameters have been set to distinguish two production processes analyzed both in simulation and comparing the mechanical characteristics with samples taken from tests conducted on machines. The study has made it possible to improve product quality, both in terms of reduction of casting defects and in terms of mechanical characteristics.
