M&M-Lab

The M&M-Lab is part of the network of laboratories of the research group on Materials and Innovative Technology (SMATIgroup), which work in the scientific Area of Manufacturing Systems and Technologies. The network includes the laboratories of Advanced Forming & Manufacturing, Physical Simulation of Manufacturing processes, Optimization of Manufacturing Processes by Numerical Simulations, and Thermo-Physical Characterization of Post-Formats Polymers. The laboratories of the network are locate di the DMMM, Viale Japigia 182 – Bari - Italy
Aim
The M&M-Lab performs teaching, research and service activities on the analysis of metals and alloys microstructure in relation to the physical and technological process involved in the production of an industrial part. Using Metallography for the specimens preparation (sectioning, mounting, course grinding, fine grinding, mechanical and electrochemical polishing, chemical and electrochemical etching) and Optical Microscopy for the microstructure evaluation, the procedures implemented in the lab allow to determine whether an alloy was correctly manufactured, observing the amount and morphology of microstructures or defects such as voids, cracks or impurities.
Skills
Supporting the SMATIgroup research activities, in the M&M-Lab have been developed skills on the metallographic analysis of steels and light alloys (titanium, magnesium and titanium), when processed with different manufacturing processes, such as heat treatments, laser beam welding, laser beam hardening, laser-MIG welding, MIG and Cold Metal Transfer welding, explosion welding of dissimilar aluminium-steel, superplastic forming, sheet metal forming (in cold, warm and hot condition).
Current research activity
Currently, the M&M-Lab is involved in research activities financed by the Ministry of Education and by private industry, aimed to the aimed to the (i) experimental validation an the process analysis of new assembly technologies for the lightening of vehicle structures (Single-Side Resistance Spot welding, Friction Stir Spot Welding, Friction Element Welding, fiber laser welding). (ii) hot stamping of advanced high strength steel
