The electric vehicle (EV) battery systems are complex assemblies of dissimilar materials in which cells connected using several thousand interconnect joints. Every single joint influences the functionality and efficiency whole system, making joining process crucial. Laser welding is considered a desirable choice for EV manufacturing due to its non-contact nature, high energy density, precise co...

Metallurgical accounting in the mineral processing industry transforms accumulated process data, including flow rates and assays, into a coherent information format. This is used to rapidly provide production reporting and key performance indications. Comprehensive and coherent data must be a component of any system expected to accomplish reconciliation in the mass-balancing process. Quality is...

Metallurgical activities have been undertaken in northern South America (NSA) for millennia. However, it is still unknown how far atmospheric emissions from these activities have been transported. Since the timing of metallurgical activities is currently estimated from scarce archaeological discoveries, the availability of reliable and continuous records to refine the timing of past metal depos...

Enlargement of quality requirements in metallurgical semi products used in cannon barrels production (forgings) has resulted in substantially increased number of defective products. The main issues are poor quality of plastic properties and yield point of processed materials. Careful analysis of forgings technology and adaptation of its constituent phases has not resulted in the quality enhance...

A fractured nutcracker was examined for determining the root cause/s for premature fracture/failure. This is one of the common tools used typically for cracking hard nuts. In this study, metallurgical failure analysis techniques namely, visual inspection, optical microscopy, SEM, and hardness tests were used in investigating the broken product. From the metallurgical analysis, it was determined...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The article presents the assumptions for construction of a transformation restructuring model which describes, in a complex way, the range of changes implemented in metallurgical enterprises in Poland in time of economical changes. The model was prepared on the basis of thorough rese...
