Welding is widely used in the manufacture of steel products. Metallurgical processes during welding produce residual stresses different zones welded parts. stresses, particularly tensile can significantly impact reliability and integrity components. Our recent works report effect stress redistribution a relatively short, up to two weeks, period after procedure. The hypothesis that observed relaxation phenomenon associated microstructure evolution occur material end procedure was proposed. To...
A study of the migration grain boundary misorientation and its relationship with residual stresses through time immediately after completion a thermomechanical simulation has been carried out. After physically simulating an intercritically overheated welding heat affected zone, variation contours was observed electron backscatter diffraction (EBSD) technique likewise RAYSTRESS equipment. It that in ASTM DH36 steel modified simulation, which corresponds to measured stress along first week...
The methodologies and deterministic inventory models, as well resource optimization within small medium-sized enterprises (SMEs), constitute valuable tools that address crucial aspects such order planning classification. These provide strategic approaches to enhance operational efficiency decision-making the scope of supply chain management. aim this study was employ Silver Meal (SM) ABC in a meat SME achieve balance between product availability, cost reduction, demand satisfaction. Using...
ResumoProcessos metalúrgicos durante soldagem provocam tensões residuais em peças soldadas.Recentemente foi observado um efeito de redistribuição das num período até duas semanas após o termino do processo soldagem.Existe hipótese nossa que esta está associada a mudança na microestrutura ocorre no material soldagem.Para provar hipótese, uma simulação física dos ciclos térmicos realizada utilizando termomecânica (GLEEBLE
