The aim of this work is to predict,for the first time,the high temperature flow stress dependency with the grain size and the underlaid deformation mechanism using two machine learning models,random forest(RF)and artificial neural network(ANN).With that purpose,a ZK30 magnesium alloy was friction stir processed(FSP)using three different severe conditions to obtain fine grain microstructures(with average grain sizes between 2 and 3μm)prone to extensive superplastic *** three friction stir processed samples clearly deformed by grain boundary sliding(GBS)deformation mechanism at high *** maximum elongations to failure,well over 400% at high strain rate of 10^(-2)s^(-1),were reached at 400℃ in the material with coarsest grain size of 2.8μm,and at 300℃ for the finest grain size of 2μ***,the superplastic response decreased at 350℃ and 400℃ due to thermal instabilities and grain coarsening,which makes it difficult to assess the operative deformation mechanism at such *** work highlights that the machine learning models considered,especially the ANN model with higher accuracy in predicting flow stress values,allow determining adequately the superplastic creep behavior including other possible grain size scenarios.

Relevance of liver fibrosis amongst diabetic patients with metabolic-dysfunction associated steatotic liver disease(MASLD)and knowledge gaps insulin resistance is paramount in the crosstalk between intrahepatic and extrahepatic pathophysiological mechanisms leading to MASLD(1),hence gaining special relevance in patients diagnosed with type 2 diabetes(T2D).MASLD is the term that was recently endorsed by an international multidisciplinary consensus panel to replace non-alcoholic fatty liver disease[as non-alcoholic steatohepatitis(NASH)was replaced by metabolic dysfunction-associated steatohepatitis(MASH)](2).
