intergranular fracture an overview sciencedirect topics - intergranular fracture along prior austenite grain boundaries is the most common fracture mode for ihe hee and lme of high strength steels for normal metalloid impurity contents especially in steels tempered in the range where impurity segregation is prone to occur sem indicates that intergranular fracture surfaces are featureless in areas between ridges and isolated dimples fig 2 14, additive manufacturing 3d printing a review of - in fdm method a continuous filament of a thermoplastic polymer is used to 3d print layers of materials fig 1a the filament is heated at the nozzle to reach a semi liquid state and then extruded on the platform or on top of previously printed layers
