Figure 8
The graph illustrates the tensile strength, measured in megapascals, and the grain area, measured in square micrometres, at different temperature settings: As-built, 425 degrees Celsius, 650 degrees Celsius, 870 degrees Celsius, and 1150 degrees Celsius. The y-axis on the left represents tensile strength, ranging from zero to one thousand megapascal, while the right y-axis shows grain area, ranging from fifteen to forty square micrometres. Three series are plotted: XOY, represented by green squares; YOZ, represented by red circles; and X OZ, represented by blue triangles. The graph features vertical grey bars marking each temperature category, along with error bars indicating variability in data points. The data flows horizontally across different temperature settings, illustrating how tensile strength and grain area change with temperature.Comparison of the tensile strength and grain size of LB-PBF 316L SS samples in the as-built and heat-treated conditions
