Morphology and Formation of Chrysanthemum-like Pearlite in 100Mn13 Steel During Aging Treatment
The morphology and microstructure of pearlite formed in 100Mn13 high-carbon high-manganese steel aged, respectively, at 525 °C and 650 °C after 1050 °C water toughening treatment were observed and analyzed by a scanning electron microscope (SEM) and transmission electron microscope (TEM). The result...

| description | The morphology and microstructure of pearlite formed in 100Mn13 high-carbon high-manganese steel aged, respectively, at 525 °C and 650 °C after 1050 °C water toughening treatment were observed and analyzed by a scanning electron microscope (SEM) and transmission electron microscope (TEM). The results show that some pearlite colonies are chrysanthemum-like and are composed of M<sub>7</sub>C<sub>3</sub> lamellae and ferrite lamellae, maintaining an orientation relationship (OR) of (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mover accent="true"><mn>3</mn><mo stretchy="true">¯</mo></mover></mrow></semantics></math></inline-formula><inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mn>3</mn></semantics></math></inline-formula><inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>12</mn></mrow></semantics></math></inline-formula>)<sub>M7C3</sub>‖(<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>0</mn><mo> </mo><mover accent="true"><mn>2</mn><mo stretchy="true">¯</mo></mover><mo> </mo><mn>4</mn></mrow></semantics></math></inline-formula>)<sub>α</sub>, [<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>4</mn><mo> </mo><mn>0</mn><mo> </mo><mn>1</mn></mrow></semantics></math></inline-formula>]<sub>M7C3</sub>‖[<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>5</mn><mo> </mo><mn>2</mn><mo> </mo><mn>1</mn></mrow></semantics></math></inline-formula>]<sub>α</sub>.
