| description | The present paper aims the investigation on the influence of Fe based amorphous on strength of aluminum alloy (Al-12Si), and the thermal deformation behavior of new Al-12Si/Fe base amorphous composites. On this foundation, a heat flow stress model of the sample was proposed by a Zener-Hollomon parameter and microstructural studies were carried out on Al-12Si/Fe base amorphous composite by many means. Microstructural study reveals dynamic recovery and dynamic recrystallization of Al-12Si/Fe base amorphous composite at thermal compression text. In addition, the deformation activation energy of Al-12Si/Fe-based amorphous composites is as high as 211.29 kJ mol ^−1 , compared with Al-12Si alloy (170.51 kJ mol ^−1 ). Importantly, the flow stress equation of the new composite is $\dot{\varepsilon }$ = 4.42×1014 [sinh(0.0166 σ) ]6.13 exp(−211290/ RT ), and the linear regression coefficient is 0.99. This study constitutes a significant advance in strengthening the Al-12Si engine piston and controlling the thermal deformation behavior and opens new directions for the development of piston material. |
