Metal Science and Heat Treatment Aims and scope

Conclusion

The life of alloy AK18 pistons, governed in particular by hardness, may be increased as a result of reducing the casting temperature, increasing the cooling rate after alloy solidification, correcting alloy composition within the grade limits, and using homogenizing before artificial aging.
