METHOD FOR RELIEVING RESIDUAL STRESS IN CAST-IN-PLACE LINERS OF HPDC ENGINE BLOCKS

A method for relieving residual stress in cast-in-place liners of high pressure die cast (HPDC) engine blocks to prevent cracking in the liners during the machining process. The method includes locally heating up the liners and the surrounding engine block material through rapid induction heating an...

Zusammenfassung:	A method for relieving residual stress in cast-in-place liners of high pressure die cast (HPDC) engine blocks to prevent cracking in the liners during the machining process. The method includes locally heating up the liners and the surrounding engine block material through rapid induction heating and then cooling down the liners and surrounding engine block material with still ambient air to a predetermined temperature after the residual stress has been reduced to a desired threshold.
