Abstract: A method and system for processing an engine block that includes a cylinder liner. The engine block having a first material with different coefficient of thermal expansion than a second material forming the cylinder liner. The method includes providing an insulating barrier to the cylinder liner, and quenching the engine block. The insulating barrier provides a lower cooling rate to the second material forming the cylinder liner than a cooling rate for the first material forming the engine block during the quenching.

Abstract: A degassing and grain refinement system for a cast aluminum-based component and a method of achieving both hydrogen gas presence reduction and grain size reduction in a cast aluminum-based component. Ultrasonic vibrations are imparted to both the liquid metal travel path from its source to the mold to achieve the reduction in hydrogen gas in the molten metal, as well as to one or more locations within the mold to achieve relatively small and equiaxed grains in the component upon solidification.

Abstract: 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.

Abstract: A method of improving riser feedability in semi-permanent mold casting is disclosed. The method includes providing a first receptacle fluidly connected to a mold cavity and providing a second receptacle fluidly connected to a riser. Further, the method includes delivering molten metal to the first receptacle and conveying the molten metal into the mold cavity through a sprue. Delivery of molten metal to the first receptacle is terminated when the mold cavity reaches a predetermined fill level delivery of molten metal to the second receptacle is initiated. In certain embodiments, the first receptacle and the second receptacle are combined into a single receptacle and the sprue is connected to the mold cavity through a lower runner and is connected to the riser through an upper runner.
