Abstract: An electrically conductive aluminum diecast alloy and an induction motor rotor made of the diecast aluminum alloy. The aluminum alloy includes commercially pure aluminum and a sufficient weight percent (wt%) of Copper (Cu), Magnesium (Mg), and Silicon (Si) to precipitate a 0.1 wt% to 5.0 wt% of a thermally stable Q-phase precipitate, AlwCuxMgySiz, after age hardening. Wherein w = about 14.3 at% to about 23.82 at% of Al; x = about 5.90 at% to about 9.52 at% of Cu; y = about 35.30 at% to about 42.85 at% of Mg; and z = about 28.57 at% to about 35.30 at% of Si. The induction motor rotor includes an aluminum squirrel cage rotor diecast onto a laminated electrical steel. The aluminum diecast squirrel cage rotor includes about 1.0 wt% of thermally stable Al5Cu2Mg8Si6 after age hardening.

Abstract: The concepts described herein provide a method, system, and apparatus for joining, via welding, first and second members fabricated from an aluminum alloy including aluminum, zinc, and manganese, such as 7000-series aluminum alloys, and a resultant workpiece. A junction is formed by a first member being disposed contiguously to a second member. A welding machine generates a weld pool at the junction that includes liquified aluminum alloy. An ultrasonic transducer directs ultrasonic energy in proximity to the weld pool. In some embodiments, an electro-magnetic transducer directs electro-magnetic energy in proximity to the weld pool. The first member is fused to the second member at the junction upon solidification of the weld pool.

Abstract: A high heat-absorption casting core for manufacturing a cast component includes a core body. The core body has at least a portion thereof defined by metal powder. The metal powder is configured to absorb heat energy from the cast component during cooling of the component and solidification thereof. The core body may be additionally defined by a sand fraction in contact with the metal powder fraction. A system and a method for manufacturing a cast component using the high heat-absorption casting core are also envisioned.

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.
