US Patent:

20190153579, May 23, 2019

Filed:

Jan 25, 2019

Appl. No.:

16/257446

Inventors:

- Mayfield Heights OH, US
Chad A. Finkbeiner - Highland Heights OH, US
Fritz C. Grensing - Perrysburg OH, US

International Classification:

C22F 1/08
C22C 9/06
C22C 9/02

Abstract:

A spinodal copper-nickel-tin alloy with a combination of improved impact strength, yield strength, and ductility is disclosed. The alloy is formed by process treatment steps including solution annealing, cold working and spinodal hardening. These include such processes as a first heat treatment/homogenization step followed by hot working, solution annealing, cold working, and a second heat treatment/spinodally hardening step. The spinodal alloys so produced are useful for applications demanding enhanced strength and ductility such as for pipes and tubes used in the oil and gas industry.

Abstract:

A piston ring is made from a copper-beryllium alloy. This material permits the top compression ring of a piston to be moved closer to the piston crown, reducing crevice volume and reducing the tendency for pre-ignition. Ignition timing advance can be realized by installing the rings and letting the ECU advance the timing as the sensors allow, increasing efficiency. Also, shorter pistons and longer connecting rods are possible. The shorter pistons reduces the reciprocated mass in the engine and the longer connecting rods reduce the frictional loss caused by radial forces pushing the piston against the liner. Both reducing volume and tendency for pre-ignition increase engine efficiency.
