Copper Spinodal Alloys: Part Two
During the cycle of hardening, the featureless homogeneous starting microstructure remains optically featureless until peak hardness is attained.It was discovered that copper-based spinodal alloys exhibit tribological properties that facilitate their application in lubricated, as well as non-lubricated, bearing applications.
This article examines copper-tin alloys, commonly known as bronzes, which have significant industrial applications within specific tin content ranges. The constitutional diagram of these alloys reveals a complex relationship between composition and microstructure. As tin is added to copper, various solid solutions form (designated as α, β, γ, etc.), each with distinct properties.
This comprehensive analysis explores the composition, properties, and industrial applications of copper-zinc alloys, commonly known as brasses. The article examines how varying zinc content and processing methods influence the mechanical properties and microstructure of different brass types. Focusing on industrially significant compositions, from red brass to brazing solder, the study details the relationship between constituent phases (α, β, γ) and material characteristics.
Corson bronze, a copper-nickel-silicon alloy system, represents a significant advancement in metallurgy by maintaining copper's excellent electrical and thermal conductivity while providing enhanced mechanical properties suitable for demanding industrial applications. Developed and patented by Michael Corson in 1928, this alloy system addresses the fundamental challenge of pure copper's insufficient strength for applications such as injection molding cores and cavities.
Die Casting of Aluminum Alloys: Part One
Aluminum castings are used for many industrial applications, for example in the automotive industry, applications includes wheels, cylinder blocks and heads, pistons, brake cylinders, and suspension arms. The substitution of aluminum cast components for ferrous castings in the automotive sector is predicted to continue to grow as automakers continue to seek opportunities to reduce vehicular weight.
