Understanding the Cu-Zn brass alloys using a short-range-order cluster model: significance of specific compositions of industrial alloys

Metallic alloys show complex chemistries that are not yet understood so far. It has been widely accepted that behind the composition selection lies a short-range-order mechanism for solid solutions. The present paper addresses this fundamental question by examining the face-centered-cubic Cu-Zn α-brasses. A new structural approach, the cluster-plus-glue-atom model, is introduced, which suits sp...

Contribution to the knowledge of the Cu–Sn–Zn system for compositions close to brass alloys

The effect of tin content in the equilibrium phases of the Cu–Zn-based alloys, within the range of chemical compositions with interest to brass producers is described. For this purpose, ternary alloys with copper contents between 55.4 and 67.5 wt.% and tin contents up to 5.30 wt.% have been studied. The chemical composition of each alloy has been determined by X-ray fluorescence spectrometry (X...

Sympathy or Brass Tacks

as A regional social worker for the Spastics Society I am increasingly aware of the diversity of my clients' needs, their dependence for facilities on specific geographical areas and the way local authorities interpret the statutory provisions. The knowledge that spasticity is irreversible makes an immediate impact. However I try I know I cannot change the status quo and this is the premise on ...

With the rapid advances in tumor genetics, an increasing number of amplifications have been identified in various human neoplasms (4). Examples of oncogenes amplified in tumors include N-myc and HER-2/neu, which have been proposed as prognostic markers in neuroblastoma and breast cancer, respectively (5,7). To date, most of the information on the amplification of genes has been gathered from co...
