The development of materials which contain the noble metals for use in high temperature strain gauges is reviewed, with particular emphasis being placed upon work done by the Institute of Precious Metals, in China. Three alloy systems displaying excellent resistance to oxidation and good overall properties when used in high temperature straingauges, are singled out for examination. These are pl...

The development of grain size during commercial thermomechanical processing of 6000 series aluminium alloy components has been investigated by combining physical experiments and modelling techniques. A range of grain structures was generated by varying both deformation temperature and heat treatment practice. The different deformation conditions were simulated by finite element modelling, which...

Aluminium alloy components are used in lightweight engineering applications and lack mechanical properties, wear resistance, corrosion resistance. When hard reinforcement particulates dispersed the aluminium matrix alloy, composites (AMCs) formed. This new material exhibits enhanced properties such as better specific stiffness, strength, elastic modulus, lightweight. AMCs have many favorable co...

Elastic-plastic finite-element analysis applied to metalforming allows the real macroscopic properties of the workpiece to be incorporated. This paper presents the results of an experimental study of the initiation of cracking in side-pressing of a heat-treated aluminium alloy (Duralloy 2014). Using an F. E. analysis, these are related to various fracture criteria. It is found that the criterio...
