accumulative roll bonding (arb) was used to fabricate the cu-zn multilayer and cu-zn solid solution. a lamellar structure with the hardness of about 130 vhn was formed after eight arb cycles. following to the suitable heat treatment, a solid solution with a uniform microstructure and hardness of about 57 vhn was produced. the dominant wear mechanism in the arb processed multilayer was found to ...

This paper investigates the phenomenon of cover spalling in reinforced concrete induced by bond or action an inner pressure. research is based on experimental programme comprising a series tests and with inner-pressure cylindrical openings. The test (aimed at representing conditions occurring for instance due to corrosion reinforcement) was performed hydraulic inflator devices embedded within o...
