Experimental Investigation on Flame Straightening of Corrosion Resistant Structural Steel Sheet Used for Rolling Stock

Flame straightening is a common procedure used for repair work in steel components. It is based on heating a local region of the part by means of a flame torch. Due to the obstruction of the heat expansion, upsetting occurs in the work material. During cooling of the squashed zone shrinkage occurs and that is associated with tension forces which lead to the desired deformation. This process is ...

Joining of Cold-Reduced Carbon Steel Sheet and Aluminum Sheet by Impulsive Riveting Method and Punch Riveting Method

The impulsive riveting method is described as the punching and joining of sheet metal carried out using the impulsive energy of a weight accelerated by an air compressor. Parts are held together between the rivet and rivet-holder. A hole is made in the sheets by the high speed collision of rivet and a weight (approximately 100 m/s or more). Another method, punch riveting, joins the sheets by pr...

Optimization of continual production of CNTs by CVD method using Radial Basic Function (RBF) neural network and the Bees Algorithm

Optimization of continuous synthesis of high purity carbon nanotubes (CNTs) using chemical vapour deposition (CVD) method was studied experimentally and theoretically. Iron pentacarbonyl (Fe(CO)5), acetylene (C2H2) and Ar were used as the catalyst source, carbon source and carrier gas respectively. The synthesis temperature and flow rates of Ar and acetylene were optimized to produce CNTs at a ...

Investigation of Transformation Induced Plasticity in High Al–low Si TRIP Steel

This study was conducted in order to investigate the influence of plastic deformation on the transformation of retained austenite in a TRIP steel with a high content of Al and a low content of Si. To the aim, appropriate treatments were used to produce the starting material (TRIP steel). The microstructure of the obtained steel was composed of bainite and phases including ferrite and retained a...
