Investigation of microstructure and mechanical properties of low carbon steel sheets after severe plastic deformation in corrugation dies
Recently, bulk nano-structured materials produced by severe plastic deformation (SPD) have attracted scientists attention. Materials produced by SPD are of great importance because of (1) non-porous structure, (2) great mechanical properties such as high strength and toughness and (3) proper dimension for mechanical and physical testing. Several methods have been introduced for imposing the s...
متن کاملGround Deformation Monitoring Exploiting SAR Permanent Scatterers
The detection of ground deformation phenomena exhibiting a time non-uniform behavior by means of the Permanent Scatterers technique is addressed in this presentation. Simple but effective models are discussed showing significant results obtained.
متن کاملA Steel Wire Stress Measuring Sensor Based on the Static Magnetization by Permanent Magnets
A new stress measuring sensor is proposed to evaluate the axial stress in steel wires. Without using excitation and induction coils, the sensor mainly consists of a static magnetization unit made of permanent magnets and a magnetic field measurement unit containing Hall element arrays. Firstly, the principle is illustrated in detail. Under the excitation of the magnetization unit, a spatially v...
متن کاملEffect of Changing Strain Rate on Flow Stress during Hot Deformation of Type 316L Stainless Steel
In industrial rolling, changes in strain rate and temperature occur with strain during passes, and between one pass and the next. Plane strain compression testing has been used with ramped changes in strain rate during deformation, and with changes in strain rate between two deformations to study their effects on flow stress. No systematic deviations from a mechanical equation of state were fou...
متن کاملCorrosion in Concrete Structures with Permanent Deformation in Marine Environment
Concrete is usually highly alkaline (pH around 12), thus protecting reinforcement against corrosion. The occurrence of oxides is favored when the medium pH surrounding the bar is in values near to 9 or lower. Aggressive substances for reinforcements generally enter concrete through its pore structure, and cracks tend to decrease pH, stimulating corrosion process. There are several causes for cr...
