2. Fatigue failure analysis of HSLA steel sheets holed by conventional and flow drilling processes
ABSTRACT Flow drilling process produces bushes for removable joints that can be threaded by forming tapping process, reducing stages in production of components of automobile industry and in construction sheds. High strength and low alloy steels (HSLA) are employed on several applications in the processing industry. Benefits provided by these materials make

3. Microstructural and Micromechanical Effects of Cold Roll-forming on High Strength Dual Phase Steels
In this work correlation between the 1000 MPa dual phase (DP) steel microstructure and the strain gained after roll-forming process have been studied by both microstructural and micromechanical analysis. The scanning electron microscope (SEM) inspection in the bent area reveals changes in the ferrite-martensitic microstructure. The plastic deformation of DP

4. The effect of cold forming on structure and properties of 32 CDV 13 steel by radial forging process
The present study focuses on the effect of various degrees of plastic deformation generated by cold radial forging on the mechanical properties and the fracture morphology of 32 CDV 13 steel. The cold forging percentage was evaluated for 17.45, 33.30, 42.0 and 46.47 %. The microstructural analysis of the steel shows tempered martensite. The tensile strength,

5. Some aspects of barreling in sintered plain carbon steel powder metallurgy preforms during cold upsetting
The present research establishes a relationship of bulged diameter with densification and hydrostatic stress in forming of sintered iron (Fe) powder metallurgy preforms cold upset under two different frictional conditions, namely, nil/no and graphite lubricant condition. Sintered plain carbon steel cylindrical preforms with carbon (C) contents of 0, 0.35, 0.

6. A contribution to the study on cold forging of steel helical gears / Uma contribuição ao estudo do forjamento a frio de engrenagens helicoidais
The forging processes are classified in hot forging, warm forging, and cold forging, that usually provide products that need some further machining operations to achieve manufactured part specifications. Cold forging asks for a special attention when manufacturing complex geometry parts, because its limitation with the forgeability of the workpiece material,

7. Analise numerica e experimental do cravamento de componentes mecanicos tubulares em haste com ponta esferica / Numerical and experimental analysis of tubular metallic parts indented with spherical punchs
Crimping is a cold metal forming process that presents low costs for use in holding tubular components. The type of crimping analyzed is used in projects of components that transmit rotating motion, such as joining systems of brake pedals. If the joining clearance, in this case, is less than 0,02mm the brake movement will be restrained and may not close the

8. The effect of cyclic torsion on the dislocation structure of drawn mild steel
Cold forming is usually associated with the "work hardening" of the material being formed. The work hardening behavior of metals subject to complex processing paths is different from that in monotonic deformation. The results show that, after some initial hardening, there is a possibility that further deformation will cause softening in the material ("work s

10. CONECTOR DE CISALHAMENTO EM PERFIL FORMADO A FRIO: ANÁLISE VIA MODELAGEM COMPUTACIONAL
In a composite system, a steel beam (laminated, welded or cold formed) is associated with a concrete slab, forming a composite beam. The interaction between concrete and steel can be mechanical, by friction or, in some cases, only by adherence. One of the major advantages of the composite beams is the increase in strength and stiffness due to association of
