Evaluation of Residual Stress on Steel Parts Welded and Milled

Autor: Frederico Ozanan Neves, Antônio Célio Moreira Junior, Alex Sander Chaves da Silva

Publikováno v: Advances in Materials Science and Engineering, Vol 2018 (2018)

Welded parts are common in mechanical engineering. As all manufactured parts, they also present residual stresses introduced by the corresponding manufacturing process. Residual stresses can be beneficial or not because they can increase or reduce th

Influence of Heat Treatment on Residual Stress in Cold-Forged Parts

Autor: Frederico Ozanan Neves, Thiago Luis Lara Oliviera, Durval Uchoas Braga, Alex Sander Chaves da Silva

Publikováno v: Advances in Materials Science and Engineering, Vol 2014 (2014)

Residual stresses are those stresses that remain in a body when there is no external load applied. Numerous factors can induce residual stresses in the material, including cold forming. Thermal treatments of steel are widely used because they can imp

Evaluation of Hole Quality in Hardened Steel with High-Speed Drilling Using Different Cooling Systems

Autor: Lincoln Cardoso Brandão, Frederico Ozanan Neves, Gregório Christo Nocelli

Publikováno v: Advances in Mechanical Engineering, Vol 3 (2011)

This work evaluates the hole quality on AISI H13 hardened steel using high-speed drilling. Specimens were machined with new and worn out drills with 8.6 mm diameter and (TiAl)N coating. Two levels of cutting speed and three levels of cooling/lubricat

Heat Treatment and Lubrication Analysis of the Surface Integrity of Cold Extruded Metals

Autor: Antonio Carlos Ancelotti Junior, Thalita Cristina De Paula, Frederico Ozanan Neves, Thiago Luiz Lara Oliveira

Publikováno v: International Journal of Precision Engineering and Manufacturing-Green Technology. 7:329-336

Cold forming is a process which is largely employed in industry. Thisprocess may have impacts on mechanical properties and surface integrity. This paper presents a study on Surface Integrity (SI) within the context of cold extruded billets with two d
