VERSUTO, B. C. B. Microstructural and mechanical characterization of flash-welded joints in HSLA steels. 2010. 89 p. Dissertation (Master of Science) – Esco la de Engenharia de Lorena, Universidade de São Paulo, Lorena, 2010. The HSLA steels have been increasingly highlighted in the production of automotive parts. Their attractives are high yield and ultimate stren gths, chemical resistance, weldability and formability. These features make the HSLA steels an important item in the development of new products, design for cost reduction and process improvement. The technological innovations and product requirements have lead the industries to seek for new materials with properties that could meet the design specification s. The objective of this work is to understand the microstructure and the mechanical be havior of the weld zone of two types of HSLA steels and compare with the current steel (SAE 1010AA) used in the manufature of rim wheels for truck and bus. The welding process used i this study is known as Flash weld, which is commonly used in the manufacture of wheel rims. The chosen HSLA steels are the RD480 (From CSN Inc.) and S275JR (From CST Inc.). T he welded joints are characterized by means of notched and unotched tensile tests, imp act tests and fracture toughness evaluation through CTOD measurements. The results obtained in mechanical testing and analysis showed that microetrutura studied HSLA ste el have mechanical properties that make them great options in replacing steel SAE1010A A in the production of wheel rims to tubeless. This work was supported by IOCHPE-MAXION, division of wheels and chassis.
