RESUMO Este trabalho tem como objetivo investigar o aumento da temperatura em chapas de aço inoxidável AISI 430 durante ensaio tração para as seguintes taxas deformação: 0,001; 0,01 e 0,1 s-1. Para registrar a evolução até fratura dos corpos prova, foi utilizada uma termocâmera por infravermelho. Os resultados obtidos pela técnica termografia infravermelho mostraram um gradual uniforme encruame...

Abstract Carburization assisted by laser processing is a promising method to strengthen metallic materials. Direct beam carburization implemented for the first time on thin AISI 430 ferritic stainless steel (FSS) sheets with graphite coating under different conditions. Microstructural morphology, phase constitution, carbon content, microhardness, and tensile behavior are investigated evaluate e...

In this study, the effect of shallow cryogenic treatment on friction coefficient AISI 430 ferritic stainless steel was investigated. The experiments were carried out in a ball-on-disc wear tester under 5 N load at 400 rpm. As result tests, study examined surface topography traces, abrasion profile, microscopic images and hardness change traces. After applying treatment, samples increased by 7.5...

The influences of ultrasonic vibration during cold metal transfer welding process on the microstructure, element distribution and pitting resistance AISI 430 ferritic stainless steel joints with ER 308L as filler were investigated. combined effects mechanical vibration, acoustic streaming cavitation significantly refined primary ferrite grain in weld then impacted subsequent solid-phase transit...
