1. Método innovador de ensayos de impacto en altas temperaturas aplicado en aceros al carbono
ABSTRACT In this paper, an innovative method of impact tests at high temperature on sub-size Charpy V notched specimens is applied. The innovation lies in the method of heating the specimen, which is performed in situ on a Charpy impact machine type by alternating electrical current through the specimen. The specimens are heated in a few seconds (v=32 ºC/s)

2. Soldabilidade dos aços DUAL-PHASE 600 e 800 via processo de soldagem a pontos média freqüência corrente contínua (MFDC) e corrente alternada (AC) / Weldability of 600 and 800 Dual-Phase Steels by Using Resistance Spot Welding Medium Frequency Direct Current (MFDC) and Alternating Current (AC)
Dual-Phase steels have been developed to match the automotive-industry need of highresistance materials that lead to weight reduction and, therefore, reducing emissions. Specifically, in the use Resistance Spot Welding (RSW) process, the Medium Frequency Direct Current (MFDC) equipment has been largely introduced in the automotive industry without, however,
