Formation and Thermodynamic Analyses of Inclusions in Ti-Containing Steel Weld Metals with Different Al Contents

espanolSe prepararon muestras de metales soldadura acero que contienen Ti con contenidos Al 0,01-0,085%. Los efectos del contenido en los sobre la evolucion las inclusiones se investigaron detalle mediante calculos termodinamicos junto microanalisis sonda electrones. resultados muestran el 0,01% metal estan compuestas principalmente ilmenita mas cantidades (Mn-Si-Al) -oxido y titanial-spinel. Cuando aumenta hasta un 0,035%, forma una mayor cantidad corindon pequena pseudobrookita. En 0,085% Al. Al, fase oxido desaparece por completo sustancial corindon, ademas minima Ti3O5, MnTi2O4 MnTiO3 son componentes principales soluciones solidas pseudobrookita, titanial_spinel e ilmenita, respectivamente. Titanial-spinel tienen altas Mn, pero niveles bajos comparacion EnglishThe Ti-containing steel weld metals with contents of 0.01-0.085% were prepared. The effects in on the inclusions evolution detail investigated by means thermodynamic calculations coupled electron probe micro-analyses. results show that 0.01% are mainly composed ilmenite more amounts (Mn-Si-Al)-oxide and When content is increased up to 0.035%, a amount corundum small pseudobrookite formed. In 0.085% metal, phase disappears completely, contain substantial corundum, addition minimal pseudobrookite. primary constituents pseudobrookite, solid solutions, respectively. Titanial_spinel have higher but lower levels compared
