The effects of various conditions on desiliconizing of 2∼7%Si-Cu alloys by heating in nitrogen atmosphere containing 10%Si Cl4 vapour were studied. The results obtained were summarized as follows. The weight decrease by desiliconizing and the depth of desiliconized layers of the samples rose to the maximum at 500°C and 600°C respectively, and were not remarkable at about 800°C. At 500°C the weight change by desiliconizing was the greatest in 5.40%Si alloys, but at 800°C it decreased with increasing silicon content in the alloys. From these results the present authors considered that desiliconizing of Si-Cu alloys with SiCl4 proceeds along the following consecutive reactions,<BR>(This article is not displayable.
