Production of metal billets

摘要

A method of producing semi-finished metal iron or nickel-based products by spray forming in which one or more jets of nitrogen or a nitrogen-containing gas are directed onto a stream of molten alloy to atomise the same. A titanium addition is made to the liquid alloy before spray forming occurs. The atomised liquid or partially solidified droplets of alloy collect on a substrate to produce a semi-finished product.
