摘要： Processes are provided that include providing a copper-manganese alloy containing copper and manganese and having an amount of manganese that is at least 32 weight percent and not more than 40 weight percent of a combined total amount of the copper and manganese in the copper-manganese alloy, and casting the copper-manganese alloy by multidirectional solidification to produce a product in the form of a casting. The copper-manganese alloy has a composition sufficiently near the congruent melting point of the Cu—Mn alloy system to sufficiently avoid dendritic growth during the multidirectional solidification of the copper-manganese alloy to avoid the formation of microporosity attributable to dendritic growth. The product has a cast microstructure having a cellular and/or planar solidification structure free of dendritic growth and having multidirectional columnar grains.

摘要： The present invention describes an effective grain refining practice for aluminum foundry alloys. The method described herein relies on the control of the Titanium level of the alloy to be grain refined and the addition of boron once it is melted. Boron addition can be made via Al—B master alloys as well as with boron compounds such as KBF4 salt. The boron added into the melt dissolves first and then forms the AlB2 particles that act as potent substrates for the nucleation of aluminum once solidification process starts. The Ti concentration of the alloy must be controlled below 100 ppm for this method to offer effective grain refinement. The boron becomes ineffective when the Ti concentration in the alloy is higher.
