Abstract (en)
[origin: WO2014027184A1] A method of producing a master alloy for refining the grain size of a bulk alloy comprises the step of providing an Al-B alloy and adding Nb in elemental form to form an Al-Nb-B master alloy. The Al-B alloy may be prepared by providing an Al-B alloy with a higher boron content than is required and diluting it with elemental aluminium.
