Title: Improvements in or relating to the production of magnesuim base alloys
IPC: C22C1/02
Filed: 1950-02-21
Abstract: A salt for introducing Zr into Mg-base alloys consists of a fused mixture of ZrCl4 and KF within the range of weight ratios of 0.75:1 to 4:1.  The salt mixture may also contain a heavy salt such as up to 30 per cent of BaCl2 to increase its specific gravity.  Up to 2/3 by weight of BaCl2 may be replaced by a similar amount of BaF2.  Up to 30 per cent by weight of inspissating agents may also be included, e.g. up to 20 per cent of MgF2 which should be first calcined at 600-800 DEG C, up to 6 per cent AlF3, up to 10 per cent CaF2 or up to 25 per cent ZrO2.  Up to about 7 per cent of reducible salts of Be may be included.  MgO which may be present as an impurity may be present up to 1 per cent.  The salt mixture may be prepared by intimately mixing about 1 part by weight of previously dried KF and 2 parts by weight of ZrCl4 in a warm crucible, using 5-25 per cent of the total ZrCl4 for this purpose, then mixing or layering substantially all the remaining constituents leaving for a top layer a small amount of KF or mixture of KF and ZrO2, closing the crucible except for a small vent, gently heating until exothermic action occurs, strring the top crust into the molten mixture and finally mixing in other constituents of the salt, if any.  The salt may be used to add Zr to Mg or to Mg alloys containing one or more of Zn, Cd, Ag, Tl, Th, Cu, Bi, Be, Pb, Li, p  Ca, Ce or other rare-earth metals.  The molten or solid salt mixture may be stirred into molten Mg or Mg alloy at a temperature of 760-820 DEG C for 1-10 minutes, allowed to settle within the same temperature range for up to 20 minutes or longer and the stirring and settling operations are repeated if necessary.  Specification 652,229 is referred to.  The Provisional Specification describes also the use of BaCl2 in amount 5-40 per cent, MgF2 up to 20 per cent and CaF2 up to 20 per cent by weight of the whole.
