    Abstract: The invention relates to a process for producing an alloy based on titanium aluminides. Here, metal droplets are obtained from a titanium aluminide metal melt, in particular using the gas atomization process, the metal droplets are enriched with halogens by exposure to a halogen-containing gas so that halogen-enriched titanium aluminide metal droplets are obtained and the alloy is subsequently formed from the halogen-enriched titanium aluminide metal droplets by pressing, preferably hot isostatic pressing. In further embodiments of the process, pulverulent titanium aluminide, in particular titanium aluminide metal powder, is heated in a, preferably closed, vessel for a predetermined time, where a halogen-enriched atmosphere has been or is provided in the vessel so that halogen-enriched titanium aluminide metal powder is formed during the heating time, or metal droplets are obtained from a titanium aluminide metal melt, in particular using the gas atomization process, the metal droplets are enriched with halogens by exposure to a halogen-containing gas so that halogen-enriched titanium aluminide metal droplets are formed, with the alloy being subsequently formed in each case from the halogen-enriched titanium aluminide metal droplets by pressing, preferably hot isostatic pressing.

    Abstract: The invention describes alloyed zinc powders for alkaline batteries. The powders have a high pyknometer density as a consequence of the presence of only a limited quantity of pores. This high pyknometer density results in strongly reduced gassing after partial discharge of the powders. Also, a process for the manufacturing of a zinc alloy powder for alkaline batteries is disclosed, comprising the step of atomising a zinc alloy, characterised in that the atomising process has a flow rate of at least 700 kg/h, and preferably at least 1000, 1100 or even 1650 kg/h. In one embodiment, the atomising process is performed in a controlled atmosphere, wherein the oxygen content is less than 4 % by volume, and preferably between 0.2 and 3.5 %. The atomising process can be a centrifugal atomisation process. In the atomising process, the zinc alloy consists either of: a) 0.005 - 2 % by weight of indium, and 0.005 - 0.2 % by weight of either one of Al and Bi; or b) 0.005 - 2 % by weight of indium, and 0.005 - 0.2 % by weight of Bi, and 0.001 - 0.5 % of either one or both of Al and Ca; or c) 0.005 - 2 % by weight of either one or both of Bi and Al; and 0 - 0.5 % by weight of Pb, the remainder being zinc.
