    摘要： The invention relates to mixtures of metal, alloy or composite powders which have a mean particle diameter D50 of not more than 75 μm, preferably not more than 25 μm, and are produced in a process in which a starting powder is firstly deformed to give platelet-like particles and these are then comminuted in the presence of milling aids together with further additives and also the use of these powder mixtures and shaped articles produced therefrom.

    摘要翻译： 本发明涉及平均粒径D50不大于75μm，优选不超过25μm的金属，合金或复合粉末的混合物，并且是以首先变形起始粉末以产生血小板的方法生产的 然后在研磨助剂和其它添加剂的存在下粉碎这些颗粒，并且还使用由其制备的这些粉末混合物和成型制品。
