摘要： A vibration-proof tungsten wire which forms, in cases where the diameter of the wire is D mm and when an electric current corresponding to 90% of the fusion current value is passed therethrough for 5 minutes, a wire havinga crystal grain boundary at which bubbles of 0.3 .mu.m or less in diameter are dispersed in bubble rows with lengths of (0.39/D).sup.2 .times.3 .mu.m or more arrayed in the wire axis direction of said crystal grain boundary, and bubbles of 0.2 .mu.m or less in diameter are randomly dispersed; anda crystal grain in which bubbles of 0.3 .mu.m or less in diameter are dispersed in rows with lengths of (0.39/D).sup.2 .times.30 .mu.m or more arrayed in the wire axis direction within said crystal grain, and bubbles of 0.2 .mu.m or less are randomly dispersed;a process for preparing the same; and a tungsten filament obtained from the above-defined wire. The doped tungsten wire of this invention possesses excellent vibration-proof property on lighting as well as high reliability.

摘要： A method for preparing tungsten materials in which tungsten powder obtained by reducing tungsten oxides having doping agents added thereto is washed first with hydrochloric acid having a concentration of not lower than 4% by weight and then with hydrofluoric acid having a concentration of not lower than 3% by weight, and thereafter dried. The above-mentioned washing steps may be carried out at a time by using a mixture of such hydrochloric acid and hydrofluoric acid as specified above. Articles formed by treating tungsten materials obtained by the above-mentioned process are subjected to only a low high temperature deformation.
摘要翻译：一种制备钨材料的方法，其中通过还原添加有掺杂剂的钨氧化物获得的钨粉末首先用浓度不低于4重量％的盐酸洗涤，然后用浓度不低于3的氢氟酸重量％，然后干燥。上述洗涤步骤可以通过使用如上所述的这种盐酸和氢氟酸的混合物一次进行。通过处理通过上述方法获得的钨材料形成的制品仅经受低的高温变形。
