Anode material and preparation method thereof

The invention discloses an anode material and a preparation method thereof. The anode material comprises tungsten grains and a K element distributed in the grain boundary of the tungsten grains, the average grain size of the tungsten grains is within the range of 60 microns-120 microns, the average grain length-width ratio of the tungsten grains is 5:1 or above, and the anode material is made through a static liquid rapid forging process, recrystallization annealing and rotary hammer deformation. According to the anode material, the grain size and grain length-width ratio of a tungsten-containing substrate can be controlled effectively, and comprehensive performance of the machining knife loss, high temperature resistant stability and electron bombardment resistance of the prepared anode material is promoted significantly. 本发明公开了种阳极材料及其制备方法。该阳极材料包括平均晶粒尺寸在60μm～120μm范围和平均晶粒长宽比在5:1以上的钨晶粒和分布在所述钨晶粒晶界的K元素，并采用静液快速锻造工艺、再结晶退火、旋锤变形制成。该阳极材料可有效控制含钨基材晶粒尺寸及晶粒长宽比，明显提升制得的阳极材料的机加工刀损、耐高温稳定性和耐电子轰击能力的综合性能。
