93W-Y2O3 was designed and studied,which was fabricated via pre-sintering at 1200℃ in hydrogen,and then sintering at 1480 ℃ and finally annealing at 1100℃ in vacuum using powder metallurgy routes in order to promote "self-sharpening" of 93WNiFe penetrator when it penetrates armor.
为了提高传统93WNiFe合金在侵彻装甲时的自锐化能力,采用粉末冶金的方法,在传统93WNiFe合金中加入了少量的Y2O3,经过1200℃氢气氛中预烧和1480℃烧结以及1100℃的真空退火热处理后烧结成为93W-Y2O3合金,其密度达到了理论密度的98。

The rate of penetration of PDC bits relates closely to its self-sharpening property.
复合片钻头的钻速与其切削齿的自锐性密切相关,钻头台架试验反映了这种内在联系,并用平均钻速((?))和平均钻速变化率((?))等指标对复合片自锐性能进行描述与评价。
