| description | The invention discloses a yttrium-tungsten-containing bar billet and a preparation method and application thereof, and relates to the technical field of tungsten products, and the yttrium-tungsten-containing bar billet is made of tungsten alloy. The tungsten alloy comprises yttrium oxide; the mass percent of yttrium oxide in the tungsten alloy is 0.5%-1.2%; the average grain size of the yttrium-tungsten-containing bar billet is 6000/mm < 2 > or above. The tungsten alloy is prepared by adding the yttrium element into tungsten, yttrium oxide formed by the yttrium element serves as second-phase particles, growth of tungsten grains in the sintering process is restrained, the alloy with fine grains is obtained, the average grain size of the yttrium-containing tungsten bar billet is further controlled, and therefore the high-strength tungsten alloy wire is prepared.
