    摘要:

    研究了K—RE變質處理對Fe—V—W—Mo合金機械性能和熱物理性能的影響。結果發(fā)現，Fe-V-W-Mo合金經K—RE變質處理后，硬度和紅硬性略有增加，沖擊韌性提高41．82％，達到11．09J／cm^2，耐磨性和導熱系數提高，熱膨脹系數減小。分析了K—RE改善Fe—V—W—Mo合金性能的機理，并制造了K—RE變質Fe—V—W—Mo合金軋輥，在熱軋生產中使用獲得了良好的效果。

    Abstract:

    The effects of potassium and rare earth (RE) on the mechanical properties and thermal physical properties of Fe-V-W-Mo alloy were researched. The results show that the hardness and hot hardness of modified Fe-V-W-Mo alloy slightly increase, impact toughness greatly increase by 41.82% and reach to 11.09 J/cm2. K-RE modification is able to increase the wear resistance and heat conductivity coefficient and decrease heat expansion coefficient. The mechanism that K-RE improved the properties of Fe-V-W-Mo alloy was analysed. Fe-V-W-Mo alloy roll modified by K-RE was manufactured by means of common centrifugal casting method, its service effect was very excellent in hot rolling steel.
