Description

高硬度粉末冶金高速钢件
本发明涉及由粉末冶金法生产的高速钢件，其特征在于具有高硬度和高的耐磨性，尤其是高温下的高硬度和高的耐磨性，适用于制造齿轮切削刀具，例如滚齿刀和其它需要非常高的耐磨性的切削用途。
在需要高硬度和高的耐磨性的切削用途中，刀具在使用中要经受超过1000°F的高温，例如会最高达1200°F，通常采用碳化物制造这些刀具。然而，碳化物材料存在明显的缺点，即难以加工到预计的切削加工构型，尤其是复杂的切削表面，并具有韧性较低的特征，从而使碳化物制成的刀具在使用中易于开裂和发生崩裂。在这些用途中，优选使用高速钢，而不是碳化物，因为与碳化物材料相比，高速钢易于加工成预计的切削加工构型，其韧性大大提高了。然而，高速钢尚未在这些用途中使用，因为高速钢在使用传统的碳化物刀具的高温下，不具有必要的高硬度以及高耐磨性。
因此，本发明的目的在于提供一种由粉末冶金法生产的高速钢件，可用于制造齿轮切削刀具，例如滚齿刀和其它需要高耐磨性的切削用途。该材料应能够达到并保持在碳化物切削刀具应用中所预期的高温下的高硬度，而又具有高速钢在韧性和加工性能方面的长处。
本发明大体涉及一种由粉末冶金法生产的压实的高速钢粉末颗粒的高速钢件。该钢基本由以下成分组成：以重量％计，2.4～3.9的碳、0.8以下的锰、0.8以下的硅、3.75～4.75的铬、9.0～11.5的钨、4.75～10.75的钼、4.0～10.0的钒和8.5～16.0的钴以及任选的2.0～4.0的铌，其余为铁和偶存的杂质。

合金A1a～A1d、A2a～A2e和A3a～A3c都是根据本发明的组成的合金。如表2中所示和图解表示于图1中的回火响应性数据，与现有的工业合金相比，本发明的A1、A2和A3系列合金在最高达1200°F的回火温度下表现出优异的硬度。类似地，如表3所示，本发明的试样A1c、A2a、A2d和A3a也表现出极好的耐磨性，耐磨性采用销式磨损试验和交叉圆柱试验测定。本发明的这些合金中，合金A1显示对回火响应性和耐磨性的最佳组合。合金A2显示在1200°F回火后硬度稍低，但是与合金A1相比，在一定程度上提高了韧性和弯曲破坏强度。然而，如表3和图1中所示，与现有工业合金相比，所有本发明的合金都表现出综合改善了的回火响应性、韧性和耐磨性。
