具体实施方式
以下通过具体实施方式的描述对本发明作进一步说明，但这并非是对本发明的限制，本领域技术人员根据本发明的基本思想，可以做出各种修改或改进，但是只要不脱离本发明的基本思想，均在本发明的范围之内。
实施例1高韧性合金的制备
高韧性合金的组成为(以重量％计)：
0.40％的碳；
0.60％的铬；
0.80％的硅；
0.70％的锰；
1.5％的镍；
0.8％的钼；
0.25％的钒；
0.12％的磷；
0.004％的氮；
0.35％的铜；
0.035％的铝；
0.025％的钛：
0.15％的硫；
0.017％的钴
0.06％的铌；
其余为铁和不可避免的杂质。
将具有上述成分组成的50kg钢料置于30KGSS81-22中频无芯感应电炉中熔融6小时，鉴于合金元素在熔炼过程中会发生氧化烧损，在熔融最后一小时加入钴和铌，钢液温度达到1600℃，随后进行浇铸，在该浇铸中冷却速度为1.8℃/min以形成锭料。将锭料在900℃下保持8小时，然后在550℃下保持60分钟。此后使用500吨锤式锻造机进行热锻，这样制得高韧性合金1。
实施例2高韧性合金2的制备
按照和实施例1相同的方式制备高韧性合金2，不同之处在于不使用钴。
实施例3高韧性合金3的制备
按照和实施例1相同的方式制备高韧性合金3，不同之处在于不使用铌。
实验例1
根据GB/T231.1-2009来测定高韧性合金1-3的布氏硬度。结果如下：高韧性合金1的布氏硬度为289HRC，高韧性合金2的布氏硬度为216HRC，高韧性合金3的布氏硬度为232HRC。高韧性合金1的布氏硬度和高韧性合金2与高韧性合金3相比，有显著性差异(P<0.05)。
