| 9. | Abstract : the progress of alloying steel with copper is introduced , the benefits of copper in steels are investigated . it is pointed out that copper in steels can improve corrosion resistance , strength , weldability , formability , machinability and so on 文摘:介绍了用铜合金化钢的新进展,探讨了铜在钢中的有益作用,指出在钢中加入铜,可以提高钢的耐蚀性、强度,改善焊接性、成型性与机加工性等。 |
| 10. | Based on results of a large number of runs , the following conclusions can be made at this stage of research . the fensile strength of the new steel added micro alloyed process is 1 . 1 times . as large as that of original specimens . impact toughness improved by 300 % , elongation ratio increased by 79 % hardness has a little improvement than before . the obtained results demonstrate that the new material has supermechanical properties with the addition of the micro allolyed process 并在常温下对合金化钢的力学性能进行了测试。试验结果表明,通过微合金化抗拉强度提高了10 . 2 % ,冲击韧性提高300 % ,延伸率提高了79 . 5 % ,硬度稍有提高。总之,加入复合稀土、钒、镍等微合金元素提高了材料的综合机械性能。 |
