| 6. | As an example , optimum microstructures of ductile iron were designed according to the observations on the microprocesses of fracture in the last part of this thesis 本文最后根据球铁断裂微观机理研究的结果,对球铁进行优化组织设计,以期显著提高球铁强韧性。 |
| 7. | Another research finds that the ball mechanic milling on high - cr alloy powders has obvious effects on strengthening and toughening of the material . it is an effective approach for the materials " strengthening and toughening 还发现,机械球磨合金粉末对高铬覆层材料的强化和韧化有明显作用,是实现材料强韧性的有效途经。 |
| 8. | Microstructure refinement can lead to an increase in both strength and toughness in the methods enhancing the mechanical properties of steel materials , so the microstructure refinement is a important direction of material research 在众多提高钢铁材料强韧性的方法中,细化组织是唯一提高强度而不降低韧性的方法。因此,钢铁材料组织超细化是当今材料研究的重要方向。 |
| 9. | Up to now , there is quite few studies on strength and toughness of this materials , and the mechanism of facture is not well determined . so the ways to improve the strength and toughness of this materials are quite eyeless 目前国内外对这种材料强韧性的研究相对较少,对其断裂失效模式、断裂机理没有明确统一的定论,因而其改善韧性的方法缺乏理论指导而带有一定的盲目性。 |
| 10. | It is possible to suppress brittleness and increase the strength and toughness by optimizing heat treatment process especially for microalloyed steels 50crv . in addition , heat processing for microalloyed steels socrv was investigated in principle in the paper 通过微合金元素产生的沉淀强化,可以弥补回火造成的强韧性的下降,设计最佳的热处理综合工艺将可以同时提高钢的强度和韧性,同时还可保持一定的硬度。 |
