    In order to determine the workability of cast iron with spheroidal graphite,the following tests have been conducted on this material in the as-cast and annealed condition:tensile tests,compression tests,Charpy impact tests,impacttensile tests,twisting tests,upsetting tests under the drop hammer and small-scaledrolling tests.Results from these tests show that the best hot-working temperature rangeof this material varies somewhat with the stress system applied and the speed ofworking,and in general lies between 700° and 1100℃.Within this temperaturerange,the maximum amount of working permissible for a single working operationvaries considerably with the stress system applied.Under tensile stresses,thismaximum amount of working lies between 28 and 57.6%;under predominentlycompressive stresses,it lies between 58.5 and 72.9%;while in the small-scaledrolling tests,the maximum reduction in thickness permissible for a single passlies between 38.6 and 44.3%.The maximum amount of working permissible is alsoaffected by the speed of working,being greater at lower speeds.Tests on industrial scale show that the upsetting and small-scaled rollingtests give results nearest to those from industrial tests.Charpy impact tests,impacttensile tests,upsetting tests and small-scaled rolling tests show more prominentlythe best hot-working temperature range than the other tests conducted.Results of the present research also indicate that cast iron with spheroidal graphitehas a higher strength and workability when subjected to compressive stresses thanto tensile stresses,that a brittle temperature range has been recorded between200° and 650℃,which varies with the speed of test.Judging from the variationof the resistance to deformation with the change of temperature and the speedeffect,this phenomenon is associated with blue brittleness.

    The application of the conventional method of fatigue test to sintered powder materials has the limitation that it does not reveal the complete process of generation of the initiation and propagation of the fatigue crack, as a result of this limitation, the morphology of the fatigue crack is not usually disclosed to the observer.By using a light weight impact hammer, the authors, however, have been able to overcome the limitations of the conventional test method and obtained the complete crack morphology in the specimen.In this study, the authors find that when the propagation of the crack is checked by some inclusions or porosities, it usually changes it direction or comes to a temporary stop.The appearence of the selected surface and of the fractured specimen has been observed with TEM and SEM, and numerous fractographs have been taken.

    应用传统试验钢材的手段去试验粉末热锻钢有一定的局限性,就是不容易得到裂纹萌生→扩展的完整过程,也难以见到比较完整的疲劳裂纹形态和各个区域分界清楚的断口形貌. 我们认为大幅度降低应力水平是研究粉末热锻钢疲劳断裂实质的关键手段之一。为此目的,改制了多冲机的冲锤、夹具和冲击刀口。试验得出了冲击次数与疲劳裂纹长度关系曲线,以及裂纹源区和扩展区与最后迅速断裂区层次分明的疲劳断口. 用TEM和SEM以及电子探针方法对断口进行了检查,探讨了粉末热锻钢的断裂机理.并拍摄了大量裂纹扩展形态图片.发现这种材料的裂纹萌生、扩展有着许多特点.

    The mechanism of influence of high energy rate extrusion on microstructure and mechanical properties of the 1Cr13rotary blade was studied by means of metallographic analysis, grid methed experiments and site measurements. The results showled that the grains of blade after hammer or press forging are ecarse and the mechanical properties are low due to small deformation ard high finish temperature. But after high energy rate forging the grains and the martensite structure are fine so that the mechanical properties are much higher due to greater deformation especially shear of the metal on throat of the extrusion die and addition ally faster cooling rate on the blade. This serves the basis that only a rewoving stress tempering is needed after high energy rate forging of the blades from 1Cr13 stainless steel instead of quenching through hammer or press forging.

    本文通过金相组织分析,网格变形试验和现场测试,论述了高速锤挤压变形对1Cr13动叶片组织和性能的影响。结果指出:锤或压力机上模鍛的叶片由于叶背处变形程度很小和常因终鍛温度较高,鍛后晶粒粗大,机械性能较低;而高速锤挤压的叶片由于流经孔口时有较大的变形,尤其是有较大的剪切变形,加之在模具内金属冷却速度较快,故可得到细小的晶粒和细小马氏体组织,从而有较高的机械性能。这就为用高速锤挤压1Cr13不锈钢叶片后只进行去应力回火处理,代替用常规的模鍛设备在模锻2Cr13不锈钢叶片后需经调质处理的老工艺提供了依据。
