Hot Forming of Aisi A2 Tool Steel
In order to optimize the hot forming process of tool steels, further improvement of flow stress prediction and additional knowledge on hot deformability, especially at lower and upper limits of the hot working range, are required. The hot working ranges for these steels are very narrow as a consequence of the role of alloying elements, which form carbides. Carbides improve tool steel’s hardenab...
متن کاملFatigue Life of Graphite Powder Mixing Electrical Discharge Machining AISI D2 Tool Steel
The present paper deals with the design of experimental work matrices for two groups of experiments by using Response surface methodology (RSM). The first EDM group was dealt with the use of kerosene dielectric alone, while the second was treated by adding the graphite micro powders mixing to dielectric fluid (PMEDM). The total heat flux generated and fatigue lives after EDM and PMEDM models we...
متن کاملHigh cycle fatigue of electrical-discharge machined AISI D2 tool steel
An analysis of electrical-discharge machined AISI D2 tool steel for high-cycle fatigue is conducted. The damage model was developed to reveal the in£uence of different electrical-discharge machining conditions on the fatigue life. The processed surface layer and the cross-section were examined by scanning electron microscopy (SEM).The experimental results show that the fatigue life of the EDMed...
متن کاملThe Unified Creep-Fatigue Equation for Stainless Steel 316
Background—The creep-fatigue properties of stainless steel 316 are of interest because of the wide use of this material in demanding service environments, such as the nuclear industry. Need—A number of models exist to describe creep-fatigue behaviours, but they are limited by the need to obtain specialized coefficients from a large number of experiments, which are time-consuming and expensive. ...
متن کاملCreep and Fatigue Interaction Behavior in Sanicro 25 Heat Resistant Austenitic Stainless Steel
Sanicro 25 is a newly developed advanced high strength heat resistant austenitic stainless steel. The material shows good resistance to steam oxidation and flue gas corrosion, and has higher creep rupture strength than other austenitic stainless steels available today. It is thus an excellent candidate for superheaters and reheaters for advanced ultra-super critical power plants with efficiency...
