Approximately 50% of the yield stress is due to the strengthening effect of the grain size. The upper-shelf notch toughness is approximately 250 J, and the transition temperature for ductile to brittle fracture is below-80掳C. The steel has a superior resistance to hydrogen embrittlement. After...
A Novel Approach to the Prediction of Long-Term Creep Fracture, with Application to 18Cr-12Ni-Mo Steel (Bar, Plate, and Tube) The estimation of this model showed that the activation energy for creep was dependent on whether the test stress was above or below the yield stress. ... M.,...
Refers to the stress at which a material begins to deform plastically undertension. For M2, this is typically around2,200 MPa. Compressive Yield Strength of Steel Refers to the stress at which a material begins to deform plastically undercompression. Materials often exhibit higher yield strengths...
The dynamic tensile tests of pure iron and low carbon steel at a strain rate of 30/sec were performed at room temperature and -78°C. The results of measurements of the yield and the flow stress were analyzed on the basis of the Petch equation and discussed with emphasis on the effects ...

Relationship between Yield stress and yield Strength on Various Grade of steel Being Hot rolled Stress is ability of materials to resist failure. The relationship between yield strength and yield stress of various grade of steel being hot rolled is necessary to predetermine the failure of engineering...
The influence of grain size on the mechanical properties ofsteel The grain-size dependence of the cleavage stress is a straightforward consequence of both the Griffith and Orowan fracture criteria, but the Hall-Petch ... M Jr - 《Ductile Brittle Transitions》 被引量: 68发表: 2001年 A composit...
In this study, the 0.2% yield stress of duplex stainless steel was evaluated using a compound Hall–Petch equation. The compound Hall–Petch equation was derived from four types of duplex stainless steel, which contained 0.2–64.4 wt% δ-ferrite phase, had different chemical compositions and were...
