Simulation Study on Thermo-Mechanical Controlled Process of 800 MPa-Grade Steel for Hydropower Penstocks
The thermo-mechanical controlled process (TMCP) of 800-MPa-grade non-quenched tempered steel used for penstocks was simulated on a Gleeble-3500 thermo-mechanical simulator. The effect of the finish cooling temperature (FCT) which ranged from 350–550 ◦C on the microstructure and mechanical properties was studied. The microstructure of TMCP specimens is primarily composed of lath bainite (LB) and...
متن کاملMULTI FRACTURE/DELAMINATION ANALYSIS OF COMPOSITES SUBJECTED TO IMPACT LOADINGS
A combined finite/ discrete element method is presented for modelling of composite specimens subjected to dynamic/impact loadings. The main task is set on developing an algorithm for simulation of potential bonding and debonding/delamination phenomena during impact or general dynamic loading conditions. In addition, full fracture analysis can also be performed. The proposed approach adopts a ge...
متن کاملThermal Stress Resistance to Fracture and its Relation to with Resistance to Thermal Fatigue and Shock
Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...
متن کاملThe Fracture Mechanisms of an Austenitic Heat Resisting Steel in Copper Converter Atmosphere
The openings of Copper converter in Sarcheshmeh Copper Complex in Iranis made of a heat resisting austenitic steel (Fe-25Cr-12Ni) and many failures have been reported. Understanding the failure mechanism of the alloy helps to develop better alloys for similar complex environments. Samples of as-cast alloy and those taken from failed ones were examined. Optical Microscopy (OM), X-Ray Diffraction...
