Overheating of Waspaloy: Effect of cooling rate on flow stress behavior

• Tensile tests with prior overheating on Waspaloy were performed utilizing precise temperature controlling capability of electro-thermal mechanical testing system. Overheating at 1000 °C a cooling rate 50 K/s severely decreased tensile properties 700 °C. Significant dissolution precipitates is the reason property loss. Sufficient re-precipitation and growth for can occur during slower 1 K/s. Microstructural response thermal history be observed using in situ resistivity measurement. During service gas turbine engine, components may suffer instant which concern to safe operations. Effect short Ni-based superalloy has been studied due its significant importance practical applications. The results have shown that combination near supersolvus very rapid most detrimental case material. This attributed absence ? ? carbide period. Microstructure change deduced in-situ measurements. work provides evidence multilateral measurements including shed light failure parameters.
