The corrosion resistance and mechanical properties of the 690 protect tube after solution treatment have been studied with scanning electron microscopy (SEM), tensile and electrochemical corrosion test. The results showed the mechanical property would be deteriorated obvious when the solution treatment temperature over 10:30°C. Instantly, the mechanical property could be keep in a stable level if the temperature equal or below 10:30 °C. The macro grain morphologies SEM photos showed the grain sizes grown too big to keep mechanical properties. The ectrochemical corrosion experiments reveled the corrosion resistance property of the samples which are treated at 10:30 °C, 1070 °C, 1100 °C is better than the treatment temperature are 950 °C, 990 °C . Resides, the Ecorr and Icorr of the sample heat treated at 10:30 °C is -0.01 V and -9.09 A/cm² respectively. The data presents the sample has the best corrosion resistance property. Consequently, the corrosion resistance and mechanical properties of 690 protect tube has best property which solution treatment at 10:30 °C in this study. [ABSTRACT FROM AUTHOR]

In order to explore a technological route of higher mechanical quality factor constant elastic alloy, the effects of aging heat treatment regime, cold deformation and chemical composition on the mechanical property, mechanical quality factor Q and elastic modulus E of alloy Ni40Cr4Ti2,M0Nb were investigated respectively. The results showed that aging heat treatment could obviously improve mechanical property and cold deformation was the main factor on Q. Further more, the variation of w(Mo) % contributed very little on Q an d E, especialy E . Through 650 °C X :3 haging he at treatment combined with 40% deformation on the 3# sample which owned 1.84 % Mo element, an expected high mechanical quality factor constant elastic alloy with Q of 46866, elastic modulus of 186. 9 G pa and the tensile strength beyond 13 66 Mpa was obtained.
