Effect of Solution Treatment Temperature on Microstructure and Mechanical Properties of Cr20Ni32AlTi Alloy

Abstract:

The effect of solution treatment from 1050°C to 1200°C, soaking time 15min on microstructure, mechanical properties and precipitation behavior of Cr20Ni32AlTi alloy was investigated. The results are as follows: with the increasing of the solution treatment temperature from 1050°C to 1200°C, the average grain size increases remarkably from 17μm to 110μm, the strength of alloy decreases while the elongation increases. The amount of carbide precipitation in the alloy decreases with the increasing of solid solution temperature. The optimum solution treatment temperature for the investigated Cr20Ni32AlTi alloy is 1150°C~1200°C.
