摘要
Abstract
According to the single crystal residual stress measurement proposed by Hiroshi Suzuki et al ., the measurement for φ ,ψ and the diffraction peak position 2θn corresponding to different crystal face normal line of the same crystal face group were performed .After the equation group was established ,the coordinate transformation matrix was obtained by using linear regression method , and the stress matrix of sample coordinates was calculated , to avoid d0 measuring precision being affected . This method was successfully applied to measure residual stress of nickel‐base directionally crystallized superalloy blade using the IXRD stress analyzer , and a powerful technical means for the process parameter optimization of directional crystallization blade was provided .关键词
