The goal of the project is to evaluate the strain-stress behavior of metallic coating on a metallic substrate using in-situ 4-point bending set-up or other loading set-up in a XRD system. Other methods and approaches can be also evaluated. Phase one: design the specimen relative to the loading cell. The specimen will be provided by PW and may have slight curvature. The metallic coating is up to 100um. Phase two: design the measurement experiment in the XRD system. Define loading increments and measurement protocol. Phase three: run measurements of 2-3 coupons with various compositions or microstructural changes. Assess measurement error, repeatability and changes in strain stress behavior coupon to coupon.
