Abstract
Investigated the accuracy improvement for specimen preparation of Ni-based single-crystal superalloys of elastic property measurement by using IP laue camera. After determining the crystal orientation by IP Laue camera, the specimen and cross goniometer head moved to cutting machine together. Performing the reinforcement of the cross goniometer head stage , also adjusting the granularity of the abrasive the cutting blade, so it was improved the cutting sa d and angle accuracy . Prepared specimen in such procedure verified the accuracy of crystal orientation using by X-ray, ultrasonic and resonance method.
