Next, in an evaluation step, compressive residual stress and surface roughness of a region shot-peened in the trial peening step are measured and an extent of shot peening treatment in the trial peening step is evaluated based on measurement results. Next, in a peening step, a surface of the water cooling hole 42 in the mold 40 is shot-peened under peening conditions set based on peening conditions for the trial peening step and on evaluation results produced in the evaluation step."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shot peening method, shot peening evaluation method, and shot peening evaluation assembly structure","description":"In a trial peening step, a shot peening process is applied to a back face 40B of a mold 40 in which an opening of a closed-end water cooling hole 42 is formed.
