WebOct 28, 2010 · To put it more simply, forging ratio or work reduction ratio (for products other than forgings) is typically defined by the end user or design organization, and is based on intended service conditions of the end product. It really is an engineering process detail step that has been developed by experience from the end user. WebAug 3, 2014 · At reduction ratios from 2 to 6 the difference in the impact toughness of the specimens cut from central and peripheral zones of the forging attains 20 – 40%. The strength parameters σ 0.2 and σ r vary within 10% upon growth in the reduction ratio.
