Forging ratio at elongation is most often calculated with use of simple relations, which are based on the change of cross section of the forged pieces. The intensity of structure development is influenced not only by the simple change of cross sections, but also by relative length of the stroke, magnitude of deformation in individual passes, manner of edging, temperature, friction and shape of anvils. The paper gives an analysis of influence of the relative length of the stroke on the forging ratio.展开更多

Since the major deterioration factor affecting the storability of lokum is moisture gain or loss, the effect of the possible ambient conditions （32%, 53%, 75% RH and 15, 25, 35 ℃） on weight change and firmness of tokum was determined to estimate its structural changes. The variations in thermal properties of lokurn samples stored at different RH （32, 53, 65, 75, and 85% RH） were also determined. Increasing RH decreased glass transition of lokum samples, and two glass transitions （Tg） were observed at 75 and 85% RH. The presence of the second Tg could be related with phase separation which was increased with increasing moisture content and RH. Lokum should be kept at around 50% RH and 15℃, higher storage RH＇s and temperatures will cause the product to become unacceptable by the consumer within 20 days.展开更多
