【摘要】：利用Forge模擬軟件對718高溫合金在徑向鍛造過程中溫度場、等效塑性應(yīng)變場、最高溫度變化和散熱情況進(jìn)行了研究.在第一道次,坯料升溫集中在表面至距離心部1/2半徑處;第二道次后心部成為溫度最高部位,且心部溫度較之前趨于均勻,心部溫度最終比初始溫度升高約45℃;坯料最高溫度在徑向鍛造過程中先升高而后略微降低;在所有散熱形式中,熱輻射是坯料散熱的主要方式;對等效塑性應(yīng)變的模擬發(fā)現(xiàn),坯料在第二道次鍛造后已被鍛透.現(xiàn)場取樣觀察與模擬結(jié)果對比顯示,模擬結(jié)果具有可信性.
[Abstract]:The temperature field, equivalent plastic strain field, maximum temperature change and heat dissipation of 718 superalloy during radial forging were studied by Forge simulation software. In the first stage, the billet heats up from the surface to the radius of 1 / 2 from the center, the center of the second pass becomes the highest temperature, and the temperature of the center tends to be uniform, and the temperature of the center increases about 45 鈩，
