During the temperature fields , the results indicate that the processing parameters such as the extrusion velocity , casting temperature , perform preheating temperature , die preheating temperature and so on are important for the temperature fields besides the dwell time . they are must be in concordance each other to the deforming zone is in the quasi - solid state , and the stable semi - solid extrusion is implemented . during the deforming fields , the hyperbolic sine thermo - rigid - viscoplastic fem model is selected according to the forming feature of the process , and the variations of the stress - strain fields are studied 在溫度場(chǎng)的模擬中,模擬結(jié)果表明,保壓時(shí)間是影響制件成形質(zhì)量的關(guān)鍵因素之一,擠壓速度、液態(tài)金屬澆注溫度、預(yù)制體預(yù)熱溫度和模具預(yù)熱溫度等工藝參數(shù)對(duì)溫度場(chǎng)的影響也很大,需進(jìn)行參數(shù)之間的協(xié)調(diào),只有當(dāng)變形區(qū)內(nèi)部始終維持準(zhǔn)固態(tài)時(shí),才能實(shí)現(xiàn)穩(wěn)定的液-固擠壓成形過程;在變形場(chǎng)的模擬中,根據(jù)液態(tài)浸滲擠壓的成形特征,選用了雙曲正弦剛-粘塑性有限元計(jì)算模型,研究了變形過程中應(yīng)力應(yīng)變場(chǎng)的變化規(guī)律,研究了模角對(duì)變形和金屬流動(dòng)的影響及變形力的變化過程和其影響因素。
