lack of fusion-
Liquid - solid extrusion of composite material is a new kind of metal forming process, which has been developed in recent years with a promising practical application prospect for its simple working procedure, low cost and good workpiece performance. through a lot of experiments, the optimization and chosing method of key process parameters ( pouring temperature, mold warm - up temperature, impregnating pressure, impregnating time ) has been mastered. under the precondition of appropriate chosing these parameters, the effective control of extrusion velocity is the key of mading good workpiece. but the control of extrusion velocity remains a handwork, and it is heavily affected by such uncertainties as a handler ' s knowledge and skill about the process. in order to solve the problem, the automatic control of the extrusion velocity is studied, and a computer control system is also designed under existing condition
通過大量實驗，已掌握了關鍵工藝參數（熔液澆注溫度、擠壓模預熱溫度、浸漬時間、浸漬力）的優化選取方法。在合理選取關鍵工藝參數的前提下，擠壓速度的控制是成形出質量良好製件的關鍵。但是，目前對于擠壓速度的控制仍停留在手動控制階段，利用該工藝制備管、棒材製件的成功與否受操作者對該工藝及其設備的經驗及熟練程度等不確定因素影響很大。The dcep mig has the characteristic of deeper penetration which can reduce defective fusion and good arc stabilization. the dcen mig has the characteristic of shallow penetration of welding seam, and the welding wire has a high melting speed. so the variable polarity pulsed mig is a new technology for the welding of aluminium alloy sheet
變極性脈沖mig焊是一種新的焊接工藝方法，其綜合了dcep脈沖mig焊熔深較大、可以減少焊縫的熔合不良、電弧穩定性好和dcenmig焊焊縫熔深淺、焊絲熔化速度較快的特點，減小了焊縫的熔深，增加了焊絲的熔化速度，是一種適合於薄板鋁合金焊接的新方法。While this special modified hot zone will not create a specific temperature differential, it does offer a convenient way to get more heat energy into a specific area of a furnace
這種特殊的改良后的發熱部不會引起特別的溫度變化，反而更方便的使熔爐內一些特別區域得到更多的熱量。In the process of alloy melt and infiltrate the boron carbide, reaction between the boron carbide and aluminum interface occur, the key of achieving a good interface bond is the control of the reaction between the boron carbide and aluminum interface
研究表明，在熔融鋁潤濕碳化硼預制體並向碳化硼預制體中浸滲的過程中，取得良好界面結合的關鍵是保證在預制體達到完全浸滲前不發生過度的界面反應。分享友人
