Some other defects in castings are well - defined cracks and hot tears that develop during solidification, under combination of stress concentration from uneven contraction and the metal ' s low strength at near - melting temperatures
鑄件內部的其它一些缺點是,凝固過程中,在不均勻收縮造成的應力集中和接近熔點溫度下金屬的低強度的綜合作用下,出現的清晰裂縫和熱撕裂。However, the disadvantage of laser welding is the so - called post - weld - shift ( pws ). the end result is a reduction in light coupling efficiency. the shrinkage force generated by the solidification process is so great that no known mechanical structure can counteract the shrinkage from shifting the joint ? at least at the micron level
這種封裝技術最大的缺點是會使激光二極體的封裝產生焊後偏移( pws ) ,很少有一種機械的方法可以校正這種焊後偏移到亞微米級別,目前激光錘被證明是一種很有效的校正方法,激光錘校正作用過程就是利用金屬熔化凝固冷卻產生的內應力來恢復焊後偏移的過程。Research progress of rapidly solidified magnesium alloys
