Dendrite coherency of al-si-cu alloys
Did you know?
WebThe dendrite coherency point of Al-Si-Cu alloys was determined by thermal analysis and rheological measurement methods by performing parallel measurements at two cooling rates for aluminum alloys across a wide range of silicon and copper contents. Contrary to previous findings, the two methods yield significantly different values for the fraction solid … WebThe authors of [57] looked at Al-Si-Cu alloys and examined how the addition of Sn would affect their mechanical properties (including the addition of Ti). This confirmed the results …
