根据实验结果可知，添加0.4%Er可使合金具有较为优异的综合性能。

Results of the experiment show that, 1 proper semi-solid remelting temperatures of the alloy is in the range of 570℃-571℃; 2 in the condition of optimized reheating processing, the temperature deviation in a billet is O℃-1℃; 3 dendritical colonies of a phase in original billet changed into isolated grains with forms of nodules and granule, which may satisfy the need of semi-solid thixoforming forming in theory.

实验结果表明：1该合金合理的半固态二次重熔温度为570℃-571℃；2在优化的感应加热工艺条件下，半固态重熔坯料内部的温差在0℃-1℃；3半固态重熔过程使原始料坯中的α枝晶组织变成球团状和节杆状组织，满足了半固态触变成型的要求。

The results have shown that Ti-6Al-1.8C is composed of Ti and TiC reinforcements that are of two different morphologies: coarse dendritical primary TiC and short bar-shape eutectic TiC.

结果表明：在Ti-6Al-1.8C中主要存在Ti和TiC两种相。

The photos of TEM showed that the average size of nano-silver particulate was about 15—25 nm, which was equal to that by Zetasizer, and that nano-silver particulate were fractal assembling into ordered dendritical aggregation structure.

实验表明，在超声辐射下，不需任何还原剂，Ag~+可被还原成银原子，进而聚集成纳米银微粒，尺寸在15—25nm，这种纳米银能够分形生长，最终成为树枝状的有序聚集体。

The analyzed results about the forming mechanism of TiC indicate that the dendritical TiC is the primary TiC which freely grows in a continuous growth way in supercooling liquid metal before the peritectic reaction, and the short bar-like TiC nucleates and grows in β—Ti after peritectic reaction.

在对TiC形成机制的分析中认为，树枝状TiC是包晶反应之前过冷熔体中，以连续生长方式自由生长而成的初生TiC，而短棒状TiC则是包晶反应后在β-Ti的内部生核并长大而成。
