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 precision lapping technology to machine the copper substrate using semi-fixed abrasive plate was studied. The surface roughness and material removal rate as the evaluation of indicators, the influences of the different lapping parameters on the surface roughness and material removal rate were discussed and analyzed. Experimental results indicated that the copper substrate could be efficiently machined by semi-fixed abrasive plate of 800(superscript #) SiC abrasive, and the initial roughness Ra of a machined surface could be improved from 0.553μm to 0.28μm in 10min, produced an ideal rarely scratch surface. Then processed copper polished by diamonded grinding paste, it could be satisfied for the Ni-Pd-P alloy thin film growth.
