Control factors for determining the alpha-W phase microstructure of a directionally solidified Ni-W in-situ eutectic composites was investigated. The relationship between direction of a eutectic grain and the miorostructure was examined using the back-Laue method. Influence of the growth rate on the transition of the microstructure was also examined by increasing the growth rate in the middle of the directional solidification. The experimental results reveal that both growth rate and deviation of the gamma-Ni <100> direction amplified the aspect ratio of the transverse alpha-W-phase microstructure. We already make speeches these results at the annual meetings of Japan Institute of Metals, and will be published at the Journal near future. And we are intending to make speech at the International Conf. of Casr Composites at Polland in 1995.As for the models of Ni-W eutectic alloy, we also investigated Al-Si eutecti alloy. In this case the modification of the Si was caused with the adsorption of Sr at the interface. We already contributed many articles to the journals of Japan Institute of Metals and Japan Foundryme's Society.

研究了影响定向凝固Ni-W自生共晶复合材料α-W相组织的控制因素。用Back-Laue方法研究了共晶晶向与显微组织的关系。通过提高定向凝固中间的生长速率，考察了生长速度对组织转变的影响。实验结果表明，生长速度和取向偏差都增大了α-W相横向组织的长径比。我们已经在日本金属学会的年会上发表了这些成果，并将在不久的将来发表在期刊上。我们打算在国际会议上发表演讲。关于Ni-W共晶合金的模型，我们还研究了Al-Si共晶合金。在这种情况下，硅的改性是由于锶在界面上的吸附引起的。我们已经在日本金属学会和日本基础学会的期刊上发表了多篇文章。
