Research Abstract

The project has been titled aiming powder processing at becoming one of fundamental technologies for fine production. It is not proper to use the conventional approach in which trial and error is applied by the relative comparisons among the tested results because of lacking efficiency and easy misjudgment. Instead, it is important to establish a method with the trustworthiness and reproducibility of testing. It contains searches for the substantially satisfied characters of discrete phases such as powders and short fibers as raw materials and of heterogeneous multiphase/porous structures such as sintered parts as products. It shows not only the quantified analyses of tested results but also the revelation of factors concerned and the evaluation of how much their influences have. There is a proposal that the distributions of the characters should be statistically determined for the relationship to materials characteristics. A systematic study planed is of various tests in which the individual discussions are possible. It is fortunate to get a high appraisal abroad and domestically of the summarized generalization from a lot of findings. The unique has brought about a book intended for final year undergraduate and post graduate students of materials science and engineering and those researchers and industrialists working with powder processing techniques, "New Quantitative Approach to Powder Technology," from John Wiley and Sons Ltd. It has been also appreciated by two Awards, one for Innovatory Research "A Study on Quantitative Analyses of Powder and Powder Processing" and another for Distinguished Achievements in Research "Creation and Application of New Quantitative Approach to Powder Technology" from the Japan Society of Powder and Powder Metallurgy.
