To achieve a homogeneous microstructure throughout the cross-section, the rod sample was rotated with 60° around the longitudinal axis (MP-HPS-R) for three times. A microstructure with an average grain size of 280 nm was developed around the center of the cross-section through the MP-HPS-R process. Superplasticity with total elongations of more than 400% was achieved in the 9 mm diameter range on the cross-section of the MP-HPS-R-processed rod.}, pages = {63--65}, title = {マルチパス高圧スライド加工(MP-HPS)によるAl–3Mg–0.2Sc(mass%)合金棒材の大径化と結晶粒超微細化}, volume = {70}, year = {2020}, yomi = {ホリタ, ゼンジ} }
