熱処理CAEソフトウェアを活用した低合金鋳鋼材の焼割れシミュレーション Simulation of Quenching Crack Generation in Low Alloy Cast Steel by Using Heat-treatment CAE Software 内田, 富士夫 進藤, 亮悦 鎌田, 健一 後藤, 正治 UCHIDA, Fujio SHINDO, Ryoetsu KAMADA, Ken-ichi GOTO, Shoji low alloy steel casting 熱処理CAE heat treatment CAE software 低合金鋳鋼材 quenching crack 焼割れ In order to understand the quenching crack phenomenon in cast steel, a disk shaped low alloy cast steel specimen having a opening was quenched in water at 1123K. The behavior of a quench crack was investigated by microstructure observation and analyzed by the Heat treatment CAE software. The results obtained are as follows. （1）The quench cracking easily occurred as the volume of specimen increased. The mass effect for quenching crack was significant. （2）The quench cracking was due to time lag in martensitic transformation at surface side and inner side of the quenched specimen, but not due to the thermal stress in the specimen. （3）The behavior of a quenching crack was able to be predicted by the Heat treatment CAE software. （4）Therefore, the Heat treatment CAE software is useful for a counterplan preventing the quenching crack. journal article 素材物性学会 2004-06-01 VoR application/pdf 素材物性学雑誌 1 17 8 12 https://air.repo.nii.ac.jp/record/823/files/sozai17-1b.pdf http://hdl.handle.net/10295/596 https://air.repo.nii.ac.jp/records/823 jpn open access
