 note = {Qrdinarily the heat treatmenls of low carbon steels are difficult for the "Mass Effect". But the sheets of low carbon steels showed good mechanical properties with the good designed heat treatments. So the authors investigated the conditions of the heat treatment of low carbon (from 0.099 % to 0.29 %) steels. According to our results the qucnching temperature is 100℃～150℃ upper from AC_3 point in the Fe-C phase diagram and decreases with the decrease of carbon contcnts. These results was obtained with the specimens quenched in water and the specimens quenched in oil. The later did not show the same behabiours so sensibly., 軟鋼のAc_1点以上の温度からの焼入については質量効果に問題があるが薄銅鉱では焼入温度を適当にとれば望ましい機械的性質の得られることがある。即ちC0.17%の軟鋼鉱では焼入温度を950℃～1000℃にとった場合，衝撃値，繰返し曲げ，疲労限が最大となることを著者等の一人が既に報告したがその原因を追究するとともに更に実用上の見地からも炭素量を異にした鋼銀で同様な実験を行った。, Article, 富山大学工学部紀要，8(1/2), Page 64-69},
