工学入門シリーズ　熱処理

Summary Produced by: Nikkei Films, Planning: Ministry of Education 1962, Black and White, 26 minutes Heat treatment primarily involves quenching, annealing, and tempering, which soften or harden carbon steel. Depending on the heating temperature and cooling rate, austenite, martensite, and pearlite crystallize. Surface hardening is also a process. This film uses a metallurgical microscope to reveal many previously difficult-to-see structures, and provides unique explanations.
