Title: Vacuum heat treatment method
Inventor: WATANABE KAZUHIRO
IPC: C21D1/773
Filed: 1992-12-16
Abstract: PURPOSE:To secure strength and ductility by introducing a pressurized cooling gas exceeding the atmospheric pressure to make a quenching speed larger after a member to be heat treated is placed in a vacuum container and heated in vacuum. CONSTITUTION:At introducing a compressed gas into a high temp. vacuum furnace, a gas temp. is lowered due to adiabatic expansion, producing the cooling effect of gas. Because a temp. range of 400-750 deg.C makes the heat transfer due to heat conduction and heat convection rather than heat radiation the main stream, in order to improve heat transfer, the gas pressure is elevated, increasing the gas density. The way of gas cooling is different in a cooling speed depending on material and thickness, accordingly, it is preferable to control a pressure applying method and gas introducing speed.
