Title: Hot forging method of powder
Inventor: TAKEDA YOSHINOBU
IPC: B21J5/00
Filed: 1980-06-10
Abstract: PURPOSE: To obtain superior mechanical strength without resintering, by subjecting the powdery compact made of steel containing a prescribed amount of an easily  oxidizable alloy element to vacuum sintering and by performing hot forging at a  prescribed temperature.  
     CONSTITUTION: Powder of steel containing 0.8W10wt% one or more kinds of easily oxidizable alloy elements selected among Mn, Cr, Si, and V is compacted. This powder is sintered at 1,200°C for 30min in 10 -3 Torr vacuum, thereafter hot forging is carried out in an atmosphere of inert gas at 900W1,200°C. This method accelerates the sintering remarkably, increases binding strength and reduces internal inclusions, suppressing the occurrence of microcracking. Therefore, superior mechanical strength is obtained even when resintering is not carried out after the  forging.

Abstract: PURPOSE:To simplify constitution and reduce dimension and economize electric power by installing a shape memory alloy member which attaches a heat radiation part onto a heating part against the urging power of an urging means by a contraction force at the drive of the heating part. CONSTITUTION:When a gas decomposing part 11 and a heating part 12 are driven, the generated heat in the heating part 12 increases, and the temperature rises. Then, in a heat radiation shielding mechanism 16, a driving part 17a is shifted in the direction of arrow A and set close to the heating part 12 by the contraction of a shape memory alloy member 17.

Therefore, the generated heat in the heating part 12 is irradiated outside through the heating member 15 and heat radiating coating part 15a, and a heat control is carried out. Therefore, the need of installing a heat insulating heater is obviated, and the dimension can be reduced, and the economization of electric power is contrived.
