다국어 초록 (Multilingual Abstract)
An investigation was carried out to develop the abrasion-and heat resistant P/M alloy steels for an application to valve seat of diesel engine. The alloy powder obtained by mixing the individual elemental powders was compacted and sintered by conventional P/M technique and the sintered specimen was subjected to the usual heat treatment for hardening.
Under the optimal sintering-and heat treatment condition; (sintered at 1200℃ for 100 min., oil quenched from the austenitizing temperature of 850-900℃ and tempered at 550℃ for 60 min.) the ultimate tensile strength of the sintered alloy steel was more than 1300 N/㎟. It has also shown the appropriate hardness and elongation, as 40.5 HRC and 3%, respectively.
Under the optimal sintering-and heat treatment condition; (sintered at 1200℃ for 100 min., oil quenched from the austenitizing temperature of 850-900℃ and tempered at 550℃ for 60 min.) the ultimate tensile strength of the sintered alloy steel was more than 1300 N/㎟.
