초록

Fe-30Ni-0.35C 합금과 몇가지 저융점 순금속의 상변태에 미치는 압력의 영향에 대하여 PDSC를 이용하여 조사하였다. Fe-30Ni-0.35C 합금의 오스폼트 마르텐사이트 및 마르폼드 마르텐사이트 오스테나이트로 역변태시 압력이 1 기압에서 60기압으로 증가하에 따라. A s 점이 약 2 4 ? C 저하하며, 이것은 상전이시의 체적변화가 음의 값이 되기 때문이다. 또한 A f 점은 압력이 증가함에 따라 변함없이 일정하거나 매우 미소한 상승을 나타내는데, 이것은 압력이 증가할수록 탄화물의 석출이 촉진되기 때문이다. Fe-30Ni-0.35C 합금의 오스폼드 마르텐사이트의 역변태시 엔탈피변화는 압력이 1 기압에서 60기압으로 상승함에 따라 10~14J/g 증가한다. 순금속 Se, Sn, Pb, Zn, Te 등의 용융점은 압력이 1기압에서 60기압으로 증가함에 따라 매우 완만하게 상승하며, 용융시의 엔탈피변화는 압력의 증가에 따라 거의 변화가 없거나 미소 증가를 나타낸다.

The effect of pressure on the phase transformation in Fe-30Ni-0.35C Alloy and pure metals was investigated by using PDSC(pressure differential scanning calorimeter). As the pressure increased from 1 atm to 60 atm, the A s points of the ausformed martensite and the marformed martensite in Fe-30Ni-0.35C Alloy were lowered about 2 4 ? C at reverse transformation. This is why the volume change came down at phase transition(from martensite to autenite). As the pressure increased from 1 atm to 60 atm, A f points were constant or slightly increased. This is due to the promotion of carbide precipitation with increasing pressure. The enthalpy change of the ausformed martensite in Fe-30Ni-0.35C Alloy was increased by 10~14J/g. The melting points of the pure metals, Se, Sn, Pb, Zn and Te were slightly increased with increasing pressure. The enthalpy changes of the pure metals at melting were little changed or slightly increased with increasing pressure.
